San Francisco Sewage Clean Up
San Francisco Raw Sewage Clean Up A raw sewage spill inside your home or business can happen
to anyone at anytime with catastrophic consequences. If it happened to you, you need to act fast.
Many causes send sewage into a structure like floods, earthquakes, fires, and other misfortunes.
Once the problem is found and repairs are made, you're left with the muck and the smell. Raw
sewage is dangerous, contaminating everything it touches and making the air hazardous to breathe.
Don't Try This at Home Cleaning, sanitizing, and removing the debris of a raw sewage spill is a
hazardous process, which should be performed by trained professionals. Keeping your family,
employees, customers, and pets safe takes more than a mop and some spray disinfectant. Allied

6. Decentralized Wastewater Systems Regulatory and Economic Challenges
During the last twenty years the USEPA has been evaluating decentralized wastewater treatment
technologies as a reliable alternative for wastewater treatment. In 1997, the EPA submitted to
congress its Report and subsequent documents endorsing decentralized wastewater treatment as a
permanent long–term solution for wastewater treatment. The Report stated that adequately managed
decentralized wastewater systems are a cost effective long–term option for meeting public health
and water quality goals, particularly in less densely populated areas. The following is a summary the
key components of the Report:

Also decentralized systems are suitable for a variety of site conditions, including shallow water
tables or bedrock, low–permeability soils, and small lot sizes. One of the additional benefits is that
decentralized systems are also suitable for ecologically sensitive areas (where advanced treatment,
such as nutrient removal or disinfection is necessary). Since centralized systems require collection
of wastewater for an entire community at substantial cost, decentralized systems, when properly
installed, operated and maintained, can achieve significant cost savings while recharging local
aquifers and providing other water reuse opportunities close to points of wastewater generation
(USEPA 1997). This benefit not only help alleviates the cost burden but also helps to improve the
watershed conditions.
The EPA Report also evaluated the obstacles that decentralized system may confront and ways to
overcome the barriers were presented. The following are the most common barriers for the
implementation of decentralized systems:
Lack of Knowledge and Public Misperception. The perception of some homeowners, realtors, and
developers that centralized systems are better for property values and are more acceptable than
decentralized systems, even if they are far more costly, makes it difficult to demonstrate that

The Importance And Uses Of Wastewater Treatment
Wastewater treatment is important in many ways. One reason that it is so important is because, at
the plant, they water and other things as well. In the Middle Ages in London people had laws and
regulations about waste treatment (O'Neill, 2013). Without wastewater treatment most species of
animals would be extinct because the water in lakes and oceans would be polluted with human
waste. Wastewater treatment is important because it keeps the Earth clean, it recycles more than just
water, and it saves animal species from becoming extinct.
Wastewater treatment keeps the Earth clean because without it humans would not have a steady
source of drinking water. Back in the Middle Ages people were concerned about water treatment.
People were heavily fined if they were caught dumping sewage into the streets. Instead, the people
would take their buckets filled with raw sewage and dump it into nearby rivers and streams. This
was extremely unsanitary. The bacteria, or decomposers, would break down the waste but there was
so much that it took a long time.The people didn't know how disease was spread by waste. They
thought that it was by its odors (O'Neill, 2013). People who owned larger houses had people come
and clean their enclosed latrines. Even further back, the Aztecs had a waste system where all of the
human waste would be used as fertilizer for their crops (Medina, 2014). Then the saprophytic
bacteria would do the rest, consuming the decomposing matter. Saprophytic bacteria

Wastewater Treatment
Introduction
The increase in the number of individuals in the planet has established a boom in technology, and
industry, which advances the problems in the economy, and contributes to the degradation of the
environment. Evidently, the treatment and collection of the wastewater in urban areas poses a
critical problem especially in developing countries. Wastewater is a practice that has been taken on
especially in urban areas where the domestic effluent pollutes surface water bodies creating health
problems for the public. In another word, any water that has been affected by anthropogenic
influence. And Wastewater can produce a group of activity that consists of domestic activity,
industrial activity, commercial activity, surface runoff or storm water, and from sewer inflow or
infiltration. Wastewater is the most important thing that can help people moving comfortably for
example when it is raining. Especially, when vehicles move around the city this Wastewater can
reduce the hazards of sliding vehicles at road. Also, wastewater can avoid wastefulness of water and
can help the agriculture environment by irrigation. On the top of that, the wastewater will help grow

Tree roots are the most common unpreventable cause of sewage backup. The tree's roots move
towards sources of moisture, and as a result, they rupture the underground pipes. Older pipes can
also cause an issue with raw sewage because the materials used often include: clay or soft metals.
When it comes to a sewage backup, heavy rain has sometimes been the culprit. For example, the
overflowing water, leaves and tree branches can leave debris that causes flooding and clogging of
your sewage system. How can Business Owners and Homeowners Handle This? The best method is
to leave the overall cleanup to the professionals. However, you are the first to take notice of an
accident. For that reason, you can take specific steps to prevent further damage and maximize
safety. First, limit your contact with the sewage, and second contact a professional sewage clean up
in Marin. You will also want to purchase safety equipment such as eye protection, gloves, rubber
boots and a breathing mask. Do not wear them anywhere other than around the sewage spill. You
also want to keep your surrounding areas as clean as possible. If you have people who are sick or

Building A Conventional Sewage Treatment Facility
As in the case of rural non–point source pollution; urban areas are not likely to fix all contamination
problems with one system. While it may be possible to build a conventional sewage treatment
facility that can handle any storm condition it is not likely that this will ever be cost feasible to do.
One type of larger combined sewage system that is being tried in several locations around the
county where proper topography allows is the aquatic marsh system. In this type of system sewage
still goes through the primary treatment of separation out the larger solids. Once these solids have
settled out it move on to the secondary treatment where it undergoes another process to remove
biochemical oxygen demand. This is done through introducing ... Show more content on

While the wet–land treatment system is very effective in treating large quantities of sewage it still
falls short of the large problem. It still is not treating the problem at its source. There are other
options and systems that are in place to deal with urban pollution issues and flooding. Some
example of systems that have the potential to mitigate urban at their source are implementing low
impact development, installation of sand filters, infiltration trenches permeable pavers, storm water
planters and green roofs. Low impact development (LID) is not a new concept but is still considered
innovated when being discussed. LID is a storm water management program that manages storm
water on site compare to conventional systems that pipe it off to a central treatment facility or
directly into local water ways. Storms waters in the natural environment normally soak into the
ground and are filter by the soils and vegetation. When areas are urbanized the water now running
off taking contaminate with them. These waters can flow at fast rates causing increased flooding.
The goals of LID are to lessen the impact storm waters on the natural environment, use land more
efficiently, and help to lower cost. Site planning includes, "minimizing areas of disturbance,

