[Ord. No. 594, § 1, 5-11-1982]
The purpose of this article shall be to generate sufficient
revenue to pay all costs for the operation and maintenance of the
complete wastewater system. The costs shall be distributed to all
users of the wastewater system in proportion to each user's contribution
to the total loading of the treatment works. Factors such as strength
(BOD and SS), volume and delivery flow rate characteristics shall
be considered and included as the basis for the user's contribution
to ensure a proportional distribution of operation and maintenance
costs to each user (or user class).
[Ord. No. 594, § 2, 5-11-1982]
The city or its city engineer shall determine the total annual
costs of operation and maintenance of the wastewater system which
are necessary to maintain the capacity and performance, during the
service life of the treatment works, for which such works were designed
and constructed. The total annual cost of operation and maintenance
shall include but need not be limited to, labor, repairs, equipment
replacement, maintenance, necessary modifications, power, sampling,
laboratory tests and a reasonable contingency fund.
[Ord. No. 594, § 3, 5-11-1982]
The city or its city engineer shall determine each user's
average daily volume of wastewater which has been discharged to the
wastewater system, which shall then be divided by the average daily
volume of all wastewater discharged to the wastewater system, to determine
each user's volume contribution percentage. The amount used as
the total average daily volume of wastewater shall exclude infiltration
and inflow. The city or its city engineer shall determine each user's
average daily poundage of five-day 20° C. bio-chemical oxygen
demand (DOB) which has been discharged by the average daily poundage
of all five-day BOD discharged to the wastewater system to determine
each user's BOD contribution percentage.
The city or its city engineer shall determine each user's
average suspended solids (SS) poundage which has been discharged to
the wastewater system which shall then be divided by the average daily
poundage of all suspended solids discharged to the wastewater system,
to determine the user's suspended solids contribution percentage.
Each user volume contribution percentage, BOD contribution percentage
and suspended solids contribution percentage shall be multiplied by
the annual operation and maintenance costs for wastewater treatment
of the total volume flow, of the total five-day 20° C. BOD and
of the suspended solids, respectively.
[Ord. No. 594, § 4, 5-11-1982]
The City or its city engineer will determine the average suspended
solids (SS) and biochemical oxygen demand (BOD) daily loadings for
the average residential user. The city or its city engineer will assess
a surcharge rate for all nonresidential users discharging wastes with
BOD and SS strengths greater than the average residential user. Such
users will be assessed a surcharge sufficient to cover the costs of
treating such users' above-normal strength wastes. Normal strength
wastes are considered to be 200 p.p.m. BOD and 250 p.p.m. SS. The
surcharge rate structure for such above-normal strength waste dischargers
is attached. (Appendix A, adopted herein by reference.)
[Ord. No. 594, § 5, 5-11-1982]
Each nonresidential user's wastewater treatment cost contribution as determined in sections 17-100 and 17-101 shall be added together to determine such user's annual wastewater service charge. Residential users may be considered to be one class of user and an equitable service charge may be determined for each user based upon an estimate of the total wastewater contribution of this class of user. The governing body may classify industrial, commercial and other nonresidential establishments as a residential user, provided that the wastes from these establishments are equivalent to the wastes from the average residential user with respect to volume, suspended solids and BOD. Each user's wastewater treatment cost contribution will be assessed in accordance with the attached rate schedule. (Appendix B, adopted herein by reference.)
[Ord. No. 594, § 6, 5-11-1982]
The city shall submit an annual statement to the user for the
user's annual wastewater service charge or 1/12 of the user's
annual wastewater service charge may be included with the monthly
water and/or wastewater utility billing. The city shall add a penalty
of 1 1/2% per month if the payment is not received by the city
within 15 days. Should any user fail to pay the user wastewater service
charge and penalty within three months of the due date, the city may
stop the wastewater service to the property.
[Ord. No. 594, § 7, 5-11-1982]
The city shall review the total annual cost of operation and
maintenance, as well as each user's wastewater contribution percentage
not less often than every two years and will revise the system as
necessary to assure equity of the service charge system established
herein and to assure that sufficient funds are obtained to adequately
operate and maintain the wastewater treatment works. If a significant
user, such as an industry, has completed in-plant modifications which
would change that user's wastewater contribution percentage,
the user can present at a regularly scheduled meeting of the governing
body, such factual information and the city shall then determine if
the user's wastewater contribution percentage is to be changed.
The city shall notify the user of its findings as soon as possible.
[Ord. No. 594, § 8, 5-11-1982]
Each user will be notified, at least annually, in conjunction
with a regular bill, of the rate and that portion of the user charges
which are attributable to wastewater treatment services.
[Ord. No. 594, § 9, 5-11-1982]
The discharge of any waters containing toxic or poisonous solids, liquids or gases in sufficient quantity, either singly or by interaction with other wastes, to contaminate the sludge of any municipal system or to injure or interfere with any sewage treatment process, constitute a hazard to humans or animals, create a public nuisance, or create any hazard in or have an adverse effect on the waters receiving any discharge from the treatment is hereby prohibited. Article V of this chapter contains additional requirements covering the use of the city's public sewers.
[Ord. No. 594, § 10, 5-11-1982]
No person shall make connection of roof downspouts, exterior
foundation drains, areaway drains or other sources of surface runoff
or groundwater to a building sewer or building drain which in turn
is connected directly or indirectly to a public sanitary sewer.
[Ord. No. 594, § 11, 5-11-1982]
The size, slope, alignment, materials of construction of all
sanitary sewers and sewer connections, and the methods to be used
in excavating, placing of the pipe, jointing, testing and backfilling
the trench, shall all conform to the requirements of the building
and plumbing code or other applicable rules and regulations to the
city and the state. In the absence of code provisions or in amplification
thereof, the materials and procedures set forth in appropriate specifications
of the A.S.T.M. and W.P.C.F. Manual of Practice No. 9 shall apply.
