(A) 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 $0.86 per cubic feet of flow each 300 milligrams, or fraction thereof, of suspended solids in excess of 300 milligrams per liter of fluid.
(2) Rate surcharge based upon BOD. There shall be an additional charge of $.124 per 100 cubic feet of flow for each 100 milligrams, or fraction thereof, of biochemical oxygen demand in excess of 300 milligrams per liter of fluid.
(B) 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 city. After charges have been established based upon the strength of sewage and wastes, the owner may request reconsideration of these charges by the city by submitting analysis of composite samples of the sewage and wastes subject to such charges, certified by a registered engineer or a qualified graduate chemist. The city may then adjust the charges to the ordinance rates required by such analysis or may recheck the findings by additional samplings and analysis. Requests for rate adjustments by the owner may be submitted no more than once every 12 months.
(C) The determination of suspended solids and five-day bio-chemical 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 Water Works Association and the Water Pollution Control Federation.
(D) Except for billings to multiple users such as apartment houses, mobile home courts and housekeeping rooms, the rates and charges may be billed to the tenant or tenants occupying the properties served unless otherwise requested in writing by the owners, but such billings shall in no way relieve the owner from liability in the event payment is not made as herein required. The owners of the properties served which are occupied by tenants shall have the right to examine the collections records of the city for the purpose of determining whether such rates and charges have been paid by such tenants, provided that such examinations shall be made at the office at which said records are kept and during the hours that such office is kept open for business.
