(15) NORMAL SEWAGE means sewage that, when analyzed, shows by weight a daily average of not more than 280 parts per million of suspended solids, nor more than 240 parts per million of B.O.D. and/or 500 parts per million of C.O.D., nor more than eight parts per million of phosphorus, nor more than eighty parts per million of ether-soluble matter (grease and oil). These concentrations will be used for determining surcharges.
(16) OPERATION AND MAINTENANCE means all costs, direct and indirect, not including debt service, inclusive of, but not limited to, expenditures attributable to administration, the replacement of equipment, the purchase and installation of new equipment and the treatment and collection of waste waters, necessary to ensure adequate waste water collection and treatment on a continuing basis.

(19) SANITARY SEWER means a sewer which carries sewage and industrial waste, from residences, commercial buildings, industrial operations and institutions, to which storm, surface or ground water is not intentionally admitted.

(22) STORM WATER means any flow occurring during or following any form of natural precipitation and resulting therefrom.
(23) SURCHARGE means the assessment, in addition to the service charge, which is levied on those persons whose wastes are greater in strength than the concentrations established as representative of normal sewage.
(24) SUSPENDED SOLIDS means solids that either float on the surface of, or are in suspension in, water, sewage or other liquids, and which are removable by laboratory filtering.
(25) USER means any person who contributes, or causes or permits the contribution of, waste water into the village's publicly owned treatment works.
