A.Â
Sewer users served by Light and Water Utility water meters.
There is hereby levied and assessed upon each lot, parcel of land, building,
or premises having a connection with the wastewater system and being served
with water solely by the Light and Water Utility a wastewater treatment service
charge based, in part, on the quantity of water used as measured by the Light
and Water Utility water meter used upon the premises.
B.Â
Sewer users served by private wells. If any person discharging
sewage into the public sanitary sewer system procures any part or all of his
water from sources other than the Light and Water Utility, all or part of
which is discharged into the public sanitary sewer system, the person shall
be required to have water meters installed for the purpose of determining
the volume of water obtained from these other sources. Where sewage meters
are already installed, the water meters will not be required. The water meters
may be furnished by the Light and Water Utility and installed under its supervision,
all costs including the cost of the meter being at the expense of the person
requiring the meter.
A sewer service charge is hereby imposed upon each lot, parcel of land,
building, or premises served by the sewerage system, or otherwise discharging
sewage, including industrial wastes, into the sewerage system. Such sewer
service charge shall be payable as hereinafter provided, and in an amount
determinable as follows:
A.Â
The sewer service charge for any lot, parcel of land,
building, or premises within the corporate limits, and for any lot, parcel
of land, building or premises outside the corporate limits which is connected
to the sanitary sewer system, shall be based upon the quantity of water used
therein or thereon and quality of wastewater generated as measured by the
water meter or sewage meter in use as follows:
(1)Â
Category A is defined as normal or domestic strength
wastewater having organic concentrations of biochemical oxygen demand (BOD)
no greater than 558 milligrams per liter (mg/l), total suspended solids concentrations
no greater than 558 mg/l, total kjeldahl nitrogen (TKN) concentrations no
greater than 74 mg/l, and total phosphorus concentrations no greater than
13 mg/l. See Appendix B, User Charge System Calculations, for methods used
to calculate Category A charge rates.[1]
(a)Â
The general format for the sewer service charge for Category
A wastewater is as follows:
Category A Sewage | |||
|---|---|---|---|
TCA = FSC + VCA x V | |||
Where: | |||
TCA | = | Total monthly sewer service charge for Category A wastewater | |
FSC | = | Fixed service charge per user per month | |
VCA | = | Volume unit price in dollars per 1,000 gallons | |
V | = | Volume of wastewater per month in units of 1,000 gallons | |
[1]
Editor's Note: Appendix B is on file at the office of the City Clerk.
(2)Â
Category B is defined as high-strength wastewater
having organic concentration of biochemical oxygen demand (BOD) greater than
558 milligrams per liter (mg/l), total suspended solids concentrations greater
than 558 mg/l, total kjeldahl nitrogen (TKN) concentrations greater than 74
mg/l, or total phosphorus concentration greater than 13 mg/l.
(a)Â
The general format for the sewer service charge for Category
B wastewater is as follows.
Category B Sewage | |||
|---|---|---|---|
TCB = TCA + (Surcharge
x V) | |||
Where: | |||
TCB | = | Total monthly sewer service charge for Category B wastewater | |
TCA | = | Total monthly sewer service charge for Category A wastewater | |
Surcharge = [BOD x CBOD + TSS x CTSS
+ TKN x CTKN + P x CP] | |||
Where: | |||
BOD | = | Pounds of BOD in excess of normal strength domestic wastewater | |
CBOD | = | Cost per pound of BOD | |
TSS | = | Pounds of TSS in excess of normal strength domestic wastewater | |
CTSS | = | Cost per pound of TSS | |
TKN | = | Pounds of TKN in excess of normal strength domestic wastewater | |
CTKN | = | Cost per pound of TKN | |
P | = | Pounds of phosphorus in excess of normal strength domestic wastewater | |
CP | = | Cost per pound of phosphorus | |
V | = | Volume of wastewater per month in units of 1,000 gallons | |
(3)Â
Category C is defined as septage which has organic concentrations of biochemical oxygen demand (BOD) greater than 558 milligrams per liter (mg/l), total suspended solids concentration greater than 558 mg/l, total kjeldahl nitrogen (TKN) concentrations greater than 74 mg/l or total phosphorus concentrations greater than 13 mg/l. Sewer service charges for Category C wastewater shall be determined and collected pursuant to Article III of this chapter (pertaining to on-site waste disposal at the Lodi wastewater treatment plant).
(4)Â
A discount will be granted from the volume charge for
any sewer service users who account for metered water used for irrigation,
air conditioning, steam generating, cooling, ice rinks, or other purposes
which are not discharged into the sanitary sewer system. To qualify for the
discount, a meter for such diverted water usage must be installed and maintained
at the expense of the user (including the cost of the meter, installation
and maintenance), with the type of meter and method of installation to be
approved by the City. The discount will be based on the amount of water so
diverted from the sanitary sewer system.
B.Â
Reassignment of sewer users. The approving authority
will reassign sewer users into appropriate sewer service charge categories
if wastewater sampling programs and other related information indicate a change
of categories is necessary.
C.Â
On-site waste disposal. Charges for on-site waste disposal, including but not limited to disposal of septage and holding tank waste (as theses terms are defined in Article III, § 272-20 of this chapter), shall be determined and collected pursuant to Article III of this chapter (pertaining to on-site waste disposal at the Lodi wastewater treatment plant).
A.Â
Method of billing. The sewer service charge shall be
payable to the City Treasurer in such manner as may be directed from time