This report is based upon the collected data from scientific tests and different data collection
experiments, these diverse range of observations helped in determining the health of the river and
catchment as a whole. The experiments tested a range of variables, some including; the levels of
nitrates, phosphates, temperature of water, pH levels, turbidity of water and dissolved solids. The
collection of water and recordings of microorganisms was examined and also recorded. As well as
these scientific tests, simple recordings were also taken of the surrounding area and the amounts of
rubbish and infrastructure that could be seen. The tests conducted in the river system occurred on
the 24th of May 2016, to conduct the tests the trail along the river was walked, furthering the
knowledge of the health of the river and how the the catchment area as a whole was fairing.

Negative Effects Of Urban Development On The Environment...
Beaches are some of the most romanticized places on the planet, for good reason; however, the
encroachment of humans onto beach and coastal habitats has resulted in several negative outcomes.
At Santa Monica State Beach (and adjoining pier), one of the most popular and polluted beaches in
California, the impacts of urban development, industry, and other man–made problems have caused
mass pollution in the surrounding environment. The effects this pollution has on the coastal wildlife,
water quality, and human health are catastrophic to the ecology and natural habitat of the beach. The
beach began to decline in the early twentieth century with the construction of the Santa Monica Pier
in 1909 after sixteen weeks of construction that on its own resulted in many tons of concrete being
poured into Santa Monica Bay (City of Santa Monica, 2015). Over the next few decades land
developers, and beach goers alike contributed a toxic combination of chemicals, bacteria, and trash
that has resulted in Santa Monica Bay having several dead zones (Heal the Bay, 2015), which
devastate the marine life population.
Geology of Santa Monica Beach There is relatively little information on the natural geological
history of Santa Monica State Beach; however, there is an explanation as to why. The beach was one

Effects Of Urbanisation On The Hydrology Of A Catchment
Question 1 a) Explain the affects that Urbanisation can have on the hydrology of a catchment.
Outline how SuDs can mitigate these impacts and explain the role and features of the following
systems: Permeable pavements Swale Detention Ponds Urbanisation affects the hydrology of a
catchment in various ways, it causes issues with the natural drainage of the environment by blocking
stream channels and removing trees which help break the momentum of rain. Urbanisation creates a
lot of surfaces that are impermeable which causes water build up, the water picks up pollutants and
chemicals and these are dispersed into streams and rivers. Roads and pavements collect rainwater
and channel it into waterways rather than letting it disperse into the ground, like it would if it had
not had any human intervention. SuDs have been introduced within construction projects now in
order mimic the natural drainage pattern of a specific area, these SuDs that are now being
introduced are aiding urban developments in allowing surface water to be managed well without
causing any impact on other sites. Permeable paving comes in a range of materials, it was designed
to allow water through a surface that would have usually be impermeable, they are generally used
on pathways, lawns and roads that only take light vehicle movements. They essentially reduce
surface water run–off, which traps solids and filters some pollutants from the water, they also give

Causes Of Water Logging In Dhaka
WATER LOGGING PROBLEM AND DRAINAGE IN DHAKA
IN RECENT years Dhaka City has been facing extensive water logging, especially, during the
monsoon. Even without climate change, likely damage from waterlogging in Dhaka by 2050 is Taka
11,000 crore. In a changing climate with more intense rainfalls, the loss will be Taka 139,000 crores
between 2014 and 2050. These damages can be reduced significantly to Taka 3,700 crores, if Taka
270 crores investment is made. The amount Taka 270 crores is equivalent to only 0.35 percent of the
government's annual development budget expenditure for 2014–2015.(World Bank,2015).Problems
that occur in the city are increase in water pollution, traffic congestion, air and noise pollution, solid

low capacity and gravity, natural siltation, absence of inlets and outlets,indefinite drainage outlets,
lack of proper maintenance of existing drainage system, and over and above disposal of solid waste

Construction Of An Underground Network Of Tunnels
Introduction
In the 1850s over 400,000 tonnes of waste and sewage was being discharged into the River Thames
each day. By 1858 the stench from the raw sewage around and within the Thames was named the
'Great Stink'. It was a Civil Engineer named Joseph Bazalgette who proposed a plan of the creation
of an underground network of tunnels, to put an end to the polluted river. His engineering feat has
been improved and extended vastly but the Victorian Sewers still stand as London's primary sewer
system. The sewers were designed to be a combined system meaning rainwater and waste were
transported in the same manner. Bazalgette designed Combined Sewage Overflow (CSO) points
along the Thames. The CSO's discharged the sewage and rainwater into the Thames after substantial
rainfall, this prevented flooding the streets and houses. When designing the sewers, population
increase was taken into consideration. (16) The underground system and factories were designed to
treat and transfer sewage of up to double the population that was present when construction began.
However the population of London almost quadrupled from 2.35 Million in 1850 (19) to 8.17
million in 2011(7). This drastic increase meant that the sewers were overloaded. The CSO's were
overflowing with only 2mm of rainfall and on average discharging into the Thames around twice a
week. The head of Thames Water Phil stride, said "Currently, 32 million cubic metres of storm

Phycoremediation And Environmental Pollution
The rapid growth of human population and industrialization has lead to the environmental pollution
and the world is facing problems with a wide variety of pollution (Kshirsagar, 2013). The release of
wastewater poses serious environmental challenges to the receiving water bodies (De–Bashan et al.,
2002). Today, the demand for clean water is increasing worldwide and the main challenge of
wastewater treatment is not only to produce clean water but it also support new developments
(Velan and Saravanane, 2013). The process of bioremediation depends on the metabolic potential of
microorganisms to detoxify or transform the pollutant, which is further dependent on accessibility
and bioavailability (Bhatnagar and Kumari, 2013). Remediation can be enhanced by the addition of
various microorganisms, called seeding or inoculation, to a polluted environment to promote
increased rate of biodegradation (Antizar–Ladislao et al., 2008). Phycoremediation is the use of
micro– or macroalgae for the removal or biotransformation of pollutants, including nutrients and
toxic chemicals from wastewater (Olguin, 2003; Mulbry et al., 2008). It is a novel, low cost and an
effective technique that uses simple and economical method as compared to the other conventional
treatments on the basis of nutrient removal (Elumalai et al., 2013; De La Noue et al., 1992).

