(A) In order that the rates and charges may be justly and equitably adjusted to the service rendered to users, the town shall base its charges not only on the volume, but also on strength and character of the stronger-than-normal domestic sewage and shall require the user to determine the strength and content of all sewage and wastes discharged, either directly or indirectly into the sewage system, in such manner and by such method as the town may deem practicable in the light of the conditions and attending circumstances of the case, in order to determine the proper charge. The user shall furnish a sampling point, as defined in the Sewer Use Ordinance, available to the town at all times.
(B) Normal sewage domestic waste strength should not exceed a biochemical oxygen demand of 250 milligrams per liter of fluid or suspended solids in excess of 250 milligrams per liter of fluid. Additional charges for treating stronger-than-normal domestic waste shall be made on the following basis:
(1) Rate surcharge based upon suspended solids. There shall be an additional charge of $.22 per pound of suspended solids for suspended solids received in excess of 250 milligrams per liter of fluid.
(2) Rate surcharge based upon BOD. There shall be an additional charge of $.15 per pound of biochemical oxygen demand for BOD received in excess of 250 milligrams per liter of fluid.
(3) Rate surcharge based upon ammonia. There shall be an additional charge of $.68 per pound of ammonia for ammonia received in excess of 45 milligrams per liter of fluid.
(C) The determination of suspended solids and five-day Biochemical Oxygen Demand contained in the waste shall be in accordance with the current addition of Standard Methods for the Examination of Water, Sewage and Industrial Wastes, as written by the American Public Health Association, the American Water Works Association and the Water Pollution Control Federation.
