Municipal Government &
Transfer Station
Problem: A municipal government has agreed to provide once per week waste collection services to a
new residential community of 25,000 people. The city council has hired you to make a preliminary
assessment to determine if they should build and operate a transfer station to support the collection.
For the initial analysis, assume that the community does not have a recycling program. Here is some
of the initial data that the municipal engineer has collected.
* The round trip distance from the residential community to the landfill is 40 miles.
* The size of the residential garbage truck that collects waste from the community is 30 cubic yards.
* The round trip distance from the proposed site of the transfer station will be 45 miles.
* The garbage truck is capable to compact the refuse to 700 lbs./yd3.
* A long haul truck is capable to transport 25 tons of compacted waste per trip.
* The transfer station has a fixed operating cost of $15/ton.
* The cost to operate the garbage truck is $1.50/mile.
* The cost to operate the long haul truck is $0.75/mile.
(a) Would you recommend to the city council that a transfer station should be built and operated?
Show all work on how you came to your answer.
* The United Nations estimates waste generation rate is 4.8 lbs. per person per day.
(See page 39 of the textbook)
(b) If the community operated a recycling program, would this change or support your
recommendation to the city council? Show all work on how you came to your answer.
* Total recycled municipal waste is 33.2% of generation.
Solution
:
(a) We will use the estimated waste generation rate of 4.8 lbs. per person per day in this calculation.
Step 1
Residential waste generated = 25,000 people x 4.8 lbs. x 7 days = 840,000 lbs. or 420 tons
person/day 1 week each week
Step 2
Calculate the waste collected in each truck:
30 yd3 x 700 lbs. = 21,000 lbs. of waste collected per truck
truck yd3
Step 3
Calculate the number of trucks needed:
840,000 lbs. = 40 trucks (round up)
21,000 lbs./truck
Step 4
Determine the cost to travel to landfill by garbage trucks:
40 trucks x $1.50 x 40 miles = $2,400 per week
week mile
mailto:[email protected]
https://mycsu.columbiasouthern.edu/student/forms/courses/math-center-request/
Step 5
Calculate the number of long haul trucks based on residential waste generated:
420 tons = 17 trucks (round up)
25 tons per truck
Step 6
Determine cost to travel to transfer station by long haul trucks:
17 trucks x $0.75 x 45 miles = $573.75
mile .
Hy-Tech Cleaning technology for Solid Waste Management by Using Micro-Control...IJERA Editor
Solid waste management nowadays is an important environmental issue in country like India. Statistics show that
there has been substantial increase in the solid waste generation especially in the urban areas. The impact
assessment environment management tool makes a relationship between two factors- the amount of land required
to dispose per capita generated waste. To give a brief description of the project , the sensors are placed in the
common garbage bins placed at the public places. When the garbage reaches the level of the sensor, then that
indication will\ be given to ARM 7 Controller. The controller will give indication to the driver of garbage
collection truck as to\ which garbage bin is completely filled and needs urgent attention. ARM 7 will give
indication by sending SMS sing GSM technology.

A VISION FOR FUTURE SLUDGE MANAGEMENT IN ALEXANDRIA ( Egypt)Helalley Helalley
After full operation of secondary treatment at the East and West treatment plants, the future production of sludge from these plants and from Amriya and Agamy secondary treatment plants in addition to the rest 14 secondary treatment plants all around Alexandria is expected to exceed than 1200 m3/d by 2015 thus the capacity if the sludge disposal site should exceed. Therefore, the future sewage sludge management represents a critical environmental issue in Alexandria, this management includes sludge dewatering, handling, transportation cost to the disposal sites and the final product marketing.
As the capacity of Alexandria sludge disposal system will be limited by the increase in sludge production and the current management system, there is an immediate need to investigate ways to establish a future management system and to demonstrate successful operations at higher sludge producing rates.
Currently, Site 9N the sole disposal site in Alexandria include a composting plant established when the site was initially developed as a dedicated disposal area for sludge. Consequently, land spreading of the sludge on the dedicated disposal area has ceased and all of the current production of raw sludge is now being composted using the turned windrow technique.