Will Sewage Treatment Plants Have Effect On Water Birds '...
Will sewage treatment plants have effect on water birds' persistence and distribution?
Longji Deng, 100189430, Group 8
Introduction:
Anthropogenic climate warming has elevated the global temperature, and it has risen faster during
the last 40 years. There is no doubt that the temperature change has affected the biological process
of birds such as wintering, migration and breeding. (K Meller 2016) Also the increasing temperature
can cause a poleward geographical distribution.( Rachael H, et al, 2006)
It is certain that artificial ponds have positive effect on water birds ' breeding and migration as
ponds can provide more food and a safe space, these factors finally result in changing the
distribution. (Sánchez–Zapata J A, Anadón J D, Carrete M, et al. 2015) .
Sewage treatment plants are really common and important infrastructures as they play a significant
part in daily life. Almost every river people can find at least one plants. Due to they can be
considered as special artificial ponds, they may have effects on distribution and persistence of water
birds. According to some article, we find that they do have effect of shorebirds (Jose A. Alves, et al,

The Effects Of Phosphorus On The Great Lake
History of the Phosphorus Issue in the Great Lake
Back to the history, the eutrophication problem was first time concerned by public on Great lakes at
the 1960s, the Lake Erie was covered by algae as a result of over dumped phosphorus from the
sewage and other waste water, at that time, the Lake Erie was known as the "Dead Sea of North
America"(Fitzpatrick, J. J., and Di Toro 1999). The reason cause this problem can be concluded in 2
points, 1. the stresses of overfishing, 2. development of phosphorus–based detergents. At the end of
1960, the Canada and the United States have realized the penetrance of this problem and finally sit
on the table to sign an agreement that limiting phosphorus dumps to the Lake Erie, and plan to
control existing unstoppable algal growth. Because of the awareness of Canada and US government,
the concentration of phosphorus got a significant success. And this problem happened again during
the 1990s, but this time the reason why this happen is more complexly.

The team at Nut Island should be compared to the definition of a high–performance team. Nut
Island team members had different skills. They were able to get along and work together. They
really enjoyed working there even when they were up to their necks in sludge. Members worked
together to keep equipment working. They found ways to keep the plant running after senior
management stopped paying attention. Nut Island employees formed a highly creative team also.
When they ran out of chemicals they devised a plan to get more. Instead of calling management they
asked nearby residents to complain about the odor coming from the plant. They would have a new
supply of chemicals delivered to them a few days later. With the next two high–performance team
components, Nut Island begins to fall short. The team lacked a purpose and the values to make them
stick to that purpose. The purpose of the team was to clean up the harbor. They were supposed to
treat the sewage to make it safe to be dumped out in the harbor or to be turned into fertilizer. At
some point the team's purpose changed. They grew concerned with avoiding management and
continuing on their own. They still tried to do their job at the sewage plant, but their knew purpose

Importance Of Water Infrastructure
The basic physical and organizational structures that is used to transfer goods, people and
information is infrastructure. We all use infrastructure in our daily life like roads, water system at
our home, sewage system and much more.
WATER INFRASTRUCTURE: –The term "water infrastructure" includes water and wastewater
systems and includes water treatment facilities, water mains, distribution pipes, pressure reducing
stations, water meters, pumping stations, sanitary and storm sewers, sewage pipes, storm water
pipes, manholes, septic tanks and lift stations.
Importance of water infrastructure: Water and wastewater infrastructure is essential to keep our
waterways clean and our communities healthy. Water infrastructure of Canada is launching a new
water and wastewater Fund to provide communities with more reliable water and wastewater
systems.
As water infrastructure is one of the infrastructure which is directly related to health of human being
and animals as well as water is natural resource which needs to be conserved for future. If we have
well maintained water infrastructure in country, it will help a lot to our economy because it will save
our natural resource, people health and will also control water pollution. So, we need to maintain
water infrastructure time to time. We also need to upgrade it with new features that should separate
solid waste and water mixed with it. Than waste water should filtered, cleaned and recycled so that

Sewage Reclamation And Wastewater Reclamation
Introduction: Need for wastewater reclamation
Wastewater reclamation is the process whereby wastewater is treated using physical, chemical and
even biological methods, so that the effluent obtained can be used again, providing that it meets a
series of parameters which varies according to its use. The need for wastewater reclamation has
increased due to the ever increasing demand for water which has led to a rise in water stress both in
terms of quality and quantity of water (Gerke S., 2001). With wastewater reuse the water stress will
be alleviated. Constructed wetlands provide a cheaper and environmentally friendly means of
treating wastewater so that it can be reused (Kivaisi K. A., 2001). Constructed wetlands makes use
of the naturally ... Show more content on Helpwriting.net ...
T. C., 2006).
The wastewater reclamation can also be classified based on the constructed wetlands used for their
treatment. Constructed wetlands can be divided into two major groups, namely surface flow or sub–
surface flow. The latter can be further sub–divided into vertical or horizontal flow. There are many
more types of wetlands available but the ones above are the main ones currently in use.
Criteria for wastewater reuse Wastewater contains a host of physical, chemical and biological
components, it is therefore primordial to have standards which govern the usage of the treated
wastewater. Since the treated wastewater can have different uses such as for irrigation, in industries
or even aquifer recharge, different standards are required. The restricted agriculture irrigation means
that the crops irrigated must imperatively be cooked before consumption and therefore require less
stringent parameters. Another use which does not require stringent parameters is industrial cooling,
as there is less chance of humans coming into contact with the treated wastewater.
The origin of the wastewater is another determining factor in terms of criteria which must be met
before wastewater can be used again. For example, wastewater obtained from certain industries
(textile) may contain heavy metals which may be harmful to humans and other organisms alike

