For the purpose of this chapter the following definitions shall apply unless the context clearly indicates or requires a different meaning.

BIOCHEMICAL OXYGEN DEMAND (B.O.D.) The quantity of dissolved oxygen in milligrams per liter required during stabilization of the decomposable organic matter by aerobic biochemical action under standard laboratory procedures for five days at 20°C. The laboratory determinations shall be made in accordance with the procedures set forth in STANDARD METHODS.

BUILDING (or HOUSE) DRAIN. That part of the lowest horizontal piping of a building drainage system which receives the discharge from soil, waste, and other drainage pipes inside the walls of the building, and conveys it to a point approximately five feet outside the foundation wall of the building.

BUILDING (or HOUSE) SEWER. The pipe which is connected to the building (or house) drain at the point approximately five feet outside the foundation wall of the building, and which conveys the building's discharge from that point to the public sewer or other place of disposal.

CHEMICAL OXYGEN DEMAND (COD). A measure of the oxygen equivalent of that portion of the organic matter in a sample that is susceptible to oxidation by a strong chemical oxidant. The laboratory determination shall be made in accordance with procedures set forth in STANDARD METHODS.

CLEAN OUT. A vertical section of sewer pipe (usually capped) rising from the lateral as a point of service to clean the lateral.

COMBINED SEWER. A sewer intended to receive both wastewater and storm or surface water.

COMPATIBLE POLLUTANT. Biochemical oxygen demand, suspended solids, pH, and fecal coliform bacteria, plus pollutants identified in the NPDES Permit if the treatment works was designed to treat such pollutants, and in fact does remove such pollutants to a substantial degree. The term “substantial degree” is not subject to precise definition, but generally contemplates removals in the order of 80% or greater. Minor incidental removals in the order of 10% to 30% are not considered substantial. Examples of the additional pollutants which may be considered compatible include chemical oxygen demand; total organic carbon; phosphorus and phosphorus compounds; nitrogen and nitrogen compounds; and fats, oils, and greases of animal or vegetable origin (except as prohibited where these materials would interfere with the operation of the treatment works.)

EFFLUENT. The water, together with any wastes that may be present, flowing out of a drain, sewer, receptacle, or outlet.

FECAL COLIFORM. Any of a number of organisms common to the intestinal tract of man and animals, whose presence in sanitary sewage is an indicator of pollution.
