Introduction
*urMse nf thft Slurry
'an of the state's ongoing responsibility is to
cquire financial and technical information
bout its communities. The information ac-
quired from this user charge survey allows the
State to monitor the ability of its communities
3 achieve financial self-sufficiency for waste-
water treatment operations. There is an espe-
ially strong need for the state to look even
nore closely at user charges since local munici-
alities will be financing their future wastewa-
;r construction without the assistance of fed-
ral grants. The future success of wastewater
ollution control in the State will depend on the
bility of local communities to maintain finan-
ially self-sufficient wastewater treatment
perations.
)o communities have healthy user charge
/stems that provide adequate revenues to
ipport operations and debt repayment? To
iswer this question and plan for the future,
tate and local officials must know where com-
munities stand in running self-sufficient waste-
ater systems.
0	obtain information on the financial solvency
f its communities, the State of Tennessee
ndertook a survey of user charges following
le procedures given in the United States Envi-
)nmental Protection Agency's publication
poking at User Charges: A State Survey and
sport (EPA 430/09-87-0008). The survey's
1	questions, although deceptively simple,
:nerate a wealth of information on residential
lit costs. A copy of die survey form is pro-
ded in Appendix A.
csponses on demographic and utility charac-
ristics were used to calculate units costs and
ows, examine economic impact and ensure
did comparisons between communities. Costs
ata provided the basis for comparing user
charge systems and the costs of operation,
maintenance, and capitalization. Revenue ques-
tions allowed the examination of whether the
systems were recovering enough money to
operate in the black.
Not all respondents answered all the survey
questions. This resulted in different sample
sizes being used for the various analyses. The
revenue and cost analyses were based on data
from 18% of the state's wastewater treating
communities.
Organization of Report
This report is divided into six sections to evalu-
ate the financial self-sufficiency of municipal
wastewater treatment operations:
I. Covering the Costs of Operation
H Unit Costs by Treatment Level
m. Average Annual Total Costs per
Household and Sewer Service Charges
per Household
IV.	Ability of Households to Cover Costs
V.	Debt Burden Without Grant
Contribution
VI.	Summary Findings
A summary table of each community's re-
sponses to the survey is presented in Appendix
B.
L Covering Costs of Operation
The most basic question is "Are sewer service
charges adequate to cover the costs of operation
and to achieve clean water goals?" This analy-
sis shows the ratio of revenues to costs. For
communities where specific wastewater reve-
nues are not adequate to cover total treatment
costs, i.e., the ratio is below 100%, the commu-
nities should reassess their user charge systems
and other sources of revenues to ensure proper
funding.
In this analysis, 68% of the communities

HL Average Annual Total Costs
per Household and Wor Service
Charges oer Household
The average annual total treatment costs per
household and sewer service charge for a typical
household using 5,000 gallons per month serves
as a basis for later analyses including the per-
centages these represent of median household
income. Here, the data has been arrayed to show
the distribution by treatment levels.
The distribution of cost per household in similar
for secondary and advanced treatment. Most
communities experience costs in the $100 to
$400 range, though some experience much
higher costs.

TV Ahilitv of Households to Cover Costa
Average cost per household as a percentage of
median household income can be used to indi-
cate whether the cost of wastewater treatment is
becoming burdensome for community residents.
These data can also be used to predict the ability
of the community to generate more revenue by
increasing its sewer service charges.

V. Debt Burden Without


Grant Contribution
The effect of grant funding on capital costs ait
examined by making adjustments to the debt
financing cost figure (as reported in the sur-
veys) to reflect "total" costs of capital without
Federal or State grant assistance. This roughly
determined the impact of grant assistance on
community treatment costs.
This analysis showed that the average debt
financing costs for advanced treatment would
have increased from $1.46 to $2.07 per 1000
gallons, while it would have increased from
$1.78 to $2.79 for secondary treatment. In this
analysis, grants reduced the average treatment
costs from $4.05 per 1000 gallons to $3.10 or
23% for secondary and advanced treatment
systems.

