Re-using and recycling water has the potential to significantly reduce water usage, especially in urban areas. Treating and disposing of water after only one use is wasteful, as water can be filtered and reused for multiple purposes like irrigation, toilet flushing, and some drinking water. While water recycling provides environmental and economic benefits over alternatives like desalination, it also faces social and cultural hurdles as some find the idea of recycled water, especially from black water sources, unappealing. An comprehensive evaluation of benefits and drawbacks across multiple dimensions is needed to determine the best solutions for sustainable water management.
Each and every process for our daily needs require either direct or indirect usage of water.

Water is the basic need of life on the earth. The useful freshwater resources are less. It is the time to save, conserve and manage the water resources for next generations.
Water is the “invisible utility”, whose usage patterns are too often overlooked by companies as a cost of doing business. Water bills can account for as much as 20% of a buildings’ utility cost and upwards in process applications. Compared to other countries, Canadian water prices are well below average. The cost of water is likely to rise as watersheds are depleted, water conservation and efficiency standards are legislated, and municipal governments increase rates to fund repairs to aging infrastructure. To reduce water utility bills, building owners must find ways to limit their consumption without sacrificing occupancy comfort.
Smart use of Water and Energy in domestic householdsMrinmoy Majumder
This presentation proposes a new method to optimally utilize the water supplied to domestic households in such a manner that both water and energy used in running the supply pumps can be conserved. The proposed "sensor based network of sub-tanks" can help to reduce the wastage of sufficient amount of water and the introduction of purifier at the inlet can save energy which is otherwise wasted in over running a corroded water pump.

Recycled water is wastewater that has been processed through primary, secondary and tertiary treatment and disinfected with chlorine.
Man-made water recycling, also known as water reclamation or water reuse, centers on using treated wastewater.
Recycled water, also known as "greywater," derives from residential water uses such as the bath, shower, washing machine, sink etc.
Across the globe, 2 out of 10 people do not have access to safe drinking water, and in the U.S., many states face water shortages and droughts.
In the U.S., we spend billions of dollars treating water to drinking water quality when we use only 10% of it for drinking and cooking, then flush most of the rest down the toilet or drain.
All water is recycled and reused as a part of natural water processes such as the hydrologic cycle.
Recycling wastewater can extend water supplies, improve water quality, reduce discharge and disposal costs of wastewater, and save energy.
Using recycled water reduces reliance on scarce and expensive surface water. It can also minimize groundwater overdraft and reduce discharges of treated wastewater into rivers and oceans.

Domestic Liquid Waste Purification and Recyclingijtsrd
Rapid industrialization and urbanization subsequently brought many variations in the environment and ecosystems in the world, as a result there is proportionate increase in the domestic waste generation in India. Growth of urban areas, increase pressure on local water supplies. Already, usage of groundwater aquifers by over half of the world population are being over drawn, as a result, it is no longer advisable to use water once and dispose of it, so reuse and recycling of water is must. For formulating a sustainable water policy, a reliable source of water such as Recycled water should be taken into account. Recycling and reuse of water should be made obligatory to reduce the huge pressure on demand of fresh water. Waste water from water intensive activities should be recycled and reused and make the reclaimed water available for use in the secondary activities either within or outside the locality, resulting in saving lot of water. The total quantity of water used by the domestic sections is much less than that for irrigation. However, the liquid waste released from the domestic sections has a huge amount of pollutants and is discharged at specific disposal points. Thus, the purification of liquid waste generated from domestic projects is of much more importance. The quantity of organic matter in liquid waste is of great importance due to its polluting potential. The availability of oxygen for fish and other aquatic organisms can be reduced due to direct discharge of this matter into water bodies. Here comes the Purification and Recycling of domestic liquid waste into picture. Water recycling, also referred to as water reuse or water reclamation, is an effective method of treating captured or conveyed wastewater and redistributing it to benefit other water dependent applications. Unlike traditional approaches where water is merely discharged as waste after use, water recycling provides a reliable local water supply, helping improve water conservation, cut energy use and costs, minimize diversions from local water bodies, and prevent water pollution 1 . The objective of this work is to study about domestic liquid waste i.e. sewage its purification and recycling. With the help of some case studies this paper gives information about the processes and various units of purification and how the waste water is recycled after getting treated and its application.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

Water Recycling
Re-using and recycling water has huge potential to alleviate our water needs, especially in urban areas.
Water used in households and businesses is typically treated and disposed of (e.g., pumped out to sea) after
just one use. By re-using water, we can use it for multiple purposes before it is discarded. Water recycling in-
volves filtration and re-use, instead of just disposing it after one use. Recycled water is also called ‘reclaimed’
water.
Greywater is water that has been used in bathtubs, washing machines, showers, and bathroom sinks. Grey-
water can be re-claimed and used in gardens and to flush toilets. It’s estimated that 60 to 65 percent of
the water used in homes can be re-used!1
Water re-use can be as simple as saving water used for washing
dishes for plants in the garden.
Irrigating lawns and parks is a common use for reclaimed water. Reclaimed water can also be used on farms.
In Delaware, reclaimed water has been used for irrigating crops since the 1970’s. A 2007 study estimated
that over 20 million hectares—about the size of Nebraska—of farmland are irrigated with reclaimed water,
and this is expected to increase with greater demands for food.2
Water that has been used to flush toilets (referred to as black water) can be recycled by filtering and sanitiz-
ing the water on site, using a method called reverse osmosis. The average American uses 24 gallons of water
a day just for flushing toilets. If water recycling systems were implemented for every toilet, this could save
5.8 billion gallons of water per day!3
In Orange County, California, wastewater is filtered and then put back into underground aquifers used for
drinking water. Orange County is one of the few places where residents drink recycled wastewater.4
Unfortunately, many people may reject drinking water that has been recycled from toilets. Recycling black
water would require potentially costly changes to indoor plumbing for filtration. But when compared to de-
salination, re-using and recycling water is typically cheaper and less energy intensive.5
