For the purpose of this chapter, the following definitions shall apply unless the context clearly indicates or requires a different meaning.
APPROVING AUTHORITY. The City Manager or his or her duly authorized representative.
B.O.D. or BIOCHEMICAL OXYGEN DEMAND. The quantity of oxygen by weight, expressed in mg/l, utilized in biochemical oxidation of organic 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 the HOUSE LATERAL or HOUSE CONNECTION).
CITY. The City of Canton, Texas, or any authorized person acting in its behalf.
C.O.D. (CHEMICAL OXYGEN DEMAND). The measure of the oxygen consuming capacity of inorganic and organic matter present in the water or wastewater 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 demand.
CONTROL MANHOLE. A manhole giving access to a building sewer at some point before it discharges in the public sewer.
CONTROL POINT. Point of access to a course of discharge before the discharge mixes with other discharges in the public sewer.
GARBAGE. Animal and vegetable wastes and residue from preparation, cooking and dispensing of food, and from the handling, processing, storage and sale of food products and produce.
INDUSTRIAL WASTE. Waste resulting from any process of industry, manufacturing, trade, business or from the development of any natural resource, or any mixture of the waste with water or normal domestic wastewater, or distinct from normal domestic wastewater.
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 part 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 course, ditch, lake or other body of surface water or ground water.
NORMAL DOMESTIC WASTEWATER. Wastewater excluding industrial wastewater discharged by a person is not sanitary sewer and in which the average concentration of total suspended solids is not more than 200 mg/l and B.O.D. is nor more than 200 mg/l.
OVERLOAD. The imposition of organic or hydraulic loading on a treatment facility in excess of its engineered design capacity.
PERSON. Any individual and includes any corporation, organization, government or governmental subdivision or agency, business trust, estate, trust, partnership, association or other legal entity.
pH. The logarithm (Base 10) of the reciprocal of the hydrogen ion concentration.
PUBLIC SEWER. Pipe or conduit carrying wastewater or unpolluted drainage in which owners or abutting properties shall have the use, subject to control by the City of Canton, Texas.
SANITARY SEWER. A public sewer that conveys domestic wastewater or industrial wastes or a combination of both, and into which storm water, surface water, ground water and other unpolluted wastes are not intentionally passed.
SLUG. Any discharge of water, wastewater 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 concentration of 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 Wastewater 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 wastewater or industrial wastes are not intentionally passed.
STORM WATER. Rainfall or any other forms of precipitation.
SUPERINTENDENT. The Water and Wastewater Superintendent of the City of Canton, Texas, or his or her duly authorized deputy, agent or representative.
SUSPENDED SOLIDS (SS). Solids measured in mg/l that either float on the surface, or are in suspension in, water, wastewater 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 to 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 WASTEWATER. Water containing:
(1) No free or emulsified grease or oil;
(2) No acids or alkalis;
(3) No phenols producing tastes or odor in receiving waters;
(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 an insignificant amount in mg/l each of suspended solids and B.O.D., as determined by the Texas Department of Water Resources; and
(7) Color not exceeding 50 units as measured by the platinum cobalt method of determinations as specified in Standard Methods.
WASTE. Rejected, unutilized or superfluous substances in liquid, gaseous or solid form resulting from domestic, agricultural or industrial activities.
WASTEWATER. A combination of the water from residences, business buildings, institutions and industrial establishments, together with any ground surface, and storm water that may be present.
WASTEWATER FACILITIES. Includes all facilities for collection, pumping, treating and disposing of wastewater and industrial wastes.
WASTEWATER SERVICE CHARGE. The charge on all users of the public sewer system whose wastes do not exceed in strength the concentration values established as representative of normal wastewater.
WASTEWATER TREATMENT PLANT. Any city-owned facilities, devices and structures used for receiving, processing and treating wastewater, industrial waste and sludges from the sanitary sewers.
WATER COURSE. A natural or human-made channel in which a flow of water occurs, either continuously or intermittently.
