There is hereby established in the Village of Oakfield a system
of sewer charges which shall be used for payment of the cost of management,
maintenance, operation, repair of and amortization of the capital
construction costs of the wastewater treatment system.
Unless otherwise stated herein, all charges shall be determined
at least annually by the Village Board of Trustees by a resolution
duly adopted by a majority of its membership.
The sewer charge shall be comprised of two components:
A. Operation and maintenance charge. An operation and maintenance charge
shall be levied on all users of the wastewater treatment system. The
operation and maintenance charge will result in the distribution of
the cost of operation and maintenance, including equipment replacement
of the wastewater treatment system, to each user in proportion to
such user's contribution to the total wastewater loading of the treatment
works as required by the Federal Water Pollution Control Act. Each user's contribution shall be based on sewer use,
in gallons, unless the discharge contains concentrations exceeding
250 mg/l of BOD and/or 300 mg/l of suspended solids, in which case
a surcharge shall be levied to cover the additional operation and
maintenance costs necessary to transport and treat these wastes. As
a minimum for the first year of operation, operation and maintenance
charges shall be computed based on the most recent average yearly
water consumption data. Thereafter, the quarterly charges shall be
based on the most recent annual water use.
(1) The rate of the operation and maintenance charge shall be as set
from time to time by resolution of the Board of Trustees for each
1,000 gallons or fraction thereof of water consumed or estimated to
be used. Additionally, there shall be a basic charge of per unit per
quarter for each user and a debt service charge of per unit per quarter
for each user, each to be as set from time to time by resolution of
the Board of Trustees.
[Amended 3-10-1980 by L.L. No. 2-1980; 5-24-1982 by L.L. No. 2-1982; 6-13-1988 by L.L. No. 6-1988; 6-24-1991 by L.L. No. 3-1991; 6-23-1997 by L.L. No. 1-1997; 12-11-2006 by L.L. No. 3-2006; 7-14-2008 by L.L. No. 1-2008; at time of adoption
of Code (see Ch. 1, General Provisions, Art. I)]
B. An operation and maintenance surcharge shall be levied on all users discharging excessive compatible pollutants as defined in Subsection
A above. This charge shall represent the proportionate share of the Village operation and maintenance costs based on wastewater flow and mass emission rate as required by the Federal Water Pollution Control Act. The surcharge shall become due and payable quarterly.
(1) The formula for the sewer surcharge shall be computed by the Department.
The amount of the surcharge shall be the product of the surcharge
factor and the established treatment charged. The general form for
the determination shall be as follows:
SF = a (BOD - 250) + b (SS - 300)
|
250
|
300
|
Where:
|
SF
|
=
|
Surcharge factor
|
BOD
|
=
|
Milligram per liter of biochemical oxygen demand, as defined in § 208-1
|
SS
|
=
|
Milligrams per liter of suspended solids, as defined in § 208-1
|
a
|
=
|
Decimal portion of the total operation and maintenance cost
to treat one pound of BOD, to be determined annually by the Department
|
b
|
=
|
Decimal portion of the total operation and maintenance cost
to treat one pound of SS, to be determined annually by the Department
|
(2) If any of the values for BOD and SS, as determined by laboratory
analysis, are less than 250 mg/l and 300 mg/l respectively, the factor
for that pollutant shall be eliminated from the formula.
Example:
|
|
A commercial establishment discharges wastes into the public
sewer system at the rate of 100,000 gallons per year.
|
|
The discharged wastes have been found to include the following
concentrations of pollutants:
|
|
BOD = 450 mg/l
|
|
SS = 200 mg/l
|
|
Values for a and b are 0.2 and 0.3 respectively.
|
|
Normal sewer charge = 100,000 gallons x 156
1,000 gallons
|
|
= $156 per year
|
|
SF = 0.2 (450 - 250) = 0.16
250
|
|
NOTE:
|
Factor for SS has been dropped because values are below normal
limits.
|
|
Surcharge = 0.16 x $156 = $24.96
|
|
Total sewer charge = $156 + $24.96 = $180.96/year
|
Except as herein provided in this chapter, the sewer use shall
be the total metered water use.
In the event the owner of a lot, parcel of land, building or
other premises discharging wastewater into a sanitary sewer, either
directly or indirectly, uses metered Village water in excess of 15,000
gallons per quarter year and claims a significant portion of the metered
water does not return to the sanitary sewer, such owner shall file
a written statement to that effect with the Department. Upon receipt
of such statement, the Department may authorize the installation,
at the owner's expense, of a separate meter or meters to measure the
metered water returning to the sanitary sewer. If the installation
of such a meter or meters is not practical, the Department shall determine
a method of measuring the wastewater entering the sanitary sewer.
In such cases, the sewer charges may be based on this determination.
In the event that the owner of a lot, parcel of land, building
or other premises discharging wastewater to the sanitary sewer, either
directly or indirectly, uses metered Village water and water other
than metered Village water, or uses water other than metered Village
water exclusively, the Department shall determine a method of measuring
or estimating the wastewater discharge entering the sanitary sewer.
In such cases, the sewer surcharge shall be based on this determination.
All expenses in connection with metering shall be charged to
the owner of the land.
