COLOR. The true color of the light transmitted by the waste solution after removing the suspended material, including the pseudocolloidal particles.
DOMESTIC WASTE. All liquid and waterborne pollutants, exclusive of unpolluted water as defined herein or wastewater or wastes from processes or operations in industrial establishments, as defined herein.
INDUSTRIAL WASTE. The liquid and waterborne pollutants resulting from processes or operations employed in industrial establishments, as defined in the Standard Industrial Classification Manual, 1972, Office of Management and Budget of the Federal Government, as amended and supplemented, under the following divisions:

INFILTRATION. Water other than wastewater that enters a sewerage system (including sewer service connections) from the ground through such means as defective pipes, pipe joints, connections, or manholes. INFILTRATION does not include, and is distinguished from, inflow.
INFILTRATION/INFLOW. The total quantity of water from both INFILTRATION and INFLOW without distinguishing the source.
INFLOW. Water other than wastewater that enters a sewerage system (including sewer service connections) from sources such as roof leaders, cellar drains, yard drains, area drains, foundation drains, drains from springs and swampy areas, manhole covers, cross connections between storm sewers and sanitary sewers, catch basins, cooling towers, storm waters, surface runoff, street wash waters, or drainage. INFLOW does not include, and is distinguished from, infiltration.
MANAGER. The Chief Administrative Officer of the town. As used herein it may also include any other town employee delegated to act for the town by the Manager or by the Town Board.
MAY. The act referred to is permissive.
NORMAL WASTE. A waste having an average concentration of 250 milligrams per liter of BOD, or less, and 250 milligrams per liter of suspended solids, or less, as determined by samples taken before entering the public sanitary sewers.
PERSON. Any individual, firm, company, association, corporation, governmental agency, board, commission, or municipal corporation other than the town.
pH. The logarithm of the reciprocal of the concentration of hydrogen ions in moles per liter of solution. Stabilized pH is that determined after a sample of the waste has been subjected to natural aeration.
PRIVATE WASTEWATER DISPOSAL SYSTEM. Any facility for wastewater treatment and disposal not maintained and operated by the town.
PROPERLY SHREDDED GARBAGE. The organic wastes resulting from the preparation, cooking, and dispensing of foods that have been shredded to a degree that all particles will be carried freely under the flow conditions normally prevailing in public sewers, with no particle being greater than one half inch in any dimension.
RECEIVING STREAM. The body of water, stream or watercourse receiving the discharge from a wastewater treatment plant, or the body of water, stream or watercourse formed by the effluent from a wastewater treatment plant.
REPLACEMENT. Expenditures for obtaining and installing equipment, accessories, or appurtenances which are necessary during the useful life of the treatment works to maintain the capacity and performance for which the works were designed and constructed. The term operation and maintenance includes REPLACEMENT.
SANITARY SEWER. A public sewer controlled by a governmental agency or public utility that carries liquid and waterborne wastes from residences, commercial buildings, industrial plants and institutions together with minor quantities of ground and surface waters that are not admitted intentionally.
SANITARY SEWERAGE SYSTEM. Any part of the public sanitary sewer or systems, including wastewater pumping stations, that discharge into wastewater treatment facilities owned and/or operated by the town.
SHALL. The act referred to is mandatory.
SLUG. Any discharge of water or wastewater of any duration during which the rate of flow, or concentration of any constituent increases to a magnitude as to adversely affect the operation of the sewer system or the ability of the town's wastewater treatment facilities to meet the water quality objectives.
STANDARD METHODS. The analytical procedures set forth in the latest edition of Standard Methods for the Examination of Water and Wastewater, published by the American Public Health Association, or EPA Methods of Chemical Analysis of Water and Wastes, as published by the Environmental Protection Agency, Water Quality in April 1971, or subsequent editions.
STORM SEWER. A sewer intended to carry only storm waters, surface runoff, street wash waters, and drainage.
STRENGTH OF WASTE. The concentration, expressed in milligrams per liter by weight, of a pollutant or substance contained in the liquid waste.
SUSPENDED SOLIDS. The total solid matter that either floats on the surface of, or is suspended in, water or liquid waste, and which is removable by laboratory filtration.
TOWN. The Town of Warsaw, North Carolina.
TREATMENT WORKS. Any devices and systems for the storage, treatment, recycling, and reclamation of sewage, domestic sewage, or liquid industrial wastes.
UNPOLLUTED WASTEWATER.
(a) Any wastewater which is substantially free of pollutants and is discharged from the following:
1. Rain downspouts and drains;
2. Footing drains;
3. Storm and surface water drains; and/or
4. Cooling water system.
(b) UNPOLLUTED WASTEWATER shall contain, by definition, none of the following:
1. BOD in excess of ten milligrams per liter;
2. Suspended solids in excess of ten milligrams per liter;
3. Free or emulsified greases or oils;
4. Acids or alkalies;
5. Phenols or other substances imparting taste or odor in receiving waters;
6. Toxic or poisonous substances;
7. Noxious or odorous gases; or
8. Temperature in excess of 150°F.
(c) UNPOLLUTED WASTEWATER shall also mean any wastewaters judged by the Department of Environment and Natural Resources of the state to be admissible to streams and water courses under the jurisdiction of the agency, and in accordance with the standards of water quality established by the agency for the particular stream or water course into which the unpolluted wastewater is to be discharged.
