(A) In order that the rates and charges may be justly and equitably adjusted to the services rendered, the village shall have the right to base its charges not only on the volume, but also on the strength and character, of the wastes which it is required to treat and to dispose of.
(B) The village shall have the right to measure and to determine the strength and content of all wastes discharged, either directly or indirectly, into the village sewerage system, in such manner and by such method as it may deem practicable in the light of the conditions and attending circumstances of the case, in order to determine the proper charge.
(C) Extra charges or surcharges based on the strength of the liquid wastes shall be made in the following manner.
(1) For suspended solids in excess of two pounds for each 1,000 gallons of wastes, an additional charge shall be made at the rate of $0.04 per 1,000 gallons for each such excess pound. For five-day biological oxygen demand (B.O.D.) in excess of 1.75 pounds for each 1,000 gallons of wastes, an additional charge shall be made at the rate of $0.04 per 1,000 gallons for each such excess pound.
(2) For other solubles, such as oil and grease, in excess of 50 parts per million on an average basis, or 100 parts per million on a peak or catch sample basis, an additional charge shall be made at the rate of $0.04 per 1,000 gallons for each such excess pound. No wastes containing chromium or cyanide compounds shall be discharged into the sanitary sewerage system.
(3) To determine the strength of wastes, samplings and analyses may be made from time to time and whenever it is deemed desirable by the village. After charges have been established, based on the strength of the wastes, the owner may request reconsideration of the charges by the village by submitting, if requested, analyses of composite samples of the wastes, certified by a registered engineer or a graduate chemist, subject to such charges. The village may then adjust the charges to the rates as required by such analysis or may recheck the findings by additional sampling and analysis. Requests for rate adjustments may be submitted no more often than once in every 12-month period.
(D) The determination of suspended solids and five-day B.O.D. contained in the wastes shall be in accordance with the latest edition of Standard Methods for Examination of Water, Sewage and Industrial Wastes, as published by the American Public Health Association, the American Waterworks Association and the Federation of Sewage and Industrial Wastes Association.
(E) The charges established in this section and in § 53.03 are minimum charges, not maximum charges, and the village reserves the right and is obligated to increase the same at any time should revenues of the sewerage system prove to be insufficient to pay the operating and maintenance expenses and the debt service charges of the bonds issued to pay the costs of extending and improving such system, and to refund outstanding bonds.