The present study aims to evaluate the current efficiency of the sludge management system and adopt a future vision for the Alexandria sludge system and recommend modifications to protect public health and environment.

proposal to convert the umapad sanitary landfill into a transfer station
1. PROPOSAL TO CONVERT THE USAGE OF THE MANDAUE CITY
SANITARY LANDFILL INTO A TRANSFER STATION AND CONTRACT
OUT FINAL DISPOSAL SITE FOR MANDAUE CITY RESIDUAL WASTE
Prepared by:
ENGR. RICARDO D. MENDOZA, MPA
SWMO-Director
2. I. RATIONALE
Mandaue City is one of the fastest growing industrial hubs in Metro Cebu. Through the years past
ever since the city was declared as highly urbanized and industrialized in 1991, the population and the city’s
income grew exponentially. Due to its strategic location, people migrated to the city as well as commercial and
industrial establishments opened their doors in the city. Due to such influx, the city has significantly benefited
from industrialization and commercialization putting at risk its precious natural resources as population grew at
very fast pace.
In light of this, the city faces a daunting task to safeguard its environment preserving its social,
economic and industrial advances. The city’s resources such as creeks and rivers and other vegetation are
adversely affected due to its urbanization and industrialization. Waste produced from the migrants as well as
commercial and industrial establishments has increased exponentially.
The City has rehabilitated the dumpsite in Barangay Umapad into a sanitary landfill where
scavengers converge to collect recyclables that are sold to independent traders unfortunately a 1 hectare
sanitary landfill cannot cope up the increasingly volume of garbage in which the city has generated. The
dumpsite is a host to all types of garbage be it biodegradable, recyclable, special, or residual. As the City has
not have an alternative site for final waste disposal, the Umapad Sanitary Landfill continues to be patronized
with the hope that the volume of wastes to be thrown there will be reduced through the material recovery
facilities and segregation at source.
3. II. STATEMENT OF THE PROBLEM
The purpose of this proposal is to justify the conversion on the usage of the Mandaue City sanitary
landfill into a transfer station and contract out final disposal site for Mandaue City residual waste. Specifically, the
following sub-problems were taken into consideration:
1. What are the main factors for the increasing of solid wastes generated by the City?
2. What types of wastes and quantities are generated by the City?
3. What is the estimate cost in operating a dumpsite and operating a transfer station?
4. What are the estimated waste volumes generated per day;
a. In operating a dumpsite? and,
b. In operating a transfer station?
4. III. COST
ESTIMATE ON OPERATING A DUMPSITE
For a 1 hectare sanitary landfill to operate considering the daily activities: spreading and compacting solid waste
in layers with repeated passages of the landfill equipment to maximize compaction to approximately 0.60 m or 2

9. V. COMPARATIVE ANALYSIS
OPERATING A LANDFILL TO OPERATING A TRANSFER STATION
Industrialization and urbanization are the main factors for the increasing solid wastes generated by
the
City,
which
hosts
major
industries
such
as
food
processing, furniture, metal/steelworks, construction, textiles, bottling, automotive/electronics repair and
manufacturing, chemical, cottage, agriculture, and others.
For this justification, planning involves the collection of information on type, amount, generation
rate, trips, fuel allocation in each trip, monthly maintenance, type of equipment/truck, total amount of tons and
characteristics of the wastes to be accepted for landfilling. Acquisition of this information is a prerequisite to an
efficient and effective development of a transfer station. Indeed, it should be noted that the underlying assumption
is that reduction and recycling are the preferred courses of action, and that transfer station is intended for the
residue left after recycling.
10. At present time, the volume of garbage disposed in Umapad dumpsite has been increasing due
to non-compliance of segregation at source. In this case, if the location will operate as a landfill in three
years’ time it will become a mountain of garbage. The mere fact that the location itself is intended to be a
commercial area. In effect, it will reduce the value of property considering the negative impact of
environmental issues and concerns. In converting the landfill into a transfer station, the volume of garbage
will not be mounted due to transferring the waste into a private landfill.
In the barangay level, based on the data we monitored and gathered, it shows that at present
there are only 5 functional Material Recovery Facility (MRF), 9 non-functional and the 13 barangays don’t
have its own MRF. Upon converting the landfill into a transfer station, all barangays will be given an MRF at
the said location and can be easily monitored.