The Effects Of Sludge Sewage On The Waste Water Treatment
The usefulness of sludge sewage also known as bio solids in the environment can't be
overemphasized. According to Renner, millions of tons of sewage sludge is produced each year[1].
Land filling, incineration and land application are the possible options for the disposal of the bio
solids resulting from the waste water treatment. Approximately six million tons of treated sludge
produced annually in the U.S is applied to the farmland[6]. This method of disposal is favored
above the other methods because it is used as a form of amendment for the purpose of improving the
condition of the soil. The treated sewage sludge or bio solid is rich in nutrients like nitrogen and
phosphorus and organic content which make it useful as fertilizers to stimulate the growth of plants
as well as enhance and maintain productive soils[5]. In addition to the nutrients contained in the bio
solids, there is also the presence of a multitude of metals, contaminants and pathogens. This caused
the issue of the bio solids application in the agricultural lands to be a disputatious issue globally
right from the time the Clean Water regulations were enacted since the late 1980's[1]. Sewage
sludge or Bio solids are the byproducts of domestic and industrial waste water treatment processes.
According to Title 40 of the Code of Federal Regulations, Part 503, sewage sludge is regarded as the
solid, semi solid or liquid remains that results from the treatment of sewage produced industrially

To reduce the impacts of sea level rise on storm water drainage systems, pump stations can be used
to more effectively collect storm water runoff and direct it to the local waters. Enhancing storm
water pumping capacity reduces the likelihood of sewage backup due to sea level rise and flooding.
In addition, use of green infrastructure such as bioswales and rain gardens can reduce the impacts of
sea level rise on stormwater drainage systems. Bioswales are storm water runoff conveyance
systems that can absorb storm water runoff due to heavy rain. Bioswales filter the stormwater and
store the water, and hence, reduce the pressure on sewage systems during heavy rainfalls and
flooding. Rain gardens can be used as effective landscape elements to reduce storm water runoff.
When implemented as landscape components of different city facilities and buildings, rain gardens
can effectively reduce stormwater runoff and reduce the pressure on drainage systems under sea

Should the Thames Tideway Tunnel Go Ahead?

Joseph Bazalgette built London's current sewage system in the 1960's and, at the time of
construction, they stopped the spread of Cholera which was rapidly spreading amongst Londoners at
the time. The system also brought an end to the Great Stink of London. (BBC History, 2016)
Introduction to the Thames Tideway Tunnel
The construction of the Thames Tideway Tunnel is an eight–year project starting in 2016 with the
projected completion date in 2023. The tunnel is being constructed in order to address the issue of
London's overflowing sewer system. The current 20,000 miles of networked sewage pipes were
built in the 1860's by Joseph Bazalgette and they are failing to meet 21st century demands with
London's growing population and increasing levels of rainwater ending up in the sewers. The sewers
were designed so that rare overflows would be flushed into the river, however, at the time of
construction this only happened on average once a year and now it happens on a weekly basis
resulting in 39 million tonnes of raw sewage ending up in the River Thames every year. (BBC
News, 2014) (Super Sewer: An Introduction to the Thames Tideway Tunnel Project in London,
2016) According to Phil Stride from Thames Water, "It is absolutely not consistent for a world–

business, on one hand if you look at builders Display Homes you may choose your builder based on
the design of the home you have seen. This is not ideal as the builder may not be to your liking but
the design you like is tied to the builder therefore you cannot take his design to another builder. The
other option is to choose a builder based on friends and or relatives experience, then try to find a
design of home that the builder has that will suit your needs. This can be an easy process as most
builders have many designs to choose from. Quality and Specifications of the builder and their
Range can vary vastly from Builder to Builder. One Builder may include Special Finished Bench–
tops where another might have the Standard Laminate for the bench–tops. Obviously this will end in
a different price for the home. So all may not be as it seems with any price difference you need to

Biohazards of Sewage Sludge Essay
Wastewater can come from a variety of sources like homes, businesses, industries, runoff from
roads, lawns and fields and is treated by municipal wastewater treatment facilities (Product, cornell).
The solid material that remains after the treatment of wastewater is known as sludge (charac,
cornell). Sludge can be employed in many different ways, it can be used as a soil additive or
growing medium, sent to a composting facility, incinerated or landfilled (Char, cornell).
Biosolids are derived primarily from a combination of primary, secondary, and tertiary sewage
sludges. Biosolids do not contain the coarse grit and screenings removed from raw wastewater

These various routes or pathways of contact can result in either acute or chronic disease if the
exposure is high enough. For pathogens, the primary concern is acute diseases of a short–term
duration (i.e., gastroenteritis or flu–like symptoms), while for the various potential chemical
contaminants, risks are derived from chronic exposure via ingestion.
Pathogens that may be present in biosolids applied to land pose a disease risk only if there are routes
of exposure that deliver an infective dose. The principal means of exposure is through ingestion or
inhalation. Absorption through the skin is considered to be a minor route of exposure unless a field
worker suffers a cut or other puncture to the skin and is exposed. The degree of harm caused by
bacterial toxins varies with the mode of entry into the body.
It seems there is a correlation between the amount of biosolids applied and frequency of
contamination. A 1984 study showed that 22.4mg/ha applied to Sassafras sandy loam soil was the
upper limit to ensure that groundwater was not contaminated (Higgins, 1984). Doses below
22.4mg/ha of land are acceptable for the provision of nutrients to plants, while anything above
diminished the water quality to below American federal standards (Higgens, 1984). Heavy metals

Kalamazoo Water Reclamation Plant
Wastewater treatment systems are very important to providing clean, drinkable water to its
surrounding societies. These systems also help in the removal of contaminants in wastewater from
household sewage, runoff, domestic, commercial and institutional units. Processes include physical,
chemical and biological manipulation of contaminants to neutralize their effects on the human body
for consumption. There are three main types of treatment, primary, secondary and tertiary, all of
which have separate units and processes that flow in an organized manner to ultimately end up with
recycled potable water.
First in primary treatment the sewage is temporarily held in a quiescent basin where heavy solids
settle to the bottom while other contaminants such as oil, grease and lighter solids float to the top.
Commonly used procedures involve bar screens with washer compactors that remove a majority of
non–fine solid material waste. Other airs is added to settle solids for grit removal. Fine screens as
also used to capture the finer waste material that flows through the primary larger hole bar screens.
They can often have two different sizes of bar screens that help in removing as much sold material
waste before moving onto secondary treatment. The finer screens are used to capture plastics that

