(a) Charges to pay maintenance and operating costs.
The
user charges established by the city shall be adequate to pay the
maintenance and operating costs of the system.
(b) Users to pay monthly minimum plus proportionate share.
Each user shall pay a monthly minimum plus a proportionate share
of the cost of the operation and maintenance of the system, including
replacement. The user charge shall distribute the cost of operation
and maintenance of the system with respect to operation and maintenance
costs.
(c) Definition of symbols in formula.
The following symbols
and definitions shall be used in the formula for calculating the monthly
sewer use charges:
Cu
|
Sewer user charge per month
|
Ct
|
Operation and maintenance cost per month
|
Vt
|
Volume of sewage to the plant per month
|
Vu
|
90% of the monthly average water used by each user, as measured
by the water meter, during the months of December, January and February
|
K
|
Monthly minimum - $3.45 per month
|
(d) Calculation of monthly charges.
It is hereby determined
that the treatment works is primarily flow dependent and that the
BOD, suspended solids, and other pollutant concentrations discharged
by all users are approximately equal; therefore the monthly rates
and charges to all users shall be determined as follows:
(e) Annual review.
The city council shall review user charges
annually and revise them periodically to reflect actual treatment
works operation and maintenance costs.
(f) Sample calculations.
Sample calculations of monthly
sewer user charge:
(1) Annual O&M as estimated on page 6 of facility plan: $34,584.00.
(2) Annual volume of sewage to plant (1974-1975 figures): 86,010,214
gallons.
(3) Sewer user charge formula: Cu = K + (Vu) [Cu = K + Ct/Vt (Vu)]

$2,882 1,000 = $0.40/1000 gallons