Dear (State Name) Community Official,

The budget problems you've faced in paying for community services will
probably increase In the future. This means your local residents and industry
must pay more for wastewater treatment. Your challenge will be how to raise
money to meet your current and future wastewater treatment needs. The
Information requested 1n the attached survey can help you meet this challenge.
STRIKING A BALANCE
As you know, every community needs to continuously examine Its wastewater
costs and revenues to make certain they balance. The results of this survey
will help you decide if your current service charges are adequate for
operating, maintaining, and improving your wastewater treatment facilities.
HOW DO YOU COMPARE?
The information you and others provide will be analyzed to show how much
communities in the state pay for wastewater service. You'll be able to
compare your community's costs with others. If you return this survey to us,
we'll send you a copy of the survey analysis report.
DO YOU HAVE QUESTIONS?
Instructions are attached to help you answer the survey questions. To
answer some of the questions, you may need to Involve various people In your
organization who know about the special aspects of your wastewater system.
Even if you or others don't know the exact answers to all the questions,
please use your best estimates and return the survey to us by (date). Please
feel free to call (name of contact) at (telephone number) 1f you have any
questions. The survey sltould be returned to (name of contact and address).

INSTRUCTIONS FOR COMPLETING SURVEY
These Instructions Include Information plus directions to helo vau
some of the questions. If something does not fit your situation mJ!!1 l!
best as you can and explain the problem or call the number shown In tha
letter for more help.	®
QUESTIONS 1-6
There are several possible sources of information to complete Questions 1-6.
Use the most current source that corresponds best to your wastewater
facility's service area. Sources for data Include the census, surveys
conducted by a regional planning agency, etc. In all cases, provide the best
Information you have; give us your best estimate if actual numbers are not
avail aoTT
1. Households. This should be the total number of households (residential
customers) serviced, not the number of people or population. (Residential
apartment buildings sliould be treated as equivalent dwelling units.)
2. Median Household Income. This should be the most recent census value or
current estimate. Your local Bureau of Census, Data User Center, can
provide this Information.
3. Current Average Flow Treated. This value represents flow from all
sources. Flow should be reported 1n gallons per day. If your flow is
calculated 1n cubic feet per day, multiply the flow by 7.481 to convert it
to gallons per day.
4. Average Wastewater Flow Per Household Per Day. Calculate as follows:
gallons daily . number of residential dally flow per household
residential flow 7 customers	a (gallons per day)
Your figure for gallons daily residential wastewater flow might come from
your water supply department or your billing office. The wastewater flow
figure should include an adjustment for 1nf1ltrat1on/1nflow.
QUESTIONS 7-11
Cost and revenue Information you provide in Questions 7-11 should Include all
parts of the wastewater system: collection (sewers, pumping stations), the
treatment plant, and disposal (outfalls, sludge disposal).
7. Annual Costs. This number should include annual "operating costs,"
"maintenance costs," "replacement costs" for wastewater collection and
treatment* and any charges from Regional systems. (It OOES NOT Include
the costs ofwastewater loans and bonds, or depreciation).
A4

-------
Operating costs Include labor, materials and supplies, utilities, and
overhead (such as office rent).
Maintenance costs Include preventive and corrective maintenance.
Rep!acement costs Include costs to maintain but not to extend the useful
life of the facilities (like pumps and motors).
8. Equipment Replacement. This question 1s Intended to determine what
percentage of the operating costs you Included in Question 7 are being put
aside to maintain but not extend the useful life of the facilities (Tike
pumps and motors).
9. Costs of Loans or Bonds. This number should include all principal and
interest payments you are making annually to pay for your wastewater
treatment facilities.
10. Honey (Revenues) Collected Annually. This should include all the money
you collect for operating and financing all parts of the wastewater
facil1t1es--collect1on, treatment, disposal and debt service. DO NOT
include grant monies.
11. Annual Sewer Service Charge Per Household. This should be an estimate of
the typical total annual sewer service bill for a residential customer.
One method of calculating this charge would be to use the wastewater
treatment rate established 1n your sewer use ordinance and the average
wastewater flow per household.
