§ 20-101. Surcharge for wastes of abnormal strength.

(a)

The service charge for any person discharging industrial wastes into the system is twenty-five (25) percent of the total cost of water purchased by the owner of that billing period; provided that, the city meter is the only source of water used by the owner, and; provided that, the B.O.D. in the wastewater or the suspended materials does not exceed the normal concentration of two hundred fifty (250) ppm.

(b)

When either the B.O.D. or the suspended solids or both are found to exceed the stated two hundred fifty (250) ppm at the point entering the city's system, a surcharge shall be applied to the billing rate by multiplying the normal base rate by the factor obtained from dividing the actual measured B.O.D. by two hundred fifty (250) and also by the factor obtained from dividing the actual measured suspended solids by two hundred fifty (250), each such factor to be applied individually and only when greater than one (1). The surcharge will be made for each factor that exceeds one (1) and shall be additive.

(c)

The determination of B.O.D. and suspended materials shall be by an independent laboratory selected by the city. The time of selection of the sample shall be at the sole discretion of the city. The applicable surcharge determined by such tests shall be retroactive for two (2) billing periods and shall continue for six (6) billing periods unless subsequent tests determine that the surcharge should be further increased.

(d)

When any such tests made at the discretion of the city show that a surcharge shall be applied, continued or increased over the base rates, whichever is applicable, then the owner shall be billed at the rate of five dollars ($5.00) for each test to cover the costs of sampling, mailing and handling plus the laboratory fees. When a surcharge is in effect, the test will be made at least once each fifteen (15) days. When such tests made at the discretion of the city reveal that the surcharge is no longer applicable, then no costs will be made to the owner for such test or tests.
