Oregon User  Charge  Study

-------
Introduction
PurDose of the Survey
Part of the State’s ongoing responsibility is to
acquire financial and technical information about
its communities. The information acquired from
this user charge survey allows the State to
monitor the ability of its communities to achieve
financial self-sufficiency for wastewater treat-
ment operations. There is an especially strong
need for the State to look even more closely at
user charges since local municipalities will be
financing their future wastewater construction
without the assistance of federal grants. The
future success of wastewater pollution control in
the State will depend on the ability of local
communities to maintain financially self-suffi-
cient wastewater treatment operations.
Do communities have healthy t ser charge
systems that provide adequate revenues to
support operations and debt repayment? To
answer this question and plan for the future,
State and local officials must know where
communities stand in running self-sufficient
wastewater systems.
To obtain information on the financial solvency
of its communities, the State of Oregon under-
took a survey of user charges following the
procedures given in the United States Envuon-
mental Protection Agency’s publication Looking
at User Charges: A State Survey and Report
(EPA 430i09-87-0008). The survey’s 11 ques-
tions, although deceptively simple, generate a
wealth of information on residential unit costs.
A copy of the survey form is provided in Appen-
dix A. This survey was conducted during May
of 1990.
Responses on demographic and utility character-
istics were used to calculate unit costs and flows,
examine economic impact and ensure valid
comparisons between communities. Costs data
provided the basis for comparing user charge
systems and the costs of operation, maintenance,
replacement and capitalization. Revenue ques-
lions allow 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
Organization of ReDort
This report is divided into eight sections to
evaluate the financial self-sufficiency of munici-
pal wastewater treatment operations.

VIII Summary Findings
A summary table of each community’s responses
to the survey is presented in Appendix B
I. Covering the 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 analysis
shows the ratio of revenues to costs. For com-
munities where revenues are not adequate to
cover costs, i.e., the ratio is below 100%, the
communities should reassess their user charge
systems and other sources of revenues to ensure
proper funding.
In this analysis. 42% of the communities showed
revenues below their costs. These communities
had an average overall revenue shortfall of 25%

systems only.)
II. Unit Costs by Treatment Level
Analysis of unit costs (cost of treatment per 1000
gallons) helps identify communities where costs
are usually high or low. Unit costs for individual
communities vary dramatically and the analysis
reflects this fact.
Communities with secondary treatment averaged
$2.24 per 1000 gallons, and advanced treatment
systems averaged $1.88 per 1000 gallons. The
unit wastewater treatment costs averaged $2.22
per 1000 gallons. Operation, maintenance, and
equipment replacement costs averaged $1.66 per
1000 gallons.

Ill. Average Annual Total Residential Costs
and Sewer Service Charges per Household
The average annual total residential treatment
costs and sewer service charges per household
serves as a basis for later analyses such as (1) the
percentage it represents of median household
income, and (2) whether user charges are cover-
ing actual costs. Here, the data has been arrayed
to show the distribution by treatment levels.
The seconciary treatment residential costs were
concentrated in the $50 to $150 range, while
advanced treatment costs were in the $101 to
$150 range. User charges for both treatment
levels fell in the same ranges as did residential
costs. The average residential treatment cost
was $146 per household per year while the
average residential user fee was $127 per house-
hold per year.

Are residential customers paying their fair share
of the costs? Or is one class of users subsidizing
another? Analysis of data on the portion f the
flow, costs, and revenues attributable to residen-
tial users allows answers to these questions.
Based on the analysis, communities may restruc-
ture their user charge systems to d.istribute costs
more equitably.
This analysis shows that in many communities
residential users (48%) may be paying less than
their share of treatment costs. For communities
utilizing secondary treatment, about 47% of
communities charge residential customers less
than their estimated share of treatment costs; for
advanced treatment, this figure is 60%.

V. Ability of Residential Sector to Cover
Residential Costs
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.
Data can also be used to predict the ability of the
community to generate more revenue by increas-
ing its sewer service charges.
In this analysis, communities had an average
total residential treatment cost which was 0.8%
of the MN.!, but their average sewer service
charge was 0.7% of the MHI.

V!. Planning For Equipment Replacement
Examination of how communities are planning
for future equipment replacement identifies those
communities that may need to reassess their user
charge systems. Communities may be shorten-
ing the life expectancy of their facilities and
possibly be causing future compliance problems
by not pmvidL g adequate funds for equipment
replacement.
This analysis shows that communities with
replacement funds set aside 11% of their operat-
ing costs for equipment replacement.

VII. Debt Burden Without Grant Contribu-
The effect of grant funding on capital costs was
examined by making adjustments to the debt
financing cost figure (as reported in the surveys)
to reflect “total” costs of capital without Federal
or State grant assistance. This roughly deter-
mined the impact of grant assistance on commu-
nity ueatment costs.
This analysis showed that the average debt
financing costs for advanced ueatment would
have increased from $.49 to $2.74 per 1000
gallons, while it would have increased from $.60
to $2.58 for secondary treatment. In this analy-
sis, grants reduced the average total treatment
costs from $4.25 per 1000 gallons to $2.22 or
48%.

INSTRUCTIONS FOR COMPLETING SURVEY
These Instructions include information plus directions to help you complete
some of the questions. If something does not fityour situation, answer as
best as you can and explain the problem or call the number shown in the cover
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
available. —
1. Households. This should be the total number of households (residential
customers) serviced, not the number of people or population. (Residential
apartment buildings should 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 in gallons per day. If your flow is
calculated in 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 daily flow per household
residential flow T customers (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 infiltration/inflow.
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, arid disposal (outfalls, sludge disposal).
7. Annual Costs. This number should include annual “operating costs,”
“maintenance costs,” “replaceiient costs” for wastewater collection and
treatment, and any charges from Regional systems. (ItDOESNOT include
the costs of stewater loans and bonds, or depr?clation).
A4

-------
Ooerating costs include labor, materials and supplies, utilities, and
overhead (such as office rent).
Maintenance costs include preventive and corrective maintenance.
Reolacernent costs include costs to maintain but not to extend the useful
life of the facilities (like pumos and motors).
8. Equipment Replacement. This question is intended to determine wh?t
percentage of the operating costs you included in Question 7 are being .ut
aside to maintain but not extend the useful life of the facilities (like
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. Money (Revenues) Collected Annually. This should Include all the money
you collect for operating and financing all parts of the wastewater
facilities--collection, 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 in your sewer use ordinance and the average
wastewater flow per household.
