(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 practical in light of the conditions and attending circumstances of the case, in order to determine the proper charge. The user shall furnish a control manhole suitably located and available to the town at all times.
(B) (1) Normal sewage domestic waste strength should not exceed a total biochemical oxygen demand of 250 milligrams per liter of fluid, or total 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.
(a) Rate surcharge based upon total suspended solids. There shall be an additional charge of $0.12 per pound of total suspended solids for total suspended solids received in excess of 225 milligrams per liter of fluid.
(b) Rate surcharge based upon TBOD. There shall be an additional charge of $0.12 per pound of total biochemical oxygen demand for TBOD received in excess of 200 milligrams per liter of fluid.
(2) The determination of total suspended solids and five-day total biochemical oxygen demand contained in the waste shall be in accordance with the most current edition 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.
