City of Lawrenceburg
Solid Waste Study
By Ron Darden, Municipal Management Consultant
I.
Introduction and Acknowledgement
MTAS was requested to review the application of solid waste rates and fees; review
revenue and costs; and review the feasibility of using fully automated equipment for solid waste
collection. Solid Waste Director Gary W. Hyde and City Administrator William McLain are
commended for providing valuable data and information. MTAS Public Works Consultant John
Chlarson, P.E. and MTAS Technical Programs Manager Sharon Rollins, P.E. reviewed and
contributed to the report. CTAS Consultant Mike Stooksberry also contributed to the study. Ben
Bailey, CMI, provided cost estimates for equipment needs. Commercial is used to describe both
commercial business use and industrial use. The interpretation of the data is that of the author.

The city’s cost per ton for the collection and disposal of residential,
commercial and industrial waste is approximately $82 per ton. (Appendix 7)
Current revenues are not sufficient, even with the recent rate increases, to
cover the cost of collecting and disposal of solid waste.
While the city does use an efficient semi-automated collection system that is
capably supervised by Gary W. Hyde, it does not use a fully automated
system, which has the potential for significant savings.
The city pays approximately $18,000 annually for solid waste billing. The
city and county are billing the same customer base on separate billing
systems.
A review of customer billing indicated that some billing adjustments may
need to be made. It is not uncommon for billing registers to require
reconciliations from time to time. (Appendix 1)
All businesses do not pay a proper base rate for solid waste service based on
the type of service.
Residential service is paying 42.49% of the cost of collection and disposal and
commercial service is paying 57.60%. This includes what is being paid to the
city and to the county. Residential is using 32.54% of the service and
commercial is using 67.46% of the service. It appears that residential
1
households are paying for approximately 10% more than what they are
receiving and commercial is receiving approximately 10% more service than
they are paying for. Many communities subsidize commercial solid waste to
some extent in order to encourage growth, development and jobs.

Over a reasonable period of time, move the city’s solid waste service to a
fully automated commercial and residential system for collection of solid
waste. (See Appendix 6)
The city should bill commercial customers the amount charged by the county,
in addition to the city charges, and remit the revenue to the county on a
monthly basis. This would eliminate the need to operate two separate billing
systems.
Verify the accuracy of the solid waste master billing log on a regular basis and
assign someone to monitor it on a monthly basis. Revenue should be graphed
over time so that variations can be readily identified and investigated. (See
Appendix 1 for a review of revenue and cost)
Establish a uniform charge for all classifications of businesses operating
within the city.
Establish the commercial/industrial service as a true enterprise fund, whereby
charges pay for the service, and provide dumpsters and service upon demand.
Establish a solid waste equipment replacement reserve whereby uniform
annual deposits are made for the timely replacement of equipment. Such a
reserve would avoid annual budget fluctuations due to expensive solid waste
equipment purchases.
Increase the demolition cost from $32 per ton to $36.50, which is the current
landfill transfer station deposit charge.
III. Background
The City of Lawrenceburg provides for residential, commercial and industrial solid
waste collection and disposal. The city charges for services, with the exception of brush,
leaf, and trash collection and disposal, but the charges are not sufficient to pay the cost of
providing the service. Many cities do not fully recover such costs.
a. Residential and Commercial Waste Service
The city collects and disposes of approximately 67.5 tons of
residential/commercial garbage per day. Residential garbage is collected once per
week at curbside in 90 gallon containers provided by the city. The containers
have been in service for about 7 years.
2
The city has four (4) 20 cubic yard semi-automated garbage trucks and
one (1) 20 cubic yard semi-automated truck used part-time and as a reserve. The
city has two (2) additional trucks that are kept for spare parts.
Existing equipment includes:
1-1999 Model year- 20 CY truck
2-2002 Model year-20 CY trucks
2-2007 Model year-20 CY trucks
The residential garbage trucks are staffed with a driver and one collector.
The trucks are semi-automated equipped with flippers for lifting filled containers
and a cable system for emptying commercial dumpsters. Each residential
collection route also includes commercial and industrial service using cables for
moving and emptying dumpsters.
