[Adopted 7-7-1986]
Under authority of Titles III, VI and VII of
the City Charter of the City of Watertown, the following rules and
regulations are hereby promulgated by the City of Watertown pertaining
to the discharge of stormwater, well water, groundwater, cooling water,
unpolluted water, industrial wastewater, sewage or other wastewater
in the City sewer system.
These rules and regulations set uniform requirements
enabling the discharges into the wastewater collection and/or treatment
system of the City of Watertown by users whose discharges do not originate
within the corporate limits of the City. Additionally, these rules
and regulations provide the means for the establishment of an outside
user fee and collection system fee.
It is intended that all requirements contained
within adopted municipal codes, local laws and ordinances, as currently
amended, as well as future amendments to the same, governing the definition
of terms, uses, prohibited uses and discharge limitations to the City
of Watertown's wastewater collection and/or treatment system shall
remain in effect and apply here. Specific reference is made to Parts
1, 2 and 3 of this chapter.
As used in this Part 4, the following terms
shall have the meanings indicated:
The Development Authority of the North Country.
The product of a sewer's diameter (in inches) times its length
(in miles).
Any person, group of persons, corporations, governmental
bodies, etc., who contract with the City as a unit and contribute,
cause or permit the contribution of wastewater into the City of Watertown's
collection and/or treatment system where the origin of the wastewater
is outside the corporation boundaries of the City.
All users (not limited to solely industrial facilities), but excluding the Authority, meeting one or more of the criteria specified by definition contained in Part 3 of this chapter.
A.
All costs incurred by the City at its pollution control
plant as a result of accepting wastewater from outside users shall
be recovered via an outside user fee.
B.
The total cost to be recovered by the outside user
fee shall be comprised of the following elements:
(1)
All costs, including but not limited to administration,
legal, interest on temporary financing, construction, engineering
and inspection, related to the expansion of the pollution control
plant from an eight-million-gallon average daily flow to a thirteen-and-four-tenths-million
gallon average daily flow facility.
(2)
A share of the debt service on those pollution control
plant process equipment and facilities existing prior to the expansion
of the plant from an eight-million-gallon average daily flow to a
thirteen-and-four-tenths-million-gallon average daily flow facility
and which will be used for the treatment of sewage originating from
both out side users as well as users inside the corporation boundaries
of the City of Watertown. The share shall be equal to the ratio of
the average daily flow of all outside users divided by the average
daily flow of all users.
(3)
A share of the total pollution control plant operation
and maintenance costs as defined by the G8130 account of the City's
Sewer Fund. The share shall be equal to the ratio of the average daily
flow of all outside users divided by the average daily flow of all
users.
C.
An individual outside user fee shall be the individual
outside user's share of the total cost to be recovered by the outside
user fees. The individual outside user's fee shall be computed in
accordance with the formula which follows:

B.
The total cost to be recovered by the collection system

(1)
A share of the debt service on all components of the
wastewater collection system. The share shall be computed in accordance
with the formula which follows.
(2)

C.
Those users discharging directly to the City's wastewater
treatment facilities and, thereby, not utilizing any portion of the
City's wastewater collection system shall be exempt from the collection
system fee.
Under no circumstances shall the total fee (outside
user fee plus the collection system fee) assessed an outside user
be permitted to be less than 120% of the total sewer service charge
assessed a user within the corporation boundary of the City of Watertown
for an equal volume of wastewater collected and treated.
The City Manager of the City of Watertown is
authorized to enter the City into contractual agreements with designated
outside users, subject to City Council approval.
Outside users shall be required to install a
monitoring facility at the point their discharge first enters the
City's wastewater collection or treatment system. Monitoring facilities
shall be constructed, operated and maintained at the user's expense.
The purpose of the facility is to enable inspection, sampling and
flow measurement of wastewaters produced by the user. Continuous flow
monitoring and recording is required and shall be installed, operated
and maintained at the user's expense. There shall be accommodations
to allow safe and immediate access for authorized City personnel.
There shall be ample room in or near such facility to allow accurate
sampling and compositing of samples for analysis.
Designation of an outside user and significant industrial user shall require that individual outside users comply with the City's rules and regulations relating to the industrial use of the public sewer system (Part 3 of this chapter).
The specific mechanism by which the City shall
enter into an agreement with an outside user shall be by contract
of specified duration. All requirements of existing codes, laws and
ordinances, as currently amended, shall be secured via this contract.
[Added 6-3-1991]
A.
It is intended that the limitations expressed by § 253-68 above shall also apply to sewage, septage and slurries delivered to the City's wastewater treatment plant via any and all tankers permitted to convey such material by the New York State Department of Environmental Conservation. The outside user fee and collection system fee, however, does not apply to tanker-hauled sewage, septage and slurries. Fees required to enable the acceptance and treatment of tanker-hauled sewage, septage and slurries shall be as follows:
[Amended 4-4-1994; 7-1-1996; 6-19-2017]
(1)
Five and one-half cents ($0.055) per gallon for all
sewage, septage and slurries less than or equal to 5.6% solids by
weight.
(2)
For all leachate: five and one-half cents ($0.055)
per gallon.
(3)
Twelve cents ($0.12) per pound (dry weight) for all
deliveries over 5.6% solids by weight.
(4)
Minimum charge of $39.29 per delivery.
B.
The above fees are subject to adjustment by resolution
of the City Council of the City of Watertown should the cost of treatment
and disposal, in the opinion of the City Council, warrant such an
adjustment.
C.
All outside user sources and haulers will be required
to have a permit prior to acceptance of waste.
[Added 7-1-1996]
[Added 4-4-1994]
Any leachate deposited directly into the City
sewers by permit will be changed at the rate of $0.02 per gallon.

BOD surcharge
|
= 10% x $1,000
