-------
Getting Started
You’re a federal or state official evaluating the financial
soundness of a wastewater utility operation. Obviously, you
need a general understanding of wastewater operations. But
pnmarily, you need to know if the utility is generating enough
revenue to properly operate and maintain itself.
Why?
Because how a wastewater utility handles revenues and
expenses is crucial. Good financial management can prevent
premature deterioration of facilities that ultimately leads to
discharge permit violations.
This manual will help you evaluate whether wastewater
utility’s user service charges are adequate tocover operations.
It will tell you how to organize for a field visit, what homework
to do, with whom to meet, what questions to ask, what
records to review and how to analyze all the information you
gather.
Your first evaluations will be time-consuming. However,
with some experience. you’Ll learn exactly what documents to
get and what questions to ask—and how to ask them!
Eventually, you can evaluate a utility’s financial operation in
a few hours.

-------
You don’t need to be an accountant or have a background
in utility finance. You can use this guide to effectively
evaluate the system’s financiaihealth.
Wastewater user fees are NOT a mystery.
Once you understand all thepieces and fit them together,
they’ll create a clear picture of the overall financial operation.
The Big Picture
You will look at the wastewater treatment facility’s
financial management system and how it fits into the overall
utility operation.
Two major components—revenues and expenses—make up
the financial operation. And these two components have
several pieces. We’ll examine the relationship between these
pieces closely.
Be aware that the financial operation doesn’t stand alone.
To properly evaluate a facility, consider other things that can
impact the health of the system. For sound operation, a
facility should have:
• an effective organizational structure,’
• clear, written policies and procedures,
• trained, conscientious staff,
• efficient operation and maintenance practices,
• accurate budgets, audits and record-keeping,
• good customer relations.

statements.
A user service charge is the central and most important
piece of a facility s financial puzzle. Its the fee charged users

-------
Special User Charge Requirements
ForEPAfunded facilities, the utilitymust comply
with its EPA approved user charge system to:
Charge each user (or user class) its proportionate
share of the operation, maintenance and
equipment replacement costs based on qupntity
and qw lity of discharged wastes. —
• Notify users of rates rnnii 11y . —
I • Distribute infiltration and Inflow costs
proportionally among all users.
• Impose surcharges for wastewater that requires
additional treatment.
• Establish a financial management system to
account for revenues and expenses.
(For further EPA requirements, see page 23.)
State and local governments may:
• Specify an acceptable accounting system—how a
utifity records, classifies and reports information
on finances and operation of the system.
• Require certain reserve funds or coverage ratios
on debt.
for the collection and treatment of wastewater. It accounts for
nearly all of a system’s total revenue.
An effective rate structure will cl arge users their
proportionate share of the operatton. maintenance, equipment
replacement and debt service costs. Usually, a local
government implements its rate structure through an
ordinance or resolution.
Keep these things in mind:
• The user service charge for wastewater collection and
treatment should relate proportionally to the quantity and
quality of wastewater produced by the user. If the discharge
from all users is substantially equal—as expected from resi-
dential customers—then user fees would be based on the vol-
ume of wastewater. For commercial and industrial users who

-------
discharge high strength wastes, a surcharge is added because
it costs more to treat their wastes.
Normally the user service charge is based on the cus-
tomer’s water meter reading. Frequently, meter readings are
adjusted to account for water not discharged to the sanitary
sewer system. If water meters do not exist, then the charge is
based on equivalent dwelling units.
• How are the fees structured? Are the fees proportional
to use? Volume discounts or premiums are not proportional.
Is there a minimum bill? If so, is the minimum bill compatible
with the concept of proportional user service charges? Does
the utility bill monthly?
• The user service charge should include the costs of
transporting and treating inflow/infiltration. When the I/I
costs cannot be assigned to any particular user or user cate-
gory, the costs are distributed proportionally among all users.
• Are the fees reviewed and adjusted annually?
• Is there provision for informing customers annually of
the user fee schedule?
• Are customers outside the political boundary bified in
proportion to their use?
There are other pieces to the revenue picture but they are
very minor.
• Hookup/Impact fees... charges for new customers con-
necting to existing sewer lines.
• Taxes/Assessments.. .special front footage or other
annual charges.
• Interest earnings.. .interest earned from investments
like checking accounts, savings accounts and treasury bills.
• Other... may include sales of treatment byproducts such
as composted sludge and the penailties charged for not pay-
ing the sewer bill on time. This penalty is often a percentage
of the total bill.

-------
The Pieces...
What Do They Mean?
So far, we examined the pieces comprising the cash flow
operations of a wastewater utility. Obviously, revenues must
equal or exceed expenses for the operation to be financially
healthy. If that is not the case, the utility is in trouble.
Ultimately, facilities will deteriorate and violate discharge
standards.
Keep in mind your examination is a “snap shot” view of
where the utility’s financial operations are at this particular
time. Be aware of any blips in the snap shot. Is there
anything unusual happening with the financial operations
this year? For instance, were expenses down this year
because of al-i unfilled vacancy? Were revenues off because of
inadequate billing or collection procedures?
S
Where Do You Find Them?
Now you know how to recognize the user service charge
system components. You know what each piece means. But
where do you find them?
The pieces for the user service charge system puzzle are in
the local government’s financial records, the heads of local
government managers and at the treatment facility. This
means that YOU will venture into the land of local
government to solve the puzzle. You must know what
information to ask for, who to talk with, how to recognize
what you see and how to interpret what you find.