Each truck makes two (2) trips per day to the county operated transfer
station, which is located within approximately five (5) miles from collection
points. The trucks haul approximately 7-8 tons per load.
b. Brush, Leaves and Trash Waste
Brush, leaves and trash are collected with three knuckle boom
trucks/containers and deposited at the wood borrow pit located at the transfer
station. Residents are not charged for this service. M&S Wood Products charges
$4.00 per ton to receive, grind and remove the waste. The city pays fifty (50)
percent of the cost or $2.00 per ton and the county pays $2.00 per ton.
Approximately 3,063 tons per year are deposited at the facility.
c. Demolition Waste
The city accepts approximately 100 tons of demolition waste at the
transfer station each month. The depositor is charged $32 per ton. Some
commercial customers are billed for the use of the service on a monthly basis. The
revenue from this service is estimated to be $38,400 annually.
d. Roll-Off Container Waste
The customer is charged a $100 set up or drop fee for 3 days of service.
After 3 days the charge is an additional $10 per day. In addition, the customer is
3
charged $100 every time the container is emptied, plus $32 per ton of demolition
waste. If the waste is garbage waste, the charge is $100 for emptying plus $36.96
per ton. The city has five (5) roll-off containers and one service truck for moving
and unloading containers. (See Appendix 3)
e. Recycle Program
Lawrence County provides recycle containers at various locations within
the city. There is no charge for using the drop-off recycle program. The director
reported that the program generates approximately $205,000 in revenue to the
county per year.
IV. Billing
The city bills, through its utility system, for residential and commercial
garbage service on a monthly basis. The county bills each residence $54 per year
for county landfill cost. The county also bills city commercial customers based
on its rate schedule. (Appendix 1). The city charges $32 per ton for demolition
waste deposited at the transfer station. Residents are not charged for brush,
leaves, and trash removal service.
During the review for this study it was discovered that the master solid
waste billing log needs to be updated. Any additional revenues obtained from
updating the billing register could be deposited into a solid waste equipment
reserve for the purchase and replacement of future equipment. The city should
monitor the billing register on a monthly basis and graph revenue receipts in order
to identify significant variations and investigate. With proper monitoring of the
billing, additional rate increases should not be necessary in the current year,
assuming the general fund will cover any loss during the first six months of the
year.
The city pays approximately $18,000 per year for solid waste billing. The
city and county are separately billing the same customer base for solid waste
services on a monthly basis. The city should bill commercial customers
according to the county billing schedule, in addition to the city charges, and
forward county receipts to the county on a monthly basis. This would eliminate
the need for operating two billing systems.

V. Solid Waste Rates and Income
The city’s FY 2007-2008 budget totaled $1,123,453. The city increased
most commercial garbage rates effective January 1, 2008 in an effort to minimize
lost revenues in the general fund. The analysis of rates and revenues after the
January 1 modification of rates indicates that revenues will only total
approximately $1,027,215 for the fiscal year, assuming that the billing log
accurately reflects the current rates and service levels. (See Appendix 1 for an
analysis of solid waste revenues and costs). The city may experience a loss of
about $128,000 for the first six months of operation because rates were not timely
increased to coincide with budgeted expenditures.
Although MTAS recommends that the solid waste service be operated as
an enterprise fund, many Tennessee cities subsidize the solid waste service with
general fund revenues.
VI. Present Service Revenue and Expense Analysis
a.
Roll-Off Service
Revenue from the roll-off service is budgeted at $10,000 annually, while
expenditures are estimated to be $32,736.44. Approximately $22,736.44 is being
appropriated from the general fund to provide this service. (Appendix 3)
b. Brush, Leaf, and Trash Service
This service is being funded by the general fund and the expense is
approximately $200,749.89 annually, not including supplies, fuel, and other
operating costs. (See Appendix 4). Annually, 3,963 tons at a cost of $2 per ton to
the city is processed at the borrow pit partially operated by a private contractor.
This cost is not billed to customer users.
c. Residential and Commercial Garbage Service
The cost of the present semi-automated residential/commercial collection and
disposal service budgeted at $1, 173,600 annually. Approximately 32.54% of the
cost is for residential service and 67.46% for commercial service. The residential
service is generating 49% of the city’s revenue and the commercial service is
generating 51% of the city’s revenue. The revenue percentages do not yield a true
cost to the user. When the county’s charge for service is added to the city
charges, the total cost paid by residential households is 42.40% and the total cost
paid by commercial is 57.60%. Residential households are paying for about 10%
5
more than the service they receive and commercial customers are paying about
10% less than the service they receive. The city will need to access the
significance of such a variation in terms of the importance of commercial and
industrial growth and the creation of new jobs.
b.
