(a) Plumbers. No person who does not have a state plumbing license shall do any plumbing or pipe fitting work in connection with the wastewater system.
(b) Tapping the mains.
(1) No person, except those having special permission from the village, or their agents, will be permitted, under any circumstances, to tap the village mains or laterals connecting with mains. The kind and size of connection with a main shall be that specified in the permit or order from the village.
(2) Mains and laterals shall always be tapped on the top half, and not within six inches (15 centimeters); of the joint, or within 24 inches (60 centimeters) of another lateral connection.
(c) Installation of laterals.
(1) All laterals on private property shall be installed in accordance with Wis. Admin. Code, Chapter SPS 382.
(2) Pursuant to Wis. Admin. Code, SPS 382.30, all laterals shall be inspected. Building sewer and private interceptor main sewers shall be inspected upon completion of placement of the pipe and before backfilling and shall also be tested before or after backfilling.
(d) Sanitary sewers. No person shall cause to be discharged any stormwater, surface drainage, groundwater, roof runoff, cooling water, unpolluted water, or incompatible pollutants into any sanitary sewer. No persons shall discharge or cause to be discharged the following described substances, materials, waters, or wastes if it appeals likely, in the opinion of the Approving Authority, that such wastes can harm either the wastewater collection system, wastewater treatment plant or equipment, have an adverse effect on the receiving stream, or may otherwise endanger life, limb, property, or constitute a nuisance. In forming an opinion as to the acceptability of these wastes, the Approving Authority will give consideration to the sewers, nature of the wastewater treatment process, capacity of the wastewater treatment plant, and other pertinent factors. The following substances are prohibited.
(1) Any gasoline, benzine, naptha, fuel oil, or other flammable or explosive liquid, solid, or gas.
(2) Any waters or wastes 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 wastewater treatment process, or constitute a hazard to humans or animals or create any hazard in the receiving waters of the wastewater treatment plant.
(3) Any waters or wastes having a pH lower than 6.0 or having any other corrosive property capable of causing damage or hazard to structures, equipment, and personnel of the wastewater treatment facility.
(4) Any waters or wastes having a pH in excess of 9.0.
(5) Solid or viscous substances in quantities or of such size capable of causing obstruction to the flow in sewers, or other interference with the proper operations of the wastewater collection and treatment facility such as, but not limited to, ashes, 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.
(6) Any liquid or vapor having a temperature higher than 150°F.
(7) Any water or waste containing fats, wax, grease, or oils in excess of 100 parts per million, whether emulsified or not which will or may cause obstruction to the flow in a sewer or other interference with the operation of the wastewater system.
(8) Any commercial garbage that has not been properly shredded (also referred to as “ground garbage”). The installation and operation of any commercial grinder equipped with a motor of one horsepower or greater shall be subject to the review and approval of the Approving Authority.
(9) Any waters or wastes containing iron, chromium, copper, zinc, mercury, and similar objectionable or toxic substances; or wastes exerting an excessive chlorine requirement to such a degree that in the opinion of the Approving Authority such materials received in the composite wastewater at the wastewater treatment facility exceed the limits established by the Approving Authority for such materials.
(10) Any waters or wastes containing phenols or other taste or odor producing substances in such concentrations exceeding limits which may be established by the Approving Authority as necessary after treatment of the composite wastewater, to meet the requirements of the state, federal, or other public agencies of jurisdiction for such discharge to the receiving waters.
(11) Any radioactive wastes or isotopes of such half-life or concentration as may exceed limits established by the Approving Authority in compliance with state or federal regulations.
(12) Any water or wastes which, by interaction with other water or wastes in the wastewater collection system, release obnoxious gases, form suspended solids which interfere with the collection system, or create a condition deleterious to structures and treatment processes.
(13) Materials which exert or cause:
a. Unusual B.O.D., chemical oxygen demand or chlorine requirements in such quantities as to constitute a significant load on the wastewater treatment facility;
b. Unusual volume of flow or concentration of wastes constituting “slugs” as defined herein;
c. Unusual concentrations of inert suspended solids (such as, but not limited to, fuller’s earth, lime slurries, and lime residues) or of dissolved solids (such as, but not limited to, sodium sulfate);
d. Excessive discoloration (such as, but not limited to, dye wastes and vegetable tanning solutions); and/or
e. 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 a degree that the Wastewater Treatment Facility effluent cannot meet the requirements of the Department of Natural Resources, Division of Environmental Protection of the state.
(e) Special arrangements. No statement contained in this chapter shall be construed as prohibiting any special agreement between the Approving Authority and any person whereby an industrial waste of unusual strength or character may be admitted to the wastewater treatment facility, either before or after pretreatment, provided that there is no impairment of the functioning of the wastewater treatment facility by reason of the admission of such wastes, and no extra costs required to treat the waste will be incurred by the Utility without recompense by the person.
