(A) Prohibited water. It shall be unlawful for any owner, occupant or use of any premises to direct into or allow any stormwater, surface water, ground water, well water or water from industrial or commercial air conditioning systems to drain into the sanitary sewer system of the city. No rain spout, or other form of surface drainage and no foundation drainage or sump pump shall be connected or discharged into any sanitary sewer.
(B) Sump, pump and rigid pipe required.
(1) New subdivisions: all construction. A sump, pump and rigid pipe discharge connection to the outside shall be required for all construction in new subdivisions when it is determined necessary by the Public Works Supervisor or his or her designee to protect sanitary sewer infiltration. The Public Works Supervisor or his or her assigns shall conduct his or her analysis and make his or her determination of soil conditions on a subdivision basis. The sump, pump and rigid pipe discharge requirement will apply to all units constructed within a specific subdivision.
(2) Existing subdivisions: new construction. Any new construction in a subdivision platted prior to the effective date of this chapter shall be examined by the Public Works Supervisor or his or her assigns when the footing inspection is made. At that time the Public Works Supervisor or his or her assigns will determine, based upon excavated soils, whether the sump, pump and rigid connection are required. Should the building owner choose the option of installing a sump, pump and rigid connection where they are not required, they shall be installed in accordance with divisions (C)(1) and (C)(2) below.
(3) Existing subdivisions; existing construction. Any existing construction in a subdivision platted prior to the effective date of this chapter in which a sump and pump have been or will be installed, shall be required to install a rigid pipe connection discharge in accordance with division (C)(2) below. It shall be unlawful to maintain any connection with the sanitary sewer carrying roof water, ground water, surface water or any other natural precipitation after the effective date of this chapter.
(4) Exceptions. In certain locations where surface stormwater discharge would create a safety hazard during freezing weather, connection to the sanitary sewer may be maintained from November 1 to March 31. In no case, shall any connection to the sanitary sewer be maintained from April 1 to October 31. Exceptions will be granted by permit on a case by case basis as determined by the Public Works Supervisor or his or her designee. Any property owner receiving a permit shall pay a seasonal discharge monthly user fee established in the annual fee chart for use of the sanitary sewer system. The monthly fee shall be added to and collected with the regular monthly sewer bill of the property owner. Those sump pumps must be removed from the sanitary sewer before April 1 and a daily non-compliance fee set by the annual fee chart will be charged after April 1 for noncompliance.
(C) Sump, pump and rigid pipe: method of installation.
(1) The building shall have a drain tile placed around the inside or outside perimeter of the foundation connected to a sump pit. All baseboard seepage collection systems shall be discharged to the sump pit. The sump pit shall be located at least ten feet away from the inside sanitary floor drain.
(2) A discharge pipe shall be installed to the outside wall of the building with rigid pipe (plastic, copper, galvanized or black pipe) one inch inside diameter minimum. The discharge pipe must have a check valve within one foot of the floor grade and a union or other approved coupling for easy disconnection for repair or replacement. The discharge shall extend at least three feet outside of the foundation wall.
(3) Alternate methods of installation:
(a) The discharge pipe may be connected directly to the municipal underground storm sewer system provided the discharge is at a higher elevation than the normal flow level and that an approved backflow prevention device is installed;
(b) The discharge may be connected directly to the municipal curb and gutter system provided the pipe is placed under the sidewalk or boulevard and through the back of the curb and that an approved backflow prevention device is installed; and
(c) Any other discharge other than natural body fluids must be approved by the Public Works Supervisor or his or her assigns.
(D) Powers and authority of inspections. The Public Works Supervisor or his or her assigns and other duly authorized employees of the city bearing proper credentials and identification shall be permitted to enter all properties for the purpose of inspection, observation, measurement, sampling and testing pertinent to discharge to the community system in accordance with the provisions of this chapter upon one day’s notice to occupant.
