(a) Sewer user charges, or rates, are imposed upon and shall be collected from the owner of each improved property which shall be connected with the sanitary sewer system, for use of the sewer system, whether such use shall be direct or indirect. The sewer user charges shall commence and shall be effective as of the date of connection of each such improved property to the sewer system or within 31 days of availability of the sewer system, whichever is first, and shall be payable as provided herein.
(b) The Superintendent is authorized to bill the customer for the cost of services performed at the request of the customer if the solution to the problem is known or found to be the responsibility of the customer.
(c) Every owner of improved property which is connected to the sewer system shall provide the city with and thereafter shall keep the city advised of his or her correct address. Failure of any person to receive bills for sewer user charges shall not be considered an excuse for nonpayment nor shall such failure result in an extension of the period of time during which the net bill shall be payable.
(d) Surcharge for high strength users: users discharging any water or wastes with a 30-day average BOD in excess of 300 milligrams per liter or a 30-day average suspended solids content in excess of 300 milligrams per liter or containing suspended solids with a character or quantity of pollutant requiring unusual attention or expense to handle or treat, shall pay, in addition to the base monthly sewer user charges, an additional surcharge (Cs) as determined by the following formula:
Cs = BC(B) + SC(S) + PC(P) Vu
Where:
B = Concentration of BOD from a user above a base level (300 mg/l);
BC = O & M cost for treatment of a unit for biochemical oxygen demand (BOD);
S = Concentration of suspended solids from a user above a base level (300 mg/l);
SC = O & M cost for treatment of a unit of suspended solids;
P = Concentration of any pollutant from a user above a base level;
PC = O & M cost for treatment of a unit of any pollutant; and
Vu = Volume contribution from a user per unit of time.
(e) Council shall review user charges annually and revise them periodically to reflect actual treatment works operation and maintenance costs.
