(A) 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 § 51.088, and which in the judgment of the Inspector may have a deleterious effect upon the sewage works, processes, equipment or receiving waters, or which otherwise create a hazard to life or constitute a public nuisance, the Inspector may:
(1) Reject the wastes;
(2) Require pretreatment to an acceptable condition for discharge to the public sewers;
(3) Require control over the quantities and rates of discharge; and/or
(4) Require payment to cover the added cost of handling and treating the wastes not covered by existing taxes or sewer charges under the provisions of § 51.094.
(B) If the Inspector 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 Inspector and subject to the requirements of all applicable codes, ordinances and laws.
(Ord. 304, passed 4-7-1975)
Grease, oil and sand interceptors shall be provided when, in the opinion of the Inspector, they are necessary for the proper handling of liquid wastes containing grease in excessive amounts, or any flammable wastes, sand or other harmful ingredients; except, that the interceptors shall not be required for private living quarters or dwelling units. All interceptors shall be of a type and capacity approved by the Inspector and shall be located as to be readily and easily accessible for cleaning and inspection.
(Ord. 304, passed 4-7-1975)
When required by the Inspector, the owner of any property serviced by a building sewer carrying industrial wastes shall install a suitable control manhole together with the necessary meters and other appurtenances in the building sewer to facilitate observation, sampling and measurement of the wastes. The manhole, when required, shall be accessibly and safely located and shall be constructed in accordance with plans approved by the Inspector. The manhole shall be installed by the owner at his or her expense and shall be maintained by him or her so as to be safe and accessible at all times.
(Ord. 304, passed 4-7-1975)
All measurements, tests and analysis 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, and shall be determined at the control manhole provided, or upon suitable samples taken at the control manhole. In the event that no special manhole has been required, the control manhole shall be considered to be the nearest downstream manhole in the public sewer to the point at which the building sewer is connected. Sampling shall be carried out by customarily accepted methods to reflect the effect of constituents upon the sewage works and to determine the existence of hazards to life, limb and property. (The particular analyses involved will determine whether a 24-hour composite of all outfalls of a premises is appropriate or whether a grab sample or samples should be taken. Normally, but not always, BOD and suspended solids analyses are obtained from 24-hour composites of all outfalls, whereas pH’s are determined from periodic grab samples.)
(Ord. 304, passed 4-7-1975)
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 or character may be accepted by the city for treatment, subject to payment therefore by the industrial concern.
(Ord. 304, passed 4-7-1975)
PROTECTION FROM DAMAGE
No unauthorized person shall maliciously, wilfully or negligently break, damage, destroy, uncover, deface or tamper with any structure, appurtenance or equipment which is a part of the sewage works. Any person violating this provision shall be subject to immediate arrest under charge of disorderly conduct.
