chargeable to volume $/1,000 gallons.
|
Vu = Volume of wastewater from industrial
users $/unit of time.
|
Bc = Unit cost of treatment chargeable
to BOD $/lb.
|
Bu = Amount of BOD from industrial user,
lbs./unit of time.
|
Sc = Unit costs of treatment chargeable
to SS $/lb.
|
Su = Amount of SS from industrial user
lbs./unit of time.
|
(b) The unit
costs applicable to volume, BOD and SS shall be the total of the unit
costs from capital investment and from operation and maintenance.
The total capital investment costs will be allocated as a percentage
to BOD, volume and SS so that the total equals 100% and similar the
operation and maintenance costs will be allocated on a percentage
basis to volume, COD and SS. The allocations for capital costs may
be different than operation and maintenance costs allocations and
shall be applied so as to represent the total costs associated with
each parameter.

(c) The city
shall review at least semiannually the basis for determining charges
and shall adjust the unit treatment cost in the formula to reflect
increases or decreases in wastewater treatment costs based on the
previous year's experience.
(d) The city
shall bill the discharger by the month and shall show industrial waste
charges as a separate item on the regular bill for water and sewer
charges. The discharger shall pay monthly in accordance with practices
existing for payment of sewer charges.
(1995 Code of Ordinances, Title V, Chapter 51, Section
51.18)
Volume increases or changes in the characteristics of the waste
flow or increased standards set by regulatory authorities may require
that wastewater collection, treatment or other disposal facilities
of the city be improved, expanded or enlarged in order to treat the
waste. The capital investments made by the city will be calculated
into the industrial user charges so that the industrial will pay its
fair and equitable share of the total costs of the treatment system.
If a federal government grant is obtained for waste system improvements,
then significant industrial users (as defined by government grant
regulations) shall pay a cost recovery charge (in addition to the
city's industrial user charge) on that portion of the federal grant
applicable to the treatment of the industrial user's waste. The cost
recovery charge shall be calculated and applied in accordance with
the requirements of the federal government grant.
