It is determined and declared to be necessary and conducive
to the protection of the public health, safety, welfare and convenience
of the City to collect charges for all users who contribute wastewater
to the Authority's treatment works. The proceeds of such charges
so derived will be used for the purpose of operating, maintaining
and retiring the debt for such public wastewater treatment works.
Unless the context specifically indicates otherwise, the meanings
of terms used in this article and not defined in other sections of
this chapter shall be as follows:
DEBT SERVICE
The total principal and interest payments for a given period
on long-term debt issues.
NORMAL DOMESTIC WASTEWATER
Wastewater that has a BOD concentration of not more than
200 mg/l and a suspended solids concentration of not more than 250
mg/l.
OPERATION AND MAINTENANCE
All expenditures during the useful life of the treatment
works for materials, labor, utilities and other items which are necessary
for managing and maintaining the sewage works to achieve the capacity
and performance for which such works were designed and constructed.
The term "operation and maintenance" includes replacement, as defined
below.
REPLACEMENT
Expenditures for obtaining and installing equipment, accessories
or appurtenances which are necessary during the useful life of the
treatment works to maintain the capacity and performance for which
such works were designed and constructed.
RESIDENTIAL CONTRIBUTOR
Any contributor to the Authority's treatment works whose
lot, parcel of real estate or building is used for domestic dwelling
purposes only.
RESIDENTIAL USER UNIT CHARGE
The charge which is assessed to each residential user. Residential
user unit charges are applicable only to residential contributors.
SEWER SERVICE CHARGE
The combination of all service charges for sewer services,
including user charges and debt service charges.
USEFUL LIFE
The estimated period during which a treatment works will
be operated.
USER CHARGE
That portion of the total wastewater service charge which
is levied in a proportional and adequate manner for the cost of operation,
maintenance and replacement of the wastewater treatment works.
WATER METERS
A water volume measuring and recording device, furnished
and/or installed by either the North Hudson Sewerage Authority or
by a user and approved by the North Hudson Sewerage Authority, or
by the water purveyor for the area.
Each user shall pay his/her proportionate share of operation,
maintenance and replacement costs for the services provided by the
Authority based on his/her proportionate contribution to the total
wastewater loading from all users as determined by water meter readings
acceptable to the Authority.
A. Residential contributors. Quarterly user charges will be based on
average quarterly water usage.
B. Industrial and commercial contributors. User charges shall be based
on actual water usage during the current quarter. If a commercial
or industrial contributor has a consumptive use of water, or, in some
other manner, uses water which is not discharged into the wastewater
collection system, the user charge for that contributor may be based
on readings of a wastewater meter or separate water meter installed
and maintained at the user's expense, and in a manner acceptable
to the Authority.
C. Fixed charge.
|
Annual debt service cost + annual billing and collection cost
+ annual cost to treat infiltration/inflow = total annual fixed charges
|
(1) Residential user unit charge. The residential user unit charge is calculated as follows, using the pollutant concentrations defining "normal domestic wastewater" in §
342-35.
|
Residential unit charge unit flow charge + (unit BOD charge)
(BODND)(0.00834) + (unit SS charge) (SSND)(0.00834)
|
|
Where:
|
|
|
Residential unit charge is in $/1,000 gal.
|
|
|
Unit flow charge is in $/1,000 gal. from § 342-37D.
|
|
|
Unit BOD charge is in $/lb. BOD from § 342-37D.
|
|
|
Unit SS charge is in $/lb. SS from § 342-37D.
|
|
|
BODND is the normal domestic BOD strength
in milligrams per liter (mg/l).
|
|
|
SSND is the normal domestic SS strength
in mg/l.
|
|
|
0.00834 is a unit conversion factor from mg/l to pounds.
|
(2) Each user shall pay a user charge rate for operation, maintenance
and replacement. The fixed charge per customer per quarter shall be
$________. In addition, each contributor shall pay a user charge
rate for operation and maintenance, including replacement of $________ per 1,000 gallons of water, or wastewater, as determined
in the preceding subsection, and an additional $_____ per 1,000 gallons of water for debt retirement.
D. Surcharge. For those users whose wastewater has a strength greater
than normal domestic sewage, a surcharge in addition to the normal
user charge will be collected. The surcharge for operation and maintenance,
including replacement, is:
|
Unit Costs
|
|
Unit cost for flow in $/gallon
|
=
|
Annual $ to treat annual flow/estimated annual hydraulic loading
|
|
Unit cost for BOD in $/pound
|
=
|
Annual $ to treat annual BOD/estimated annual BOD loading
|
|
Unit cost of SS in $/pound
|
=
|
Annual $ to treat annual SS/estimated annual SS loading
|
E. Discharge of toxic pollutants. Any user which discharges any toxic
pollutants which cause an increase in the cost of managing the effluent
of the sludge from the Authority's treatment works, or any user
which discharges any substance which singly or by interaction with
other substances caused identifiable increases in the cost of operation,
maintenance or replacement of the treatment works, shall pay for such
increased costs. The charge for each such user shall be as determined
by the responsible plant operating personnel and approved by the Authority.
F. Rates applicable to whom. The user charge rates established in this
article apply to all users of the Authority's treatment works
within the City of Union City.
