(18) "Public sewer" means a sewer provided by or subject to the jurisdiction of the City. It shall also include sewers within or outside the City boundaries that serve one or more persons and ultimately discharge into the City sanitary or combined sewer system, even though those sewers may not have been constructed with City funds.

(20) "Service charge" means the basic assessment levied on all users of the public sewer system whose wastes do not exceed in strength the concentration values established as representative of normal sewage, plus debt service.
(21) "Sewage" means the water-carried human, animal and household wastes in a public or private drain, and may include groundwater infiltration, surface drainage and industrial wastes.
(22) "Shall" is mandatory; "may" is permissive.
(23) "Slug" means any discharge of water, sewage or industrial waste which in concentration of any given constituent or in quantity of flow, exceeds for any period of longer duration than fifteen minutes, more than five times its average hourly concentration or flow.
(24) "Standard Methods" means the examination and analytical procedures set forth in the most recent edition of "Standard Methods for the Examination of Water, Sewage and Industrial Wastes", published jointly by the American Public Health Association, the American Water Works Association and the Federation of Sewage and Industrial Wastes Association.
(25) "Storm sewer" means a sewer that carries storm, surface and groundwater drainage but excludes sanitary sewage and industrial wastes.
