The type, capacities, locations and layout of a private wastewater disposal system shall comply with all requirements and recommendations of the Kansas Department of Health and Environment and the Pottawatomie County Health Department. No permit shall be issued for any private wastewater disposal system employing subsurface soil absorption facilities where the area of the lot is less than that required by the current standards of the Pottawatomie County Health Department. No septic tank or cesspool shall be permitted to discharge to any natural outlet.
(Ord. 786, passed 2-1-1977)
(a) Storm water and all other unpolluted drainage shall be discharged to specifically designated storm sewers or to a natural outlet approved by the city and other regulatory agencies.
(b) Unpolluted industrial cooling water or process waters may be discharged, on approval of the city, to a storm sewer or natural outlet.
(Ord.786, passed - -)
No person(s) shall discharge or cause to be discharged any of the following described waters or wastes to any public sewers:
(a) Any storm water, surface water, ground water, roof runoff, subsurface drainage (including interior and exterior foundation drains), uncontaminated cooling water or unpolluted industrial process waters;
(b) Any gasoline, benzene, naphtha, fuel oil or other flammable or explosive liquid, solid or gas;
(c) Any waters containing toxic or poisonous solids, liquids or gases in sufficient quantity either singly or by interaction with other wastes, to injure or interfere with any waste treatment process, constitute a hazard to humans or animals, create a public nuisance or create any hazard in the receiving waters of the wastewater treatment plant;
(d) Any waters or waste having a pH lower than 5.5 or having any other corrosive property capable of causing damage or hazard to structures, equipment and personnel of the wastewater works;
(e) Solid or viscous substances in quantities or of such size as to be capable of causing obstruction to the flow in sewers, or other interference with the proper operation of the wastewater facilities such as, but not limited to, ashes, bones, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastics, wood, unground garbage, whole blood, paunch manure, hair and fleshings, entrails and paper dishes, cups, milk containers and the like, either whole or ground by garbage grinders.
(f) “Disposable wipes”, “flushable wipes”, “baby wipes” and similar named products, other than standard toilet paper;
(g) Any waters or wastes having:
(1) A five-day biochemical oxygen demand greater than 300 parts per million by weight;
(2) More than 350 parts per million by weight of suspended solids; or
(3) An average daily flow greater than two percent of the average sewage flow of the city, shall be subject to the review of the Superintendent.
(h) Where necessary in the opinion of the Superintendent, the owner shall provide at his or her expense, such preliminary treatment as may be necessary to:
(1) Reduce the biochemical oxygen demand to 300 parts per million by weight;
(2) Reduce the suspended solids to 350 parts per million by weight; or
(3) Control the quantities and rates of discharge of such waters or wastes.
(i) Plans, specifications and any other pertinent information relating to proposed preliminary treatment facilities shall be submitted for the approval of the Superintendent and no construction of such facilities shall be commenced until the approvals are obtained in writing; and
(j) Pretreatment or flow equalizing facilities shall be maintained continuously in satisfactory and effective operation by the owner at his or her expense.
(Ord. 786, passed 2-1-1977; Ord. 1647, passed 5-5-2015)
(a) (1) The following described substances, materials, waters or water shall be limited in discharges to the sewerage system to concentrations or quantities which will not harm either the sewers, wastewater treatment process or equipment, will not have an adverse effect on the receiving stream or will not otherwise endanger lives, limb, public property or constitute a nuisance.
(2) The city may lower these limitations where necessary to meet the above objectives. In forming an opinion as to acceptability, the city will give consideration to such factors as the quantity of subject waste in relation to flows and velocities in the sewers, materials of construction of the sewers, the wastewater treatment process employed, capacity of the wastewater treatment plant, degree of treatability of the waste in the wastewater treatment plant and other pertinent factors.
(b) The limitations or restrictions on materials or characteristics of waste or wastewater discharged to the sanitary sewer which shall not be violated without the approval of the city are as follows:
(1) Wastewater having a temperature higher than 150°F (65°C);
(2) Wastewater containing more than 25 milligrams per liter of petroleum oil, non-biodegradable cutting oils or products of mineral oil origin;
(3) Wastewater from industrial plants containing floatable oils, fat or grease;
(4) Any garbage that has not been properly shredded (see § 15-402). Garbage grinders may be connected to sanitary sewers from homes, hotels, institutions, restaurants, hospitals, catering establishments or similar places where garbage originates from the preparation of food in kitchens for the purpose of consumption on the premises or when served by caterers;
(5) Any waters or wastes containing iron, chromium, copper, zinc and similar objectionable or toxic substances to such degree that any such material received in the composite wastewater at the wastewater treatment works exceeds the limits established by the city for such materials;
(6) Any waters or wastes containing odor-producing substances exceeding limits which may be established by the city;
(7) Any radioactive wastes or isotopes of such half-life or concentration as may exceed limits established by the city in compliance with applicable state or federal regulations;
(8) Quantities of flow, concentrations, or both which constitute a slug as defined herein;
(9) Waters or wastes containing substances which are not amenable to treatment or reduction by the wastewater treatment processes employed, or are amenable to treatment only to such degree that the wastewater treatment plant effluent cannot meet the requirements of other agencies having jurisdiction over discharge to the receiving waters; and
(10) Any water or wastes which, by interaction with other water or wastes in the public sewer system, release obnoxious gases, form suspended solids which interfere with the collection system, or create a condition deleterious to structures and treatment processes.