Demolition Service
The city accepts approximately 100 tons per month of demolition waste at the
transfer station. The depositor is charged $32 per ton at the transfer station.
Some commercial customers are billed for the service on a monthly basis. The
customer transports the waste to the transfer station and the city does not incur
any expense for this service, except the expense for commercial use billing.
VII.
Residential and Commercial Solid Waste Options
The present semi-automated service provided by the city, including only direct equipment
and labor, cost approximately $548,950.83 annually. (See Appendix 2). A fully automated
service is estimated to cost $422,445.12 annually. It is estimated that the city could save
approximately $126,505.71 annually by using a fully automated service. (See Appendix 6
for an analysis of amortized cost of the present service, fully automated service, and
combination front load commercial-semi-automated service)
One of the options that the city may want to consider is converting the commercial
service to a fully automated front end loader system in about two years when the next two
garbage trucks are scheduled for replacement. And at which time the two additional garbage
trucks are replaced, replace them with fully automated equipment. It is estimated that using a
fully automated commercial service in conjunction with the present residential system will
cost approximately $469,733.77 annually. This cost is considerably less than the cost of the
present semi-automated system of flippers and cables. (Appendix 6)
In converting to an automated service, new equipment and compatible carts and
containers will be required. While the initial costs are substantial, the costs amortized over
the period of useful life of equipment and containers is lower than the amortized cost of
similar equipment for the present semi-automated service. (Appendix 5) The city’s
administration would be challenged to place displaced workers, approximately 4 when full
automation is achieved, in other jobs within the city.
VIII. Commercial and Industrial Container Needs
The present style dumpsters, having an estimated useful life of 10 years, which are
presently moved and emptied by a cable system using residential trucks, cost approximately
$377,283.00. This cost is presently paid by commercial and industrial businesses. Commercial
front load dumpsters cost approximately $272,070. A savings of approximately $105,213 could
6
be realized from using commercial front load dumpsters as opposed to the current system. The
commercial front load system option provides that the dumpsters would be provided by the city
upon demand and the commercial customers would pay the cost of the commercial service,
which is projected to be less than the present cost when fully automated. The amortized cost of
commercial dumpsters with a life of 8 years service at 5% interest would be $42,095.00
annually. The amortized cost of the present system of dumpsters provided by commercial and
industrial customers is estimated to be $58,374.00 annually. A commercial front load system
would be a significant benefit for business and industry, as well as to the city. (See Appendix 5
for container needs)
IX. Residential and Commercial Usage
Each garbage truck deposits at the transfer station 2 times per day. A 20 CY truck hauls
approximately 7 to 8 tons when loaded. Using 4.5 trucks and 9 trips per day at 7.5 tons on each
truck, the deposits amount to approximately 67.5 tons per day of residential and commercial
garbage.
The national average pounds per year per household are 2,343 pounds. With 4,875
residential households, the usage is 11,422,125 tons per year or 5,711.06 tons per year of
residential garbage.
By using 67.5 tons of residential garbage per day on a weekly basis, 17,550 tons per year
of residential and commercial waste is collected and disposed. The combined total of 17,550
tons per year less the residential tonnage of 5,711.05 tons per year gives the commercial usage of
11,838.94 tons per year.
From this analysis, the residential household is using 32.54% of the service and the
commercial business is using 67.46% of the service.
X. Equipment Needs Analysis
o Residential –Semi-automated truck collecting 500 units per day with 5,165
customers would require 10.22 days or 2 trucks.
o Residential-Fully-automated truck collecting 750 units per day with 5165
customers would require 6.87 days or 1.374 trucks. Two trucks would be
required. One would be part-time and serve as a backup.
o Commercial front load truck-using 9 pickups per hour or 72 pickups per day, a
truck can empty 360 dumpsters per week. With 698 dumpsters to be emptied
weekly, 2 commercial front-end trucks would be required. (See Appendix 1 for
dumpster count).
XI. Annual Cost per Ton.
7
The average cost per ton for collection and disposal of solid waste in the City of
Lawrenceburg is $81.93 per ton. (See Appendix 7)
