8-3-1: DEFINITIONS:

When used in this chapter, the following words and phrases shall have the meanings ascribed to them in this section:

   APPROVING AUTHORITY: The mayor or his duly authorized representative.

   BOD (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 (5) days at a temperature of twenty degrees centigrade (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).

   COD (CHEMICAL OXYGEN DEMAND): 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 oxygen demand.

   CITY: The city of Alamo, Texas, or any authorized person acting in its behalf.

   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.

   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 or business from the development of any natural resource or any mixture of the waste with water or normal wastewater or distinct from normal wastewater.

   INDUSTRIAL WASTE CHARGE: The charge made on those persons who discharge industrial wastes into the city's sewerage system.

   LRGVPCA: Lower Rio Grande Valley Pollution Control Authority.

   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 eight and thirty four one-hundredths (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 WASTEWATER: Wastewater, excluding industrial wastewater, discharged by a person into sanitary sewers and in which the average concentration of total suspended solids is not more than three hundred (300) mg/l and BOD is not more than two hundred (200) mg/l.

   OVERLOAD: The imposition of organic or hydraulic loading on a treatment facility in excess of its engineered design capacity.

pH: The logarithm (base 10) of the reciprocal of the hydrogen ion concentration expressed in grams per liter.

   PERSON: Includes corporation, organization, government or governmental subdivision or agency, business trust, estate, trust, partnership, association and any other legal entity.

   PUBLIC SEWER: Pipe or conduit carrying wastewater 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 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 fifteen (15) minutes, more than five (5) times the average twenty four (24) hour concentration of flows during normal operations.

   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 wastewater or industrial wastes are not intentionally passed.

   STORM WATER: Rainfall or any other forms of precipitation.

   SUPERINTENDENT: The Director of Public Works of the City of Alamo, Texas, or his duly authorized deputy, agent or representative.

   SUSPENDED SOLIDS: Solids, measured in mg/l, that either float on the surface of 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 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:

   A.   No free or emulsified grease or oil;

   B.   No acids or alkalis;

   C.   No phenols or other substances producing taste or odor in receiving water;

   D.   No toxic or poisonous substances in suspension, colloidal state or solution;

   E.   No noxious or otherwise obnoxious or odorous gases;

   F.   Not more than ten (10) mg/l each of suspended solids and BOD; and

   G.   Color not exceeding fifty (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.

   WASTEWATER: 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.

   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 LRGVPCA-owned facilities, devices and structures used for receiving, processing and treating wastewater, industrial waste and sludges from the sanitary sewers.

   WATERCOURSE: A natural or man-made channel in which a flow of water occurs, either continuously or intermittently. (Ord. 592, 9-16-75)

8-3-2: PROHIBITED DISCHARGES:

   A.   Harmful Waste: No person may discharge to the public sewers any waste which by itself or by interaction with other wastes may:

      1.   Injure or interfere with wastewater treatment processes or facilities;

      2.   Constitute a hazard to humans or animals; or

      3.   Create a hazard in receiving waters of the wastewater treatment plat effluent.

   B.   Conformance with Provisions: All discharges shall conform to the requirements of this Chapter. (Ord. 592, 9-16-75)
