[Adopted 10-11-1977]
The purpose of this regulation is to establish
fair and reasonable charges for use of the Mansfield sewerage system.
For purpose of this article, the following terms
shall have the meanings indicated:
The Water Pollution Control Authority of the Town of Mansfield.
Any structure located on property which has been assessed
for and/or is connected to the sewerage system.
All costs incidental to the complete operation and maintenance
of the treatment works, including replacement.
The meaning given to it by Section 7-245 of the General Statutes.
A.
Subject to the public hearing requirements of Section
7-255 of the Connecticut General Statutes, an annual sewer use charge
shall be imposed on each building, as defined herein:
[Amended 5-26-1998, effective 6-23-1998]
(1)
The sewer use charge for each building shall be based
on its metered water usage in accordance with the following formula:
|
Wu
| |||||
|
Cu
|
=
|
_____
|
x
|
Ct - Rt
| |
|
Wt
|
|
Where:
| ||||
|
Cu
|
=
|
The building's sewer use charge for the billing
period.
| ||
|
Wu
|
=
|
The building's metered or estimated water consumption
for the billing period.
| ||
|
Wt
|
=
|
The water consumption of all buildings connected
to the sewer system in question, as determined from meter readings
and appropriate engineering estimates.
| ||
|
Ct
|
=
|
The operation and maintenance costs for the
sewer system in question for the billing period.
| ||
|
Rt
|
=
|
The revenue collected from an industrial surcharge
and any other surcharge for discharging a disproportionate amount
of pollutant or nutrient removal.
| ||
B.
Water consumption of each building which is served
by City of Willimantic Water Department shall be as determined by
the City of Willimantic Water Department.
C.
Water consumption of each dwelling unit which is served
by a well supply shall be deemed to be equal to the average water
consumption of dwelling units which are served by the City of Willimantic
Water Department.
D.
Water consumption for each nonresidential building
served by well shall be deemed to be that estimated by the Authority.
The Authority may require the owner of any nonresidential building
served by well to submit a sworn statement of water consumption for
the year, such statement to be supported by any available records
or other evidence of water consumption. The Authority may require
the owner of any nonresidential building served by well to install
and maintain a water meter at the sole expense of such owner.
E.
In any instance in which the Authority determines that because the water consumption is greatly disproportionate from the water discharged to the sewerage system, determined in accordance with Subsections B, C and D, and would result in a building bearing more than its proportionate share of the operation and maintenance costs of the sewerage system, the Authority may make an appropriate reduction in the building's water consumption figure.
F.
In any instance in which the Authority determines
that the sewer user is producing a discharge into public sewers of
any waters or wastes having an average daily flow greater than 2%
of the average daily flow of the town, it shall be subject to review
and approval of the Authority, which may require the user to construct
and maintain, at his or her own expense, a suitable storage and flow
control facility to ensure equalization of discharge over a twenty-four-hour
period. This facility shall have a capacity of at least 80% of the
total normal volume of a twenty-four-hour production period, and the
outlet to the sewer shall be equipped with a rate discharge controller
or other approved device by the Authority.
G.
In any instance in which the Authority determines
that biological oxygen demand (BOD), suspended solids or other pollutant
concentrations from a building exceed the range of concentration of
these pollutants in normal domestic sewerage, the Commission shall
increase the building's sewer use charge by a surcharge computed in
accordance with the formula:
|
Cs = [Bc(B-300) + Sc(S-300) + Pc(P-Pn)] Vu
|
|
Where:
| ||
|
Cs = The building's surcharge for the year for
excessive concentrations.
| ||
|
B = The building's concentration of BOD.
| ||
|
Bc = Operation and maintenance cost for treatment
of a unit of BOD.
| ||
|
S = The building's concentration of suspended
solids.
| ||
|
Sc = Operation and maintenance cost for treatment
of a unit of suspended solids.
| ||
|
P = The building's concentration of any pollutant.
| ||
|
Pc = Operation and maintenance cost for treatment
of a unit of any pollutant.
| ||
|
Pn = Base level of concentration of any pollutant.
| ||
|
Vu = The building's volume of discharge for
the year.
|
H.
In any instance in which the Authority is charged
directly by an agency receiving and treating sewage collected in Mansfield
for an industrial surcharge based on the discharge on any one user
or building, said surcharge shall be added to the bill calculated
for this user or building and treated as an industrial surcharge (Rt),
as referenced above, subject to the public hearing requirements of
C.G.S. § 7-255.
[Amended 5-26-1998, effective 6-23-1998]
Sewer use charges shall be for the fiscal year
July 1 to June 30, and such charges shall be payable in advance on
January 1 of each year.
The owner of the property on which a building
is located shall be liable for and shall be billed for the payment
of sewer charges. Any such owner may request the Water Pollution Control
Authority to bill his or her legal representative or the occupant
of the building, provided that such representative or occupant authorizes
the same, in writing, but no such authorization shall affect the liability
of the owner for payment.
Sewer use charges, together with interest thereon,
shall constitute a lien upon the property on which the building is
located, and such lien may be foreclosed and such charges and interest
may be collected as provided in Section 7-258 of the General Statutes
and other applicable statutes.
All industrial users who utilize sewerage works
constructed under EPA project C090179 01 shall be obligated to make
industrial cost recovery payments to the Town of Mansfield in accordance
with applicable federal regulations. The Town of Mansfield shall solicit
the EPA's review and approval of its proposed cost recovery system
prior to or concurrent with the connection of said industry.