Oil Pollution in the Oceans
Oil
By the time the first oceanographers began widespread testing, the Industrial Revolution was well
underway and changes had already occurred. Since the industrial revolution, pollution has become a
major problem in this world. Pollutants cause damage by interfering directly or indirectly with the
biochemical processes of an organism. Some pollution–induced changes may be instantly lethal;
other changes may weaken an organism over weeks or months, alter the dynamics of the population
of which it is a part, or gradually unbalance the entire community. There are many forms of
pollution, which include natural and man–made. Oil is a natural pollutant that is spread by seeping,
dumping and spills.
Oil is naturally in the marine environment. Oil seeps have been leaking large quantities of oil into
the ocean for millions of years.
Because of our growing dependence on petroleum products, offshore drilling, and street runoff
carrying waste oil from automobiles, the amount of oil entering the ocean has increased greatly in
recent years. Every year more than 908 million liters of used motor oil finds its way into the ocean.
Motor oil that has been used is more toxic than crude oil or new oil because it has developed
carcinogenic and metallic components from the heat and pressure within internal combustion
engines.
Spills of crude oil are generally larger in volume and more frequent than spills of refined oil. Most
components of crude oil do not dissolve easily in water, but those

The filters consist of finely crushed coal, about one meter in depth, and sand, half a meter in depth.
This provides the final step in the treatment process.
Process flow – step 6 Chlorination/dechlorination Chlorine is added to the effluent to disinfect any
remaining microbiological pathogens; this takes at least half an hour. The effluent is then treated
with sulphur dioxide gas to remove excess chlorine, which would be harmful to the river ecosystem.
The effluent is then ready for discharge into the river.
Process flow – step 7 Solids separation and incineration The sludge and scum, removed in step 2 of
the process, are dealt with separately. The sludge is stored in a sludge holding tank where it is then
pumped to the centrifuge at a controlled rate. Polymers are added to the sludge to aid in the
thickening of the sludge during this process. Water is separated from the sludge by spinning in a
centrifuge to form a thick, muddy substance known as "cake", a process known as "dewatering".
The cake is then conveyed to the furnace where it is incinerated at 750–1000°C to produce Agri–
Ash. The scum, however, is stored in a heated tank to thicken it prior to its transfer to the furnace,
where it is also incinerated. Approximately 700,000 litres of sludge is treated each day to produce

bodies may be polluted and contaminated due to waste (e.g. sewage and chemical waste) generated
from different sectors of the economy. However, water pollution is not inevitable despite a country's
focus on economic growth, and in fact can be mitigated and controlled. A prominent example would
be that of Singapore. Singapore is a highly developed market economy, with the 3rd highest

Industrial wastewater is to be treated to specified standards regulated by the the Environmental
Protection and Management (Trade Effluent) Regulations before being discharged into a sewer or
watercourse. Furthermore, to ensure that these standards are met, industries which generate large
quantities of acidic effluent, such as the aforementioned photochemical industries, are required to
install devices to monitor the acidity of discharge into public sewers. The PUB has also installed a
system to monitor the amount of chemicals in the sewers. Laws have been enacted such that
offenders who do not meet such requirements and cause water pollution via improper disposal of
untreated wastewater will be fined and jailed for up to 3 months, acting as an effective deterrent.
Therefore, it is evident that water pollution is not an inevitable result of economic growth (caused
by the chemical industry), as demonstrated in the example of Singapore, and through proper
management and treatment of waste products, the fate of water pollution can in fact be controlled.
With economic growth comes an increased quality of life including one's living environment etc.
This brings about greater access to products and facilities which will culminate in an increased
consumption of goods and ultimately, a larger percentage of domestic waste. 6.5

The Wheaton Sanitary District is already using a state of the art monitoring system to track status
and record the measurement of the key plant operational equipment. The Supervisory Control and
Data Access (SCADA) system interfaced with the plant equipment provides, the operation team, a
real time data on the key components of the plant 's equipment. SCADA allows operational team to
open, close or adjust equipment parameters to archive maximum efficiency to meet the peak
demand. According to Russell and Taylor (2014), the size and complexity of the problem makes the
decision making often difficult. Further, the flow is controlled by a bottleneck, so any resource
should spend no time on non–productive activities, but must have material to work on to overcome

  • 2. Decentralized Wastewater Systems Regulatory And Economic... 6. Decentralized Wastewater Systems Regulatory and Economic Challenges During the last twenty years the USEPA has been evaluating decentralized wastewater treatment technologies as a reliable alternative for wastewater treatment. In 1997, the EPA submitted to congress its Report and subsequent documents endorsing decentralized wastewater treatment as a permanent long–term solution for wastewater treatment. The Report stated that adequately managed decentralized wastewater systems are a cost effective long–term option for meeting public health and water quality goals, particularly in less densely populated areas. The following is a summary the key components of the Report: The Agency (USEPA) provided an analysis of the benefits of using ... Show more content on Helpwriting.net ... Also decentralized systems are suitable for a variety of site conditions, including shallow water tables or bedrock, low–permeability soils, and small lot sizes. One of the additional benefits is that decentralized systems are also suitable for ecologically sensitive areas (where advanced treatment, such as nutrient removal or disinfection is necessary). Since centralized systems require collection of wastewater for an entire community at substantial cost, decentralized systems, when properly installed, operated and maintained, can achieve significant cost savings while recharging local aquifers and providing other water reuse opportunities close to points of wastewater generation (USEPA 1997). This benefit not only help alleviates the cost burden but also helps to improve the watershed conditions. The EPA Report also evaluated the obstacles that decentralized system may confront and ways to overcome the barriers were presented. The following are the most common barriers for the implementation of decentralized systems: Lack of Knowledge and Public Misperception. The perception of some homeowners, realtors, and developers that centralized systems are better for property values and are more acceptable than decentralized systems, even if they are far more costly, makes it difficult to demonstrate that properly designed and managed decentralized systems ...

  • 3. The Importance And Uses Of Wastewater Treatment Wastewater treatment is important in many ways. One reason that it is so important is because, at the plant, they water and other things as well. In the Middle Ages in London people had laws and regulations about waste treatment (O'Neill, 2013). Without wastewater treatment most species of animals would be extinct because the water in lakes and oceans would be polluted with human waste. Wastewater treatment is important because it keeps the Earth clean, it recycles more than just water, and it saves animal species from becoming extinct. Wastewater treatment keeps the Earth clean because without it humans would not have a steady source of drinking water. Back in the Middle Ages people were concerned about water treatment. People were heavily fined if they were caught dumping sewage into the streets. Instead, the people would take their buckets filled with raw sewage and dump it into nearby rivers and streams. This was extremely unsanitary. The bacteria, or decomposers, would break down the waste but there was so much that it took a long time.The people didn't know how disease was spread by waste. They thought that it was by its odors (O'Neill, 2013). People who owned larger houses had people come and clean their enclosed latrines. Even further back, the Aztecs had a waste system where all of the human waste would be used as fertilizer for their crops (Medina, 2014). Then the saprophytic bacteria would do the rest, consuming the decomposing matter. Saprophytic bacteria ... Get more on HelpWriting.net ...

