(A) (1) In order that the rates and charges may reflect the costs of providing service rendered to users, the town shall base its charges not only on the volume, but also the strength and character of the stronger than normal domestic sewage and wastes which it is required to treat and dispose of.
(2) The town shall require the user to determine the strength and content of all sewage and wastes discharged, either directly or indirectly, into the sanitary sewage system, in a manner and by a method as the town may deem practicable in order to determine the proper charge.
(B) The user shall furnish a central sampling point available to the town at all times.
(C) Normal sewage domestic waste strength should not exceed a biochemical oxygen demand of 200 milligrams per liter of fluid, suspended solids in excess of 250 milligrams per liter of fluid or ammonia nitrogen in excess of 30 milligrams per liter of fluid.
(D) (1) Additional charges for treating stronger- than-normal domestic waste shall be made on the following basis:
(a) There shall be an additional charge of $0.19 per pound of sewage or waste containing suspended solids in excess of 250 milligrams per liter of fluid.
(b) There shall be an additional charge of $0.23 per pound of sewage or waste having biochemical oxygen demand in excess of 200 milligrams per liter of fluid.
(c) There shall be an additional charge of $0.62 per pound of sewage or waste containing ammonia in excess of 30 milligrams per liter of fluid
(2) The determination of the concentration of suspended solids, five-day biochemical oxygen demand and ammonia nitrogen contained in the waste shall be in accordance with the latest copy 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, and in conformance with “Guidelines Establishing Test Procedures for the Analysis of Pollutants,” 40 CFR 136.
