The laboratory determinations shall be made in accordance with procedures set forth in "Standard Methods".
BIOSOLIDS: Any discharge of water, sewage, 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 operation.
BUILDING: A structure which is built for permanent use; a house, garage, shed, store, etc.
BUILDING DRAIN: That part of the lowest horizontal piping of a drainage system which receives the discharge from soil, waste and other drainage pipes inside the walls of the building and conveys it to the building sewer, beginning five feet (5') outside the inner face of the building wall.
BUILDING SEWER: The extension from the building drain to the public sewer or other place of disposal.
EDU OR EQUIVALENT DWELLING UNIT: The basic cost unit for various fees and charges imposed in connection herewith. In the event that a given site, facility or person receiving service from the city shall have at a single service location more than one EDU, whether of the same or different type, a charge shall be imposed for each EDU.
ERU OR EQUIVALENT RESIDENTIAL UNIT: The basic cost unit for various fees and charges imposed in connection herewith. In the event that a given site, facility or person receiving service from the city shall have at a single service location more than one ERU, whether of the same or different type, a charge shall be imposed for each ERU.
GARBAGE: Solid wastes from the domestic and commercial preparation, cooking and dispensing of food, and from the handling, storage and sale of produce.
GREASE INTERCEPTOR: A vault with a minimum capacity of between five hundred (500) and seven hundred fifty (750) gallons that is located on the exterior of the building. The vault includes a minimum of two (2) compartments, and flow between each compartment is through a ninety degree (90°) fitting designed for grease retention. The capacity of the interceptor provides adequate residence time so that the wastewater has time to cool, allowing any remaining grease not collected by the traps time to congeal and rise to the surface where it accumulates until the interceptor is cleaned.
GREASE TRAP: A small reservoir built into the wastewater piping a short distance from the grease producing area. Baffles in the reservoir retain the wastewater long enough for the grease to congeal and rise to the surface.

A. A five (5) day biochemical oxygen demand greater than three hundred (300) parts per million by weight; or
B. More than three hundred fifty (350) parts per million of suspended solids by weight; or
C. Having an average daily flow greater than 0.20 percent of the average daily design flow of the city wastewater treatment plant.
INSPECTOR: The supervisor of sewer and/or water, or authorized deputy, agent or representative.

The process designed to remove pollutants from waste streams prior to discharge to the local sewer system.
PRODUCT: Any discharge of water, sewage, 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 operation.
PROPERLY SHREDDED GARBAGE: The wastes from the preparation, cooking and dispensing of food that have been shredded to such a degree that all particles will be carried freely under the flow conditions normally prevailing in public sewers, with no particle greater than one-half inch (1/2") in any dimension.
