For the purpose of this subchapter, the following definitions shall apply unless the context clearly indicates or requires a different meaning.
APPROVING AUTHORITY. The City Manager or duly authorized representative.
B.O.D. (BIOCHEMICAL OXYGEN DEMAND). The quantity of oxygen by weight expressed in mg/l, utilized in the biochemical oxidation of organic matter under standard laboratory conditions for five days at a temperature of 20°C.
BUILDING SEWER. The extension from the building drain to the public sewer or other place of disposal (also called house lateral and house connection).
CITY. The City of Mount Pleasant, Texas, or any authorized person acting on its behalf.
C.O.D. (CHEMICAL OXYGEN DEMAND). Measures of the oxygen consuming capacity of inorganic and organic matter present in the water or waste water expressed in mg/l as the amount of oxygen consumed from a chemical oxidant in a specific test, but not differentiating between stable and unstable organic matter and thus not necessarily correlating with biochemical oxygen demand.
CONTROL MANHOLE. A manhole giving access to a building sewer at some point before the building sewer discharge mixes with other discharges in the public sewer.
CONTROL POINT. A point of access to a course of discharge before the discharge mixes with other discharges in the public sewer.
DIRECTOR OF UTILITIES. The Director of Utilities of the city, or his or her duly authorized deputy, agent or representative.

INDUSTRIAL WASTE CHARGE. The charge made on those persons who discharge industrial wastes into the city’s sewerage system.
MILLIGRAMS PER LITER (mg/l). The same as parts per million and is a weight-to-volume ratio; the milligram-per-liter value multiplied by the factor 8.34 shall be equivalent to pounds per million gallons of water.
NATURAL OUTLET. Any outlet into a watercourse, ditch, lake or other body of surface water or groundwater.
NORMAL DOMESTIC WASTE WATER. Waste water excluding industrial waste water discharged by a person into sanitary sewers and in which the average concentration of total suspended solids is not more than 200 mg/l and B.O.D. is not more than 250 mg/l.
OVERLOAD. The imposition of organic or hydraulic loading on a treatment facility in excess of its engineered design capacity.
PERSON. Includes a corporation, organization, government or governmental subdivision or agency, business trust, estate trust, partnership, association and any other legal entity.
pH. The reciprocal of the logarithm (base 10) of the hydrogen ion concentration expressed in grams per liter.
PUBLIC SEWER. Pipe or conduit carrying waste water or unpolluted drainage in which owners of abutting properties shall have the use subject to control by the city.
SANITARY SEWER. A public sewer that conveys domestic waste water or industrial wastes or a combination of both and into which storm water, surface water, groundwater and other unpolluted wastes are not intentionally passed.
SLUG. Any discharge of water, waste water or industrial waste which in concentration of any given constituent or in quantity of flow exceeds for any period of duration longer than 15 minutes more than five times the average 24-hour concentration or flows during normal operation.
STANDARD METHODS. The examination and analytical procedures set forth in the latest edition, at the time of analysis of Standard Methods for the Examination of Water and Waste Water, as prepared, approved and published jointly by the American Public Health Association, the American Water Works Association and the Water Pollution Control Federation.
STORM SEWER. A public sewer which carries storm and surface waters and drainage and into which domestic waste water or industrial wastes are not intentionally passed.
STORM WATER. Rainfall or any other forms of precipitation.
SUSPENDED SOLIDS. Solids measured in mg/l that either float on the surface of or are in suspension in water, waste water or other liquids and which are largely removable by a laboratory filtration device.
TO DISCHARGE. Includes to deposit, conduct, drain, emit, throw, run, allow to seep or otherwise release or dispose of or allow, permit or suffer any of these acts or omissions.
TRAP. A device designed to skim, settle or otherwise remove grease, oil, sand, flammable wastes or other harmful substances.
UNPOLLUTED WASTE WATER. Water containing:
(1) No free or emulsified grease or oil;
(2) No acids or alkalies;
(3) No phenols or other substances producing taste or odor in receiving water;
(4) No toxic or poisonous substances in suspension, colloidal state or solution;
(5) No noxious or otherwise obnoxious or odorous gases;
(6) Not more than ten mg/l each of suspended solids and B.O.D.; and
(7) Color not exceeding 50 units as measured by the Platinum-Cobalt method of determination as specified in Standard Methods.
WASTE. Rejected, unutilized or superfluous substances in liquid, gaseous or solid form resulting from domestic, agricultural or industrial activities.
WASTE WATER. A combination of the water-carried waste from residences, business buildings, institutions and industrial establishments, together with any ground, surface and storm water that may be present.
WASTE WATER FACILITIES. Includes all facilities for collection, pumping, treating and disposing of waste water and industrial wastes.
WASTE WATER TREATMENT PLANT. Any city-owned facilities, devices and structures used for receiving, processing and treating waste water, industrial waste and sludges from the sanitary sewers.