  • 7. Building A Conventional Sewage Treatment Facility As in the case of rural non–point source pollution; urban areas are not likely to fix all contamination problems with one system. While it may be possible to build a conventional sewage treatment facility that can handle any storm condition it is not likely that this will ever be cost feasible to do. One type of larger combined sewage system that is being tried in several locations around the county where proper topography allows is the aquatic marsh system. In this type of system sewage still goes through the primary treatment of separation out the larger solids. Once these solids have settled out it move on to the secondary treatment where it undergoes another process to remove biochemical oxygen demand. This is done through introducing ...

It still is not treating the problem at its source. There are other options and systems that are in place to deal with urban pollution issues and flooding. Some example of systems that have the potential to mitigate urban at their source are implementing low impact development, installation of sand filters, infiltration trenches permeable pavers, storm water planters and green roofs. Low impact development (LID) is not a new concept but is still considered innovated when being discussed. LID is a storm water management program that manages storm water on site compare to conventional systems that pipe it off to a central treatment facility or directly into local water ways. Storms waters in the natural environment normally soak into the ground and are filter by the soils and vegetation. When areas are urbanized the water now running off taking contaminate with them. These waters can flow at fast rates causing increased flooding. The goals of LID are to lessen the impact storm waters on the natural environment, use land more efficiently, and help to lower cost.

  • 9. Negative Effects Of Urban Development On The Environment... Beaches are some of the most romanticized places on the planet, for good reason; however, the encroachment of humans onto beach and coastal habitats has resulted in several negative outcomes. At Santa Monica State Beach (and adjoining pier), one of the most popular and polluted beaches in California, the impacts of urban development, industry, and other man–made problems have caused mass pollution in the surrounding environment. The effects this pollution has on the coastal wildlife, water quality, and human health are catastrophic to the ecology and natural habitat of the beach. The beach began to decline in the early twentieth century with the construction of the Santa Monica Pier in 1909 after sixteen weeks of construction that on its own resulted in many tons of concrete being poured into Santa Monica Bay (City of Santa Monica, 2015). Over the next few decades land developers, and beach goers alike contributed a toxic combination of chemicals, bacteria, and trash that has resulted in Santa Monica Bay having several dead zones (Heal the Bay, 2015), which devastate the marine life population. Geology of Santa Monica Beach There is relatively little information on the natural geological history of Santa Monica State Beach; however, there is an explanation as to why. The beach was one of the very first beaches in California to be artificially doctored starting in the early twentieth century. The carousel manufacturer, Charles I.D.

  • 11. Effects Of Urbanisation On The Hydrology Of A Catchment Question 1 a) Explain the affects that Urbanisation can have on the hydrology of a catchment. Outline how SuDs can mitigate these impacts and explain the role and features of the following systems: Permeable pavements Swale Detention Ponds Urbanisation affects the hydrology of a catchment in various ways, it causes issues with the natural drainage of the environment by blocking stream channels and removing trees which help break the momentum of rain. Urbanisation creates a lot of surfaces that are impermeable which causes water build up, the water picks up pollutants and chemicals and these are dispersed into streams and rivers. Roads and pavements collect rainwater and channel it into waterways rather than letting it disperse into the ground, like it would if it had not had any human intervention. SuDs have been introduced within construction projects now in order mimic the natural drainage pattern of a specific area, these SuDs that are now being introduced are aiding urban developments in allowing surface water to be managed well without causing any impact on other sites. Permeable paving comes in a range of materials, it was designed to allow water through a surface that would have usually be impermeable, they are generally used on pathways, lawns and roads that only take light vehicle movements. They essentially reduce surface water run–off, which traps solids and filters some pollutants from the water, they also give urban trees the chance to grow to full ... Get more on HelpWriting.net ...
  • 12. Causes Of Water Logging In Dhaka WATER LOGGING PROBLEM AND DRAINAGE IN DHAKA IN RECENT years Dhaka City has been facing extensive water logging, especially, during the monsoon. Even without climate change, likely damage from waterlogging in Dhaka by 2050 is Taka 11,000 crore. In a changing climate with more intense rainfalls, the loss will be Taka 139,000 crores between 2014 and 2050. These damages can be reduced significantly to Taka 3,700 crores, if Taka 270 crores investment is made. The amount Taka 270 crores is equivalent to only 0.35 percent of the government's annual development budget expenditure for 2014–2015.(World Bank,2015).Problems that occur in the city are increase in water pollution, traffic congestion, air and noise pollution, solid waste disposal, black smoke etc. Inadequate drainage sections, conventional drainage system with low capacity and gravity, natural siltation, absence of inlets and outlets,indefinite drainage outlets, lack of proper maintenance of existing drainage system, and over and above disposal of solid waste into the drains and drainage paths are accounted for the prime causes of blockage in drainage system and water logging. During the last 25 years or so rapid uncontrolled urbanization has taken place in its capital city Dhaka. Substantial increase in built–up areas has taken place due to insensitive developments of areas through private land developers and real estate business (Tawhid, 2004).

By 1858 the stench from the raw sewage around and within the Thames was named the 'Great Stink'. It was a Civil Engineer named Joseph Bazalgette who proposed a plan of the creation of an underground network of tunnels, to put an end to the polluted river. His engineering feat has been improved and extended vastly but the Victorian Sewers still stand as London's primary sewer system. The sewers were designed to be a combined system meaning rainwater and waste were transported in the same manner. Bazalgette designed Combined Sewage Overflow (CSO) points along the Thames. The CSO's discharged the sewage and rainwater into the Thames after substantial rainfall, this prevented flooding the streets and houses. When designing the sewers, population increase was taken into consideration. (16) The underground system and factories were designed to treat and transfer sewage of up to double the population that was present when construction began. However the population of London almost quadrupled from 2.35 Million in 1850 (19) to 8.17 million in 2011(7). This drastic increase meant that the sewers were overloaded. The CSO's were overflowing with only 2mm of rainfall and on average discharging into the Thames around twice a week.

