(A) In order that the rates and charges may be justly and equitably adjusted to the service rendered, the town shall base its charges not only on the volume, but also on the strength and character of the sewage and wastes which it is required to treat and dispose. The town shall require the owner or other 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 the light of the conditions and attending circumstances of the case, in order to determine the proper charge. The owner or other user shall furnish a central sampling point available to the town at all times.
(B) Extra charges based on the strength of the sewage and liquid wastes shall be made on the following basis.
(1) Rate surcharge based upon suspended solids. There shall be an additional charge of $0.06 per 1,000 gallons of flow for each 100 milligrams, or fraction thereof, of suspended solids in excess of 250 milligrams per liter of fluid.
(2) Rate surcharge based upon B.O.D. There shall be an additional charge of $0.07 per 1,000 gallons of flow for each 100 milligrams, or fraction thereof, of biochemical oxygen demand in excess of 200 milligrams per liter of fluid.
(C) To determine the strength of the sewage and wastes, samplings and analysis shall be made from time to time whenever it is deemed desirable by the town. After charges have been established based upon the strength of sewage and wastes, the owner may request reconsideration of these charges by the town by submitting analyses of composite samples of the sewage and wastes subject to charges, certified by a registered engineer or a qualified graduate chemist. The town may then adjust the charges to the chapter rates required by the analysis or may recheck the findings by additional samplings and analysis. Requests for rate adjustments by the owner may be submitted no more often than once every 12 months.
(D) The determination of suspended solids and five-day biochemical oxygen demand 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 Waterworks Association and the Water Pollution Control Federation.