11. The present condition of our dumpsite during bad weather is that our garbage trucks cannot dispose
waste due to the condition of the access road of the area and also if the equipment is not functional, the
operation will be hampered. This will greatly affect the collection of garbage at the barangay level. Access roads
from the public road to the site should be accessible in any weather condition. The roads should be designed to
support the anticipated volume of wastes.
Consequently, in operating a sanitary landfill, it will entice a large amount of cost on having for soil
cover daily not considering the volume of garbage that will generate. While operating a transfer station the cost
will only the tipping fee and fuel cost for transport. But if we will have a final sorting and make sure that waste to
be disposed will be purely residual it will reduce the cost of waste.
12. B. CONCLUSION
As the population of the City increases, the pile of solid waste that households generate gets higher
and higher. Unfortunately, the amount of space available in Umapad Dumpsite cannot keep up with the increased
volume of wastes dumped, and all that trash generated from 27 Barangay Local Government Units (BLGUs) have
to go somewhere.
Based on the data we monitored and gathered for this justification, it safely be concluded that for half
hectare of sanitary landfill to operate considering the daily activities: spreading and compacting solid waste in
layers with repeated passages of the landfill equipment to maximize compaction to approximately 0.60 m or 2 ft.
Placing daily soil cover at least 6 inches over the waste at the end of each day’s operation.
The cost estimate in operating a dumpsite in every three days for half hectare is 179,280/day; the
projected estimated amount that may cost if we put a soil cover isPhp 1,792,800/month . For its equipment cost
(Bulldozer) and its labor (Driver & Helper) is Php 13,780.00/month.
Grand total for operating a dumpsite is Php 1,937,080.00
While the cost estimate in operating a transfer station is Php 1,365,000/months. For the fuel
consumption in transporting for 13 trips from Umapad Dumpsite to Consolacion Landfill, it estimated to Php
11,310/day per trip and with its labor (driver & helper), projected amount to Php 339,300/month. The equipment
cost will be , Php 26,100/month for its labor (driver & helper) is Php 13,780.00/month.
Grand total for operating a transfer station is Php 1,755,490.00.

18. C. RECOMMENDATION
People living in Mandaue City throw away household rubbish every year. All these wastes have a
huge impact on the environment. The amount of wastes that are creating is increasing and the nature of waste
itself is changing. This means waste now contains an increasingly complex mix of materials, including plastics,
precious metals and hazardous materials that are difficult to deal with safely.
Based on the foregoing data gathered and conclusions, the following recommendations are hereby
given:
1. The usage of City’s Sanitary Landfill into a transfer station represents an opportunity to recover resources. It
offers an appealing solution looking to hold the wastes generated by households in the City.
2. We understand that the Barangays are individually responsible for the waste collection. To make it expedient,
the Mandaue City government should adopt the conversion of landfill into a transfer station so that the waste
collection will be centralized. So as, the volume of garbage will not be mounted due to transferring the waste into
a private landfill. And upon converting the landfill into a transfer station, all barangays will be given a Material
Recovery Facility (MRF) at the said location and can be easily monitored.
19. 3. Maintenance of access roads at the site should be conducted on a continuous basis.
Roads should be inspected and repaired frequently. Lack of proper road maintenance
leads to equipment damage, unnecessary delays in operations, and safety problems. So
as in converting the dumpsite into a transfer station, we have to make sure that we will
provide a concrete and passable access road and assigned well-conditioned equipment
for transferring the residual waste to the assigned city transport truck.
4. Landscaping in transfer station would suffice for it creates green buffer zones to
increase liveability and a beautiful environment to decrease your stress levels. Adding
trees, shrubs, flowers, grasses and plants to the landscaped areas can attract wildlife
such as birds. It offers substantial environmental benefits because it reduces air pollution
by absorbing carbon dioxide and releasing oxygen. Having it landscaped, it can also
reduce noise pollution by blocking out surrounding noises and heat reduction.
By this, the City government can promote this one of a kind environmental friendly
transfer station to other LGUs where they can visit, conduct educational tour and they
can also replicate this to their respective city/municipalities.