Phycoremediation And Environmental Pollution The rapid growth of human population and industrialization has lead to the environmental pollution and the world is facing problems with a wide variety of pollution (Kshirsagar, 2013). The release of wastewater poses serious environmental challenges to the receiving water bodies (De–Bashan et al., 2002). Today, the demand for clean water is increasing worldwide and the main challenge of wastewater treatment is not only to produce clean water but it also support new developments (Velan and Saravanane, 2013). The process of bioremediation depends on the metabolic potential of microorganisms to detoxify or transform the pollutant, which is further dependent on accessibility and bioavailability (Bhatnagar and Kumari, 2013). Remediation can be enhanced by the addition of various microorganisms, called seeding or inoculation, to a polluted environment to promote increased rate of biodegradation (Antizar–Ladislao et al., 2008). Phycoremediation is the use of micro– or macroalgae for the removal or biotransformation of pollutants, including nutrients and toxic chemicals from wastewater (Olguin, 2003; Mulbry et al., 2008). It is a novel, low cost and an effective technique that uses simple and economical method as compared to the other conventional treatments on the basis of nutrient removal (Elumalai et al., 2013; De La Noue et al., 1992).

The need for wastewater reclamation has increased due to the ever increasing demand for water which has led to a rise in water stress both in terms of quality and quantity of water (Gerke S., 2001). With wastewater reuse the water stress will be alleviated. Constructed wetlands provide a cheaper and environmentally friendly means of treating wastewater so that it can be reused (Kivaisi K. A., 2001). Constructed wetlands makes use of the naturally ... Show more content on Helpwriting.net ... T. C., 2006). The wastewater reclamation can also be classified based on the constructed wetlands used for their treatment. Constructed wetlands can be divided into two major groups, namely surface flow or sub– surface flow. The latter can be further sub–divided into vertical or horizontal flow. There are many more types of wetlands available but the ones above are the main ones currently in use. Criteria for wastewater reuse Wastewater contains a host of physical, chemical and biological components, it is therefore primordial to have standards which govern the usage of the treated wastewater. Since the treated wastewater can have different uses such as for irrigation, in industries or even aquifer recharge, different standards are required. The restricted agriculture irrigation means that the crops irrigated must imperatively be cooked before consumption and therefore require less stringent parameters. Another use which does not require stringent parameters is industrial cooling, as there is less chance of humans coming into contact with the treated wastewater. The origin of the wastewater is another determining factor in terms of criteria which must be met before wastewater can be used again. For example, wastewater obtained from certain industries (textile) may contain heavy metals which may be harmful to humans and other organisms alike (Salgot M., ... Get more on HelpWriting.net ...
  • 29. The Effects Of Sludge Sewage On The Waste Water Treatment The usefulness of sludge sewage also known as bio solids in the environment can't be overemphasized. According to Renner, millions of tons of sewage sludge is produced each year[1]. Land filling, incineration and land application are the possible options for the disposal of the bio solids resulting from the waste water treatment. Approximately six million tons of treated sludge produced annually in the U.S is applied to the farmland[6]. This method of disposal is favored above the other methods because it is used as a form of amendment for the purpose of improving the condition of the soil. The treated sewage sludge or bio solid is rich in nutrients like nitrogen and phosphorus and organic content which make it useful as fertilizers to stimulate the growth of plants as well as enhance and maintain productive soils[5]. In addition to the nutrients contained in the bio solids, there is also the presence of a multitude of metals, contaminants and pathogens. This caused the issue of the bio solids application in the agricultural lands to be a disputatious issue globally right from the time the Clean Water regulations were enacted since the late 1980's[1]. Sewage sludge or Bio solids are the byproducts of domestic and industrial waste water treatment processes.

Executive Summary Joseph Bazalgette built London's current sewage system in the 1960's and, at the time of construction, they stopped the spread of Cholera which was rapidly spreading amongst Londoners at the time. The system also brought an end to the Great Stink of London. (BBC History, 2016) Introduction to the Thames Tideway Tunnel The construction of the Thames Tideway Tunnel is an eight–year project starting in 2016 with the projected completion date in 2023. The tunnel is being constructed in order to address the issue of London's overflowing sewer system. The current 20,000 miles of networked sewage pipes were built in the 1860's by Joseph Bazalgette and they are failing to meet 21st century demands with London's growing population and increasing levels of rainwater ending up in the sewers. The sewers were designed so that rare overflows would be flushed into the river, however, at the time of construction this only happened on average once a year and now it happens on a weekly basis resulting in 39 million tonnes of raw sewage ending up in the River Thames every year.

This is not ideal as the builder may not be to your liking but the design you like is tied to the builder therefore you cannot take his design to another builder. The other option is to choose a builder based on friends and or relatives experience, then try to find a design of home that the builder has that will suit your needs. This can be an easy process as most builders have many designs to choose from. Quality and Specifications of the builder and their Range can vary vastly from Builder to Builder. One Builder may include Special Finished Bench– tops where another might have the Standard Laminate for the bench–tops. Obviously this will end in a different price for the home.

For pathogens, the primary concern is acute diseases of a short–term duration (i.e., gastroenteritis or flu–like symptoms), while for the various potential chemical contaminants, risks are derived from chronic exposure via ingestion. Pathogens that may be present in biosolids applied to land pose a disease risk only if there are routes of exposure that deliver an infective dose. The principal means of exposure is through ingestion or inhalation. Absorption through the skin is considered to be a minor route of exposure unless a field worker suffers a cut or other puncture to the skin and is exposed. The degree of harm caused by bacterial toxins varies with the mode of entry into the body. It seems there is a correlation between the amount of biosolids applied and frequency of contamination. A 1984 study showed that 22.4mg/ha applied to Sassafras sandy loam soil was the upper limit to ensure that groundwater was not contaminated (Higgins, 1984).

  • 35. Oil Pollution in the Oceans Oil By the time the first oceanographers began widespread testing, the Industrial Revolution was well underway and changes had already occurred. Since the industrial revolution, pollution has become a major problem in this world. Pollutants cause damage by interfering directly or indirectly with the biochemical processes of an organism. Some pollution–induced changes may be instantly lethal; other changes may weaken an organism over weeks or months, alter the dynamics of the population of which it is a part, or gradually unbalance the entire community. There are many forms of pollution, which include natural and man–made. Oil is a natural pollutant that is spread by seeping, dumping and spills. Oil is naturally in the marine environment. Oil seeps have been leaking large quantities of oil into the ocean for millions of years. Because of our growing dependence on petroleum products, offshore drilling, and street runoff carrying waste oil from automobiles, the amount of oil entering the ocean has increased greatly in recent years. Every year more than 908 million liters of used motor oil finds its way into the ocean. Motor oil that has been used is more toxic than crude oil or new oil because it has developed carcinogenic and metallic components from the heat and pressure within internal combustion engines. Spills of crude oil are generally larger in volume and more frequent than spills of refined oil. Most components of crude oil do not dissolve easily in water, but those ...

