Disposal System. Any seepage pit, effluent irrigation system, soil absorption system, disposal trench, or other facility used in the disposal of wastewater, including any wastewater transmission lines, pumps, power, or other equipment associated with the ultimate disposal of wastewater, provided that the term shall not include any cesspool or injection well. Eligible Costs. Costs incurred after February 9, 2005.* Septic Tank. A watertight settling tank in which settled sludge is in immediate contact with the sewage flowing through the tank and the organic solids are decomposed by an anaerobic bacterial action. Wastewater. Has the same meaning as defined in § 43-1.2 . Editor’s note: * “ February 9, 2005” is substituted for “the effective date of this ordinance.”
