§ 50.04 BUILDING SEWERS AND CONNECTIONS.
   (A)   No unauthorized person shall uncover, make any connections with or openings into, alter, or disturb any public sewer or appurtenance thereof without first obtaining a written permit therefor from the local agency. No building sewer shall be covered until after it has been inspected and approved by the authorized official. The cost of the application and permit shall be $10.
   (B)   All costs and expense incident to the installation and connection of the building sewer to the public sewer connection shall be borne by the owner.
   (C)   A separate and independent building sewer shall be provided for every building.
   (D)   Old building sewers may be used in connection with the new buildings only when they are found on examination and test to meet all requirements of this chapter.
   (E)   A newly constructed building sewer shall be schedule 40 PVC, cast iron, vitrified clay sewer pipe, or asbestos cement pipe. Joints shall be tight and waterproof. Materials and joints shall be as approved by the local agency. Any part of the building sewer that is located within ten feet of a water service pipe shall be constructed of cast iron. If installed in filled or unstable ground, the building sewer shall be of cast iron soil pipe, except that non-metallic material may be accepted if laid on a suitable concrete bed or cradle. Transitions or connections will be constructed only with fabricated connection fittings approved by the local agency.
   (F)   The size and slope of the building sewer shall be subject to the approval of the local agency, but in no event shall the diameter be less than six inches. The slope of such six-inch pipe shall not be less than one-eighth inch per foot, unless otherwise permitted.
   (G)   Whenever possible, the building sewer shall be brought to the building at an elevation below the basement floor. No building sewer shall be laid parallel to or within three feet of any bearing wall, which might thereby be weakened. The depth shall be sufficient to afford protection from frost. The building sewer shall be laid at uniform grade and in a straight line.
   (H)   In all buildings in which any building drain is too low to permit gravity flow to the public sewer, sanitary sewage carried by such drain shall be lifted by a pumping system approved by the local agency and discharged to the building sewer.
   (I)   No sewer connection will be permitted unless there is capacity available in all downstream sewers, lift stations, force mains, and the sewage treatment plant, including capacity for treatment of BOD and suspended solids.

§ 50.05 USE OF PUBLIC SEWERS.
   (A)   No person shall discharge or cause to be discharged any storm water, surface water, ground water, water from footing drains, or roof water to any sanitary sewer or sewer connection except as otherwise provided in this chapter. Downspouts and roof leaders shall be disconnected from sanitary sewers within one year of the date of this chapter.
   (B)   Storm water, ground water, water from footing drains, and all other unpolluted drainage shall be discharged into such sewers as are specifically designated as storm sewers, or to a natural outlet, except as otherwise provided in this chapter. Industrial cooling water or unpolluted process waters may be discharged, upon application and approval of the local agency and the appropriate state agency, to a storm sewer or natural outlet.
   (C)   Except as hereinafter provided, no person shall discharge or cause to be discharged any of the following described waters or wastes to any public sewer:
      (1)   Any liquid or vapor having a temperature higher than 150°F (66°C) or lower than 32°F (0°C);
      (2)   Any water or waste which may contain more than 100 parts per million by weight of fat, oil, or grease;
      (3)   Any gasoline, benzine, naphtha, fuel, oil, or other flammable or explosive liquid, solid, or gas;
      (4)   Any garbage that has not been properly shredded;
      (5)   Any ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastic, woods, paunch manure, or other solid or viscous substance capable of causing obstruction to flow in sewers or other interference with the proper operation of the sewerage works;
      (6)   Any waters or wastes having corrosive properties capable of causing drainage hazard to structures, equipment, and personnel of the sewerage works;
      (7)   Any waters with a pH lower than 6.5 or greater than 9.5;
      (8)   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 treatment plant;
      (9)   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;
      (10)   Any noxious or malodorous gas or substance capable of creating a public nuisance; and/or
      (11)   Any industrial waste that may cause a deviation from the NPDES permit requirements, pretreatment standards, and other state or federal regulations.
   (D)   Grease, oil, and sand interceptors shall be provided when liquid wastes contain grease in excessive amounts, or other harmful ingredients, except that such interceptors shall not be required for single-family or multiple-family dwelling units. All interceptors shall be of a type and capacity approved by the local agency and shall be located as to be readily and easily accessible for cleaning and inspection. Grease and oil interceptors shall be constructed of impervious materials capable of withstanding abrupt and extreme changes in temperature. They shall be of substantial construction, water-tight, and equipped with easily removable covers which, when bolted into place, shall be gas-tight and water-tight.
   (E)   Where installed, all grease, oil, and sand interceptors shall be maintained by the owner, at his or her expense, in continuously efficient operation at all times.
   (F)   (1)   The admission into the public sewers of any waters or wastes containing more than 250 mg/l of BOD or 300 mg/l of suspended solids, or containing any quantity of substances having the characteristics described in division (C) above, having an average daily flow greater than 2% of the average daily flow of the local agency, shall be subject to review and approval of the local agency. Preliminary treatment shall be provided at no expense to the local agency as may be necessary to reduce the BOD to 250 mg/l and suspended solids to 300 mg/l, or to reduce objectionable characteristics for constituents to within the maximum limits provided for in division (C) above, or to control the quantity and rates of discharges of such waters or wastes. A person may be required to remove, exclude, or require pretreatment of any industrial waste in whole or in part for any reasons deemed to be in the interest of the local agency. Where preliminary treatment facilities are provided for any waters or wastes, they shall be maintained in satisfactory and effective operation by the owner at his or her expense. Plans, specifications, and any other pertinent information relating to proposed preliminary treatment facilities shall be submitted for approval, and no construction of any facility shall be commenced until said approvals are obtained in writing.
      (2)   The local agency may elect to treat industrial wastes, discharged in excess of normal domestic concentrations, on a basis prescribed by written agreement and for an established surcharge to cover the added cost.
   (G)   The owner of any 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 local agency. 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.
   (H)   (1)   All measurements, tests, and analyses of the characteristics of waters and wastes to which references are made shall be determined in accordance with standard methods for examination of water and wastewater and guidelines establishing test procedure for the analysis of pollutants, Federal Regulation 40 C.F.R. part 136, published in the Federal Register on October 16, 1973, and shall be determined at the control manhole provided for in division (G) above, or upon suitable samples taken at said control manhole.
      (2)   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.
   (I)   No statement contained in this chapter shall be construed as preventing any special agreement between the local agency and any industrial concern whereby an industrial waste of unusual strength or character may be accepted, subject to payment therefor by the industrial concern, provided that such agreement shall not violate NPDES requirements and provided that user charges, surcharges, and industrial cost recovery payments as provided in this chapter are agreed to in the agreement.