Dear Mr. Sullivan:
This letter confirms our appointrtlent for (time), (month)
(date). (year), and lets you know what information I will need
to obtain during our meeting.
As we discussed on the telephone today. I will be evaluating
Smithtowns wastewater user service charge system. I need to
determine if it is generating sufficient revenues to cover
operation. maintenance, equipment replacement and debt
service costs. The evaluation will consist of (1) a meeting with
you and your staff to discuss the utilitys financial operations
and (2) a brief tour of the wastewater facilities. These
activities should take about four hours to complete.

the meeting. Please complete as much of this worksheet as
you can before our meeting and be prepared to respond to the
questions. I will also need to review the following information
on your wastewater operation:
• the most recent audited financial statement,
• the current budget,
• current year-to-date revenues,
• current year-to-date expenses.
• the wastewater rate schedule and ordinance (or
resolution), and
• the sewer use and pretreatment ordinances.

Follow-up letter after a user charge eualuottort
(Date)
Mr. James Sullivan
Finance Director
City of Smithtown
100 S. Main St.
Smithtown, TN 37923
Dear Mr. Sullivan:
It was a pleasure to meet with you and your staff on (date) to
discuss your wastewater utility’s financial operations. As a
result of our discussions and the tour of your wastewater
treatment facility. I noted the following concerns.
1. The was tewater and water accounting systems are not
separate. The water and wastewater operations need to be
financially independent arid self-sufficient. The
Smithtown wastewater treatment facility was partially
financed by a grant from the U.S. Environmental
Protection Agency. This means Smithtown must establish
a financial management system which separately
accounts for wastewater revenues and expenditures. The
system must also identify the basis for determining
operation, maintenance, equipment replacement. debt
service costs and user service charges.
2. The wastewater utility does not collect surcharges from
users discharging high-strength waste although the
Smithtown wastewater system’s sewer use ordinance
requires a surcharge on thos users whose wastes
increase operation arid maintenance costs. This
ordinance must be enforced as a condition of your EPA
grant.
3. The actual wastewater expenses to date at the half-way
point in this fiscal year are $125.000. The total budgeted
amount for the fiscal year is $200,000. This results in a
projected deficit of 50 .0O0 for the year. User service
charges must be increased to provide the needed
operating revenue since collection of surcharge revenues
will not be sufficient to eliminate the deficit.

-------
4. The wastewater unit volume rate is insufficient to cover
the operational costs of the utility. A rough calculation
showed that the OM&R costs are$1.20/ 1000 gallons and
____ debt service costs are $0.60 for a total rate of $1.80! 1000
gallons.
___ 5. The accounting system does not budget for an equipment
____ replacement fund. You need an equipment replacement
fund to pay for equipment and accessories that wear out
___ during the life of the treatment facility. The fund is not to
be used for expanding the capacity or enhancing the
treatment facility ’s performance. It must be used to keep
____ the facility operating at the level for which it was designed
___ and constructed. Again, this is a requirement of the EPA.
___ 6. At the treatment facility, the secondary clarifier sludge
____ return pump was inoperable and a backup pump was not
available. The sludge return pump is essential to proper
___ operation. As we discussed during the visit, you should
install a temporary pump as soon as possible and repair
___ or replace the inoperable sludge pump. You need a
backup pump to prevent this circumstance from
reoccumng.
____ 7. The treatment plant grounds were poorly maintained. The
___ grass needed mowing: discarded equipment was lying
___ around: spillage from the sludge hauling operation
created a nuisance. The appearance of a wastewater
treatment facility is usually a good indicator of the level of
___ professionalism, motivation and training of the staff. It
___ also may be an indicator of inadequate funding/staffing of
____ the treatment facility. As a result of our discussions and
____ tour of the facilities, it appears that ad itional staff is
___ needed to achieve proper operation and maintenance.
___ 8. At the treatment facility, there was only a two-day supply
of chlorine and a limited supply of laboratory reagents
and chemicals on hand. Good management practice
requires an adequate supply of essential chemicals and
reagents on hand to operate and maintain the facility
properly. From our discussion, it appears the Smithtown
___ utility should revise its purchasing procedure to allow the
— superintendent to order routine supplies directly without
— waiting for governing body approval.

-------
9. This system had exceeded its monthly average BOD
NPDES permit limit fOr two consecutive months. The
major cause of this violation appears to be inadequate
sludge return. The pump outage discussed above should
be rectified immediately.
Many of the above concerns are consistent with the
conclusion that Smithtown’s wastewater treatment facility
needs more financial resources for proper operation and
maintenance. I have enclosed a copy of EPA’s public iion
Building Support for Increasing User Fees that tells how to
increase the facility’s revenue base.
Please develop a corrective action plan with compliance dates
to address the above findings, and submit the plan to this
office no later than (date).
Our office will be glad to work with the City of Smithtown to
protect its water quality and improve its wastewater financial
operations. If you have questions about this report, please feel
free to call me at (area code and number).
Sincerely,
Anne Taylor.
