it were normal sewage

sewage

sewage

|
Note: If any difference of terms in the equation above is negative,
then that portion of the equation shall not be used; that is, the
difference shall be set to zero when it is negative.
|
Note: All averages are arithmetic averages determined from available
data during the billing period.
|
The service area of the POTW shall be considered as a whole
in determining the user charge so that the cost of service is distributed
to all users.
The volume of flow to be used in computing sewer service charges
and abnormal sewage surcharges shall be based upon metered water consumption
as shown on the records of meter readings maintained by the Town Water
Department. In the event that a person discharging wastes into the
POTW produces evidence to the Authority demonstrating that a substantial
portion of the total amount of metered water does not reach the POTW,
then the Authority shall either establish a percentage of the total
metered water to be used as a basis for such computations, or direct
the installation of appropriate flow-measuring (and totalizing) devices
to measure and record the actual amount of flow into the POTW. In
the event that a person discharging wastes into the POTW procures
all or part of his water supply from unmetered sources, the Authority
shall either direct the installation of water meters on the other
sources of water supply or direct the installation of appropriate
flow-measuring devices to measure and record the actual amount of
flow into the POTW. Any water meters and/or flow-measuring devices
installed pursuant to this section shall be of a type and design acceptable
to the Authority and shall be installed, maintained, and periodically
tested as required by the Authority, at the owner's expense. All such
meters and/or flow-measuring devices shall be subject to periodic
inspection, testing, and reading by the Authority. Any person discharging
wastes into the POTW may install a flow-measuring device at his option,
of the type, design, installation, and maintenance standards of the
Authority, at the owner's expense.
The billing period shall be quarterly.
The additional charges and fees associated with the operation
of the pretreatment program shall be assessed the user and include:
A. Reimbursement of costs of setting up and operating the pretreatment
program.
C. Monitoring, inspection, and surveillance procedures.
D. Costs of equipment and supplies.
E. Reviewing accidental discharge procedures.
F. Construction inspections.
H. Application for consistent removal status as outlined in 40 CFR 403.
I. Other reasonable expenses to carry out the program to satisfy the
requirements of this chapter, the NYSDEC and the federal government.
The charge for treatment and disposal of trucked or hauled waste
which has been introduced into the POTW shall be as established by
the Town Board. The manner of determining the volume dumped shall
be at the discretion of the Authority.
The Town may institute an equitable procedure for recovering
the costs of any capital improvements of those parts of the POTW which
collect, pump, treat, and dispose of industrial wastewaters from those
persons discharging such wastewaters into the POTW.
Sewer service charges shall be payable and collected in the same manner and at the same time as bills for the consumption and use of water. Late payment and unpaid charges, including penalties, shall be collected as set forth in Article
XI.
The POTW shall be operated on the basis of a fiscal year commencing
on the first day of June and ending on the 31st day of May.
The Town Board shall have the authority to impose impact fees
on new development, which development may:
A. Cause enlargement of the service area of the POTW.
B. Cause increased hydraulic and/or treatment demands on the POTW.
Revenues derived from user charges and associated penalties,
and impact fees, shall be credited to a special fund known as the
"sewer fund." Monies in this fund shall be used exclusively for the
following functions:
A. For the payment of the management, maintenance, operation, including
repair and replacement, costs of the Town POTW;
B. For the discovery and correction of inflow and infiltration;
C. For the payment of interest on and the amortization of or payment
of indebtedness which has been or shall be incurred for the construction
or extension of the Town POTW; and
D. For the extension, enlargement, replacement of, and/or additions
to the Town POTW, including any necessary appurtenances.
