(c)   Any gasoline, benzene, naphtha, fuel oil or other flammable or explosive liquid, solid or gas.

(d)   Any garbage that has not been properly shredded.

(e)   Any ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastics, wood, paunch manure or any other solid or viscous substance capable of causing obstruction of the sewage works.

(g)   Any waters or wastes containing a toxic or poisonous substance in sufficient quantity to injure or interfere with any sewage treatment process, constitute a hazard to humans or animals or create any hazard in the receiving waters of the sewage treatment plant.

(h)   Any waters or wastes containing suspended solids of such character and quantity that unusual attention or expense is required to handle such materials at the sewage treatment plant.

(i)    Any noxious or malodorus gas or substance capable of creating a public nuisance.

(Prior Code 13-603; Code 2023)

Grease, oil and sand interceptors or traps shall be provided in all filling stations, public garages and other commercial buildings where vehicles are washed or serviced, and in all other commercial or industrial buildings, when, in the opinion of the Superintendent they are necessary for the proper handling of liquid wastes containing grease in excessive amounts or any flammable wastes, sand and other harmful ingredients; except that such interceptors or traps shall not be required for private living quarters or dwelling units. All interceptors or traps shall be of a type and capacity approved by the Superintendent, and shall be located as to be readily and easily accessible for cleaning and inspection. Grease and oil interceptors or traps shall be constructed of impervious materials capable of withstanding abrupt and extreme changes in temperature. They shall be of substantial construction, watertight and equipped with easily removable covers which when bolted in place shall be gastight and watertight.

(Prior Code 13-605; Code 2023)

The admission into the public sewers of any waters or wastes having:

(a)   A 5-day Biochemical Oxygen Demand greater than three hundred (300) parts per million by weight; or

(c)   Containing any quantity of substances having the characteristics described in Section 13-603; or

Shall be subject to the review and approval of the Superintendent.

Where necessary in the opinion of the Superintendent, the owner shall provide, at his expense, such preliminary treatment as may he necessary to:

(a)   Reduce the Biochemical Oxygen Demand to three hundred (300) parts per million and the suspended solids to three hundred fifty (350) parts per million by weight; or

(b)   Reduce objectionable characteristics or constituents to within the maximum limits provided for in Section 16-603; or

(c)   Control the quantities and rates of discharge of such water or wastes.

Plans, specifications and any other pertinent information relating to proposed preliminary treatment facilities shall be submitted for approval of the Superintendent and the Kansas State Board of Health and no construction of such facilities shall be commenced until said approvals are obtained in writing.

When required by the Superintendent, the owner of all property served by a building sewer carrying industrial wastes shall install a suitable control manhole in the building sewer to facilitate observation, sampling and measurement of the wastes. Such manhole, when required, shall be accessibly and safely located, and shall be constructed in accordance with plans approved by the Superintendent. The manhole shall be installed by the owner at his expense and shall be maintained by him, at his expense, so as to be safe and accessible at all times.

(Prior Code 13-608; Code 2023)

All measurements, tests and analyses of the characteristics of water and wastes to which reference is made in Section 16-603 and 16-606 shall be determined in accordance with “Standard Methods for the Examination of Water and Sewage” and shall be determined at the control manhole provided for in Section 16-605, or upon suitable samples taken at said 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.

(Prior Code 13-609; Code 2023)

No statement contained in this article shall be construed as preventing any special agreement or arrangement between the City and any industrial waste of unusual strength or character may be accepted by the City for treatment, subject to payment therefor by the industrial concern.
