(A) As an equitable share of the expenses incurred by the city in the construction, administration, operation, maintenance and replacement of the sewerage works, each user will pay to the city a quarterly amount based upon the following formula:
A = F(UC+DC)
Where: A = Service charge to user, with units of wastewater.
F = Volume of wastewater from user expressed in units of 1,000 gallons per quarter (often assumed equal to actual water usage).
UC = User charge.
DC = Debt service charge.
(B) Average city unit costs shall be computed annually, and shall include operation and maintenance costs (including replacement costs) and annual construction costs. Any industrial or other user which discharges pollutants which cause an increase in the cost of treatment and management of the effluent from the treatment plant shall be responsible for the payment of the increased costs. Each user of the city sewer system that does not have a metered source of water must install an accurate water or wastewater flow metering device (at user’s expense) that will serve as a basis for estimating the volume of wastewater discharged, and determining the sewer service charge. All users of city water that is not discharged to the city sanitary sewer system may install a separate water system and meter (one only in the same building as the main meter) to isolate and meter non-sewered water for which no sewer charge is required. If at any time after this independent system is installed, water from this system enters the sanitary sewer system, the user will be subject to the penalties of this section and shall be ordered to eliminate the independent system if this violation is continued.
(C) To ensure the required financial surveillance, the City Administrator shall annually review the cash flows associated with providing wastewater treatment service for the city, and shall report the findings to the Commission at the regular April meeting of each year. Any inequities and/or shortages of revenue caused by unforeseen changes in the cost revenue pattern of the wastewater treatment facilities shall be remedied immediately by a Commission resolution adjusting the unit cost figures. Adjusted unit figures shall be computed in accordance with this section and the methodology specified in the “Sewer Charge System Report for Glenwood and Long Beach” as approved by the State Pollution Control Agency.
(D) The Commission may adopt a policy for excluding summer-season non-sewered water usage (residential lawn and garden irrigation water) from the volume utilized in computing the residential sewer service charge.
