Every house sewer from a point two feet outside the house to the street or alley shall be of standard vitrified clay sewer pipe not less than four inches in diameter unless laid less than 12 inches deep, in which event it shall be of standard cast iron sewer pipe or PVC schedule 40 not less than four inches in diameter. Each house or building must have a separate house sewer connecting the house or building directly with the city sewer system. When a house or building is constructed as a two- or more family unit, the sewer pipe shall be not less than six inches in diameter.

INDUSTRIAL WASTE DISCHARGE STANDARDS
For the purpose of this subchapter, the following definitions shall apply unless the context clearly indicates or requires a different meaning.
APPROVING AUTHORITY. The Mayor or his or her duly authorized representative.
BOD (BIOCHEMICAL OXYGEN DEMAND). The quantity of oxygen by weight, expressed in milligrams per liter, 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.)
COD (CHEMICAL OXYGEN DEMAND). A measure of the oxygen-consuming capacity of inorganic and organic matter present in the water or wastewater, expressed in milligrams per liter 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.
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 or 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.
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 ground water.
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 200 mg/l and BOD is not more than 200 mg/l.
OVERLOAD. The imposition of organic or hydraulic loading on a treatment facility in excess of its engineered design capacity.
pH. The measure of the relative acidity or alkalinity of water and is defined as the negative logarithm (base 10) of the hydrogen ion concentration.
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 15 minutes more than five times the average 24-hour concentration or flow 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 water and surface water and drainage, and into which domestic wastewater or industrial wastes are not intentionally passed.
STORM WATER. Rainfall or any other form of precipitation.
SUPERINTENDENT. The Water and Wastewater Superintendent of the city, or his or her duly authorized deputy, agent or representative.
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.
TOTAL SUSPENDED SOLIDS (TSS). Solids, measured in milligrams per liter, 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.
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 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 TSS and BOD; 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.
WASTEWATER. A combination of the water-carried waste from residences, business buildings, institutions and industrial establishments, together with any ground water, surface water and storm water that may be present.
WASTEWATER FACILITIES. 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.
WATERCOURSE. A natural or human-made channel in which a flow of water occurs, either continuously or intermittently.
(1998 Code, § 122-61) (Ord. 08-46, passed 11-19-2008)
