(A) The Director shall make and enforce rules and regulations establishing the types, amount, and characteristics of sewage and wastes discharged into the sanitary sewerage system; the types, amount, and characteristics of sewage and wastes admissible to the system after pretreatment; requisites for pretreatment; fees for review and approval of applications for service, pretreatment plans, engineering advice and studies, program administration, and the like for review of applications and enforcement of code provisions; and otherwise governing the discharge of sewage and wastes into the system in the interest of safety and efficient operation of the wastewater treatment plant.
(B) Any user must, upon a request of the Director, present to the Director for review and approval information sufficient for the Director to determine compliance with the provisions of this chapter, including, but not limited to:
(1) A chemical analysis of the wastes to be discharged to the sewerage system expressed in units acceptable to the Director, or if this is not available, the expected waste analysis based on similar processes now in operation together with a letter of agreement from the applicant that chemical analysis of the wastes is to be performed at applicant’s expense at a frequency and in accordance with a time frame established by the Director;
(2) A description of the characteristics of the wastes and an estimate of the amount of such wastes to be discharged to the sanitary sewer system expressed in units acceptable to the Director;
(3) A plan for pretreatment of any wastes that do not comply with the provisions of this chapter; and
(4) Any other data determined by the Director as necessary to determine compliance with the provisions of this chapter together with required fees for review and administration of the data.
(C) If at any time the character of sewage or waste from any user is such that, in the judgement of the Director, it will damage the sewerage system or cannot be treated satisfactorily at the wastewater treatment plant, the Director shall compel such users to prevent it from entering the sewerage system.
(D) In cases where the character of the sewage or waste or the volume of the sewage or waste from any user is such that, in the judgement of the Director, the waste or sewage imposes an unreasonable burden upon the sewage collection, pumping, or treatment works the Director may:
(1) Compel such user to treat such sewage in such manner as specified by the village before discharging it into the sewerage system;
(2) Require flow control or equalization of such wastes so as to avoid any slug loads or excessive flows that may be harmful to the treatment works;
(3) Require payment of a surcharge fee on any excessive flows or loadings discharged to the treatment works to cover the additional costs of having capacity for and treating such wastes; and/or
(4) Compel such user to prevent the waste from entering the sewerage system.
(E) (1) (a) The discharge of unacceptable wastewater into the sewerage system, whether directly or indirectly, is prohibited. Wastewater shall be deemed unacceptable when the concentration of regulated substances in the wastewater exceeds certain prescribed tolerable limits. Regulated substances include, but are not necessarily limited to, the following:
Tolerable Limits (mg/l)
Total dissolved solids
(b) Any wastewater containing any radioactive wastes or isotopes of such half-life or concentrations as exceed limits in compliance with applicable state or federal regulations.
(2) The preceding list of regulated substances is subject to revisions by the Director as required to meet desired plant operations guidelines, or current water quality standards or effluent standards imposed by state or federal agencies.
(F) No person shall discharge or cause to be discharged, either directly or indirectly to the sewerage system, any of the following described substances, materials, waters, or wastes:
(1) Any liquid or vapor having a temperature higher than 150°F., or that causes, in whole or part, the temperature of the influent to the wastewater system to exceed 104°F.;
(2) Any gasoline, benzene, naphtha, fuel, oil, mineral oil, or other volatile flammable or explosive liquid, solid, or gas;
(3) Any noxious or malodorous gas or substance which, either singly or by interaction with other wastes, is capable of creating a public nuisance or hazard to life or of preventing entry into the sewers for their maintenance and repair;
(4) Any waters or wastes having a pH lower than 5.5 or higher than 9.0, or having any corrosive property of causing damage or hazard to structures, equipment, or personnel of the sewerage system;
(5) Any ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastics, wood punch manure, hair, entrails, lime slurry, lime, plant residues, cannery wastes, bulk solids, or any other solid objects or viscous substance capable of causing obstruction to the flow operation of the sewerage system;
(6) Any waters or wastes containing a toxic or poisonous substance in sufficient quantity to inhibit or interfere with any sewerage treatment process, constitute a hazard to humans or animals, or create any hazard in the receiving waters of the sewerage system;
(7) Any water or wastes containing oil or grease exceeding, on analysis, an average of 50 milligrams of oil and grease per liter determined as total either soluble matter;
(8) Any garbage that has not been properly shredded to a degree that all particles will be carried freely under the flow conditions of the sewer and with no particle greater than one-half inch in any dimension;
(9) Any water or wastes containing suspended solids of such character or quality that unusual attention or expense is required to handle such materials at the sewage treatment plant, or having a chlorine demand greater than 25 ppm;
(10) Any waste containing substances that would result in a violation of the NPDES permit; and/or
(11) The above list is subject to revisions as required to meet current water quality standards imposed by the state or federal agencies.
(G) No statement contained in this section shall be interpreted as preventing any special agreement or arrangement between the village and any user whereby a waste of unusual strength or character may be accepted by the village for treatment. In all such cases, the procedures set forth in this chapter and the village ordinance establishing sewer service charges will be governing factors in any contracts entered into.
(H) (1) Grease, oil, and sand interceptors shall be provided when, in the opinion of the Director, they are necessary for proper handling of liquid wastes containing grease in excessive amounts, sand, and other harmful ingredients; except that such interceptors shall not be required for private living quarters or dwelling units. All interceptors shall be located as to be readily and easily accessible for cleaning and inspection.
(2) Grease and oil interceptors shall be constructed of impervious materials capable of withstanding abrupt and extreme changes in temperature. Interceptors shall be of substantial construction, water-tight, and equipped with easily removable covers which when bolted in place shall be gas-tight and water-tight. The Director shall review and approve the design of grease and oil interceptors prior to construction.
(3) Where installed, all grease, oil, and sand interceptors shall be maintained by the owner at his or her expense in continuous efficient operation at all times.