People do have a big effect on the problem within the city because they are so careless and do not think of the effects that their actions have on the environment. The 1900s led to the start of dealing with the contaminated drinking water throughout the city. The first step was constructing five filtration plants and using chlorine to treat the water. The Sewage system treatment plants in Philadelphia were constructed in 1950 to 1966 this consisted of the three plants to the right. The government regulations and funding are what determine the technologies and methods that we develop to treat and manage our water systems. Today we have for the most part dealt with the problem of contaminated water, but we still face some problems with bacteria. This especially affects the vulnerable part of our population like pregnant women and children and make them sick. This is a problem that runs city wide and if it does not get the attention that it needs we could see some very dire effects. Philadelphia over the years has improved its methods of cleaning up the water with the development of technology along with the knowledge gained from past experiences.

Polymers are added to the sludge to aid in the thickening of the sludge during this process. Water is separated from the sludge by spinning in a centrifuge to form a thick, muddy substance known as "cake", a process known as "dewatering". The cake is then conveyed to the furnace where it is incinerated at 750–1000°C to produce Agri– Ash. The scum, however, is stored in a heated tank to thicken it prior to its transfer to the furnace, where it is also incinerated. Approximately 700,000 litres of sludge is treated each day to produce 47 tonnes of dewatered solids. After ... Get more on HelpWriting.net ...
  • 39. Essay On Sewage Back Up Good evening, I just wanted to follow up with the topics covered during our meeting this afternoon and describe the events of the sewage back up. Saturday afternoon we noticed a smell on the 1st floor and upon investigation found that the 1st floor bathroom was flooded with approximately ¼ inch of water, the toilet was full of liquid and solid waste, and the tub had 2 inches of liquid and solid waste. We immediately called the emergency plumber and builder while placing towels and running fans to attempt to dry the area. In addition, we were told to notify the City of Austin about the issue. The City of Austin responded in approximately 30 minutes. They removed our sewer line cap to relieve built up pressure. City employees also used a ... Show more content on Helpwriting.net ... While making hotel arrangements, we were contacted by Servpro and arranged a 9 am appointment. The next morning, Servepro found water in the bathroom cabinet, the bathroom baseboards, and in one of the 1st floor bedrooms. Servepro set up 3 fans, 2 dehumidifiers, and scheduled a follow up appointment for 8/7/17 at 5:30 pm. The plumber arrived and went to our neighbors, but stopped never followed up with us. After contacting the emergency builder and Tiffany to determine what happened, the plumber called Linda around 5:00 pm. He stated that he would only come for an emergency, that we did not have an emergency situation, and that we would have to call back Monday to schedule a regular appointment. Today, 8/7/17, Mike and I spoke multiple times about the situation. Mike decided to stop by, assess the damage, and assist with contacting the right tradesmen. During the meeting, we discussed the following: The incident history What Servpro found The next steps in repairs – to include but not limited to baseboards, drywall, carpet, carpet pad, and the bathroom cabinet What Mike determined about the BSG power over ethernet issue and how it was not relayed to us Sending another plumber after hours to snake the toilet and tub Power washing the remaining waste out of our walk way

  • 41. Relationship Between a Country's Economic Growth and Its... Economic growth is the increase in the capacity of a country's economy to produce goods and services. As a means of development and urbanisation, and a reflection of wealth and the living standard in a nation, it remains a key focus of most governments. In this course of action, water bodies may be polluted and contaminated due to waste (e.g. sewage and chemical waste) generated from different sectors of the economy. However, water pollution is not inevitable despite a country's focus on economic growth, and in fact can be mitigated and controlled. A prominent example would be that of Singapore. Singapore is a highly developed market economy, with the 3rd highest GDP/capita in the world of $51,709.45 USD (2012). It has been ... Show more content on Helpwriting.net ... Industrial wastewater is to be treated to specified standards regulated by the the Environmental Protection and Management (Trade Effluent) Regulations before being discharged into a sewer or watercourse. Furthermore, to ensure that these standards are met, industries which generate large quantities of acidic effluent, such as the aforementioned photochemical industries, are required to install devices to monitor the acidity of discharge into public sewers. The PUB has also installed a system to monitor the amount of chemicals in the sewers. Laws have been enacted such that offenders who do not meet such requirements and cause water pollution via improper disposal of untreated wastewater will be fined and jailed for up to 3 months, acting as an effective deterrent. Therefore, it is evident that water pollution is not an inevitable result of economic growth (caused by the chemical industry), as demonstrated in the example of Singapore, and through proper management and treatment of waste products, the fate of water pollution can in fact be controlled. With economic growth comes an increased quality of life including one's living environment etc. This brings about greater access to products and facilities which will culminate in an increased consumption of goods and ultimately, a larger percentage of domestic waste. 6.5 ...

  • 43. Evaluation Of The Wheaton Sanitary District The Wheaton Sanitary District is already using a state of the art monitoring system to track status and record the measurement of the key plant operational equipment. The Supervisory Control and Data Access (SCADA) system interfaced with the plant equipment provides, the operation team, a real time data on the key components of the plant 's equipment. SCADA allows operational team to open, close or adjust equipment parameters to archive maximum efficiency to meet the peak demand. According to Russell and Taylor (2014), the size and complexity of the problem makes the decision making often difficult. Further, the flow is controlled by a bottleneck, so any resource should spend no time on non–productive activities, but must have material to work on to overcome the theory of constrain and the focus should be of automation efforts. SCADA does allow automation and the data collected from SCADA helps aeration optimization for scheduling which will ultimately reflect any capacity limitations. The new high energy turbo blowers save 30% energy to mix and aerate the tanks (Poole, Neighbors, Green, Baert, Sosnowski, and Wold, 2012) and the control flow provides additional saving with no additional capital cost. The real time monitoring and the dissolved oxygen (D.O.) measuring in the aeration tanks allows a development of a new plant control strategies to optimize the system performance thus consuming less power.
