In any event, building sewer installation or repair shall be inspected by the City.
B. Proper Venting: Connection, or request for connection, to the public sewer shall constitute a representation that all of the system under the control and/or ownership of the sewer user is properly vented.
C. Discharge Restrictions: The use of the public sewers of the City shall be in accordance with the following:
1. No person shall discharge or cause to be discharged any storm water, ground water, roof run-off, subsurface drainage, uncontaminated cooling water or unpolluted industrial process waters to any sanitary sewer.
2. Storm water and all other unpolluted drainage shall be discharged to such sewers as specifically designated as storm water management system in compliance with other provisions of this Code. Industrial cooling water or unpolluted process waters may be discharged, on approval of the City and Health Department, to dry wells or other disposal areas.

a. Any gasoline, benzene, naphtha, fuel, oil or other flammable or explosive liquid, solid or gas, or any waste oil, grease or other petroleum product;
b. Any waters or wastes containing toxic or poisonous solids, liquids, organic chemicals or gases in sufficient quantity, either singly or by interaction with other wastes, to injure or interfere with any sewage disposal process, constitute any hazard to humans or animals, create a public nuisance or create any hazard in the receiving waters of the sewage treatment plant, including, but not limited to, cyanide in excess of two (2) milligrams per liter as CN in the wastes as discharged to the public sewer;
c. Any waters or wastes having a pH lower than five and five-tenths (5.5) or having any other corrosive property capable of causing damage or hazard to structures, equipment and personnel of the sewage works;
d. Any garbage other than properly shredded garbage;
e. Other wastes or solid or viscous substances which cause interference with the proper operation of the sewage works such as, but not limited to, ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastics, wood, whole blood, paunch manure, hair and fleshing, entrails, floatable oils, fat, grease, paper dishes, cups, milk containers, etc., either whole or ground by garbage grinders; (Ord. 349, 11-9-1993)
f. Substances, materials, waters or wastes, if it appears likely in the opinion of the City, Department of Health and Welfare or the Panhandle Health District that such wastes can harm either the sewers, sewage disposal process or equipment, having an adverse effect on the receiving stream or ground water, or can otherwise endanger life, limb, public property or constitute a nuisance. In forming its opinion as to the acceptability of these wastes, the City, Department of Health and Welfare and Health District will give consideration to such factors as the quantities of subject wastes in relation to flows and velocities in the sewers, materials of construction of the sewers, nature of the sewage process, capacity of the sewage disposal system, degree of treatability of wastes in the sewage disposal system and other pertinent factors. The substances prohibited are those items listed as hazardous wastes by the Environmental Protection Agency (EPA) in the EPA priority pollutant list or other substances deemed unacceptable by the City, the Panhandle Health District or the Idaho Department of Health and Welfare, Division of Environment.
D. Powers Of Director: If any waters or wastes are discharged or are proposed to be discharged to the public sewers, which waters contain the substances or possess the characteristics enumerated in subsection C of this Section and which, in the judgment of the Director, may have a deleterious effect upon the wastewater facilities, processes, equipment or receiving waters or which otherwise create a hazard to life or constitute a public nuisance, the Director may: (Ord. 349, 11-9-1993; 1997 Code)
1. Reject the wastes.
2. Require the pretreatment to an acceptable condition for discharge to the public sewers.
3. Require equalization of waste flows to acceptable levels for discharge to the public sewers.
4. Require payment to cover the added cost of handling and treating the wastes not covered by sewer user charges established herein. (Ord. 349, 11-9-1993)
When considering the above alternatives, the Director shall give consideration to the economic impact of each alternative on the discharger. If the Director permits the pretreatment or equalization of waste flows, the design and installation of the plants and equipment shall be subject to the review and approval of the Director. (Ord. 349, 11-9-1993; 1997 Code)
E. Requirements For Compliance Determination: The Director may require a user to provide information needed to determine compliance with this Chapter. These requirements may include:
1. Wastewater discharge peak rate and volume over a specified time period.
2. Chemical analyses of wastewaters.
3. Information on raw materials, processes and products affecting wastewater volume and quality.
4. Quantity and disposition of specific liquid sludge, oil, solvent or other materials important to sewer use control.
5. A plot plan of sewers on the user's property showing sewer and pretreatment facility location.
6. Details of wastewater pretreatment facilities.
7. Details of systems to prevent and control the losses of materials through spills to the Municipal sewer.
F. Measurements, Tests, Analyses: All measurements, tests, analyses of the characteristics of waters and wastes to which reference is made in this Chapter shall be determined in accordance with the latest edition of "Standard Methods for the Examination of Water and Wastewater", published by the American Public Health Association. Sampling methods, locations, times, durations and frequencies are to be determined on an individual basis subject to approval by the Director.
G. Special Agreement Or Arrangement: No statement contained in this Chapter shall be construed as preventing any special agreement or arrangement between the City and any industrial concern whereby an industrial waste of unusual strength, character or volume may be accepted by the City for treatment.
