935.01 GENERAL PROVISIONS; PURPOSE AND POLICY.

   This chapter sets forth uniform requirements for discharges into the POTW Authority Sewage Collection and Treatment Systems, and enables the POTW Authority to protect public health in conformity with all applicable state and federal laws relating thereto.

   The objectives of this chapter are:

   (a)   To prevent the introduction of pollutants into the municipal sewage system which will interfere with the normal operation of the system or contaminate the resulting sludge;

   (b)   To prevent the introduction of pollutants into the municipal sewage system which do not receive adequate treatment in the POTW, and which will pass through the system into receiving waters or the atmosphere or otherwise be incompatible with the system;

   (c)   To improve the opportunity to recycle and reclaim sewage and sludge from the system.

   This chapter provides for the regulation of discharges into the POTW through the enforcement of administrative regulations. This chapter does not provide for the recovery of operations, maintenance or replacement costs of the POTW or the costs associated with the construction of collection and treatment systems used by industrial dischargers, in proportion to their use of the POTW, which are the subject of separate enactments.

   The procedures, technical information and specific requirements necessary to accomplish these objectives are detailed in the City of Mansfield Pretreatment Program, which is administered through the POTW Authority as a part of the Public Works Department.

House sewers shall be not less than six inches in diameter. If installed in filled or unstable ground, the building sewer shall be of cast iron soil pipe, except the vitrified clay sewer pipe or Polyvinyl Chloride (PVC) pipe material may be used if laid on a suitable concrete bed or cradle as approved by the Public Works Director.

   (i)    The size and slope of the building sewer shall be subject to the approval of the Public Works Director, but in no event shall the diameter be less than six inches. The slope of such six-inch pipe shall not be less than 1.04% or one-eighth inch per foot.

   (j)    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 building sewer shall be laid at uniform grade and in straight alignment insofar as possible. Changes in direction shall be made only with properly curved pipe and fittings.

   (k)    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 approved artificial means and discharged to the building sewer.

   (l)    All excavations required for the installation of a building sewer shall be open trench work unless otherwise approved by the Public Works Director. Pipe laying and backfill shall be performed in accordance with ASTM Designation (C-12) except that no backfill shall

be placed until the work has been inspected.

   If the construction is backfilled or otherwise covered before such inspection, the Public Works Director may require the fill or cover to be removed at the expense of the permittee or person making such tap. Such expense if not otherwise paid, shall be an obligation under the bond provided for in Section 935.07.

   (m)    Pipe shall be laid on six inches of crushed stone bedding material conforming under ASTM #67 crushed aggregate. It shall be a blend of angular materials in the general size range of one-fourth inch to three-fourths inch. It shall conform to the following sieve analysis: 10% passing one inch; 90-100% passing three-fourths inch; 20-55% passing three-eighths inch; 0-10% passing #4; 0-5% passing #8. Measurement shall be by weight.

   After the bedding material is placed in the bottom of the trench, the pipe shall be laid in the bedding material with care being taken to insure that the bottom of the pipe is resting on the bedding material for its full length. The pipe shall then be adjusted to the proper elevation by adding or removing bedding material as required.

   After the piping installation is approved by the Public Works Director, it shall be backfilled to a depth of at least six inches above the top of the pipe with granular material conforming to that specified for bedding material. This initial backfill shall be thoroughly tamped to the satisfaction of the Public Works Director with precaution taken so that no misalignment and no change in grade will occur during the backfilling operation.

   The balance of the trench located outside the pavement limits shall be backfilled with the excavated materials free of large stones or lumps. All excavations within the limits of street pavement, parking areas or public drives shall be backfilled with gravel backfill compacted in place. Gravel backfill shall meet with approval of the Public Works Director prior to its installation. All excavations shall be adequately guarded with barricades and lights so as to protect the public from hazard.

   (n)    The connection of the building sewer into the public sewer shall be made at a wye or tee fitting, if such fitting is available at a suitable location. If the public sewer is fifteen inches in diameter or less, and no properly located wye or tee fitting is available, the owner shall at his own expense install a wye or tee fitting in the public sewer at the location specified by the Public Works Director. This shall be done by neatly sawing pipe and connecting with stainless steel "no-hub" connectors. Where the public sewer is greater than fifteen inches in diameter, and a wye or tee fitting is not available, connection into the public sewer shall be made by using a saddle completely encased in concrete and made watertight. Long radius forty-five degree shall be used, as required, at the wye or tee fittings.

   (r)    Each person who makes openings, taps or connections with or constructs sewers or drains upon or over public streets or property, shall keep in repair and good order the whole of the work executed by him, until the same is accepted by the Public Works Director or his authorized representative, which acceptance shall be given in writing, and if deemed necessary by the Public Works Director may be deferred until the expiration of one year after the completion of the work.

   (s)    In case it is necessary to connect a drain or sewer pipe with a public sewer or drainage facility when no junction is left in the same, the new connection with the public sewer or drainage facility shall be made only when a representative of the City, designated by the Public Works Director, is present to see the whole of the work performed.

   (t)    The owner shall maintain and repair private sewers lying within the right of way limits of dedicated public streets and alleys.

   (u)    The Public Works Director is hereby authorized to make and enforce such regulations as may be necessary or proper in respect to or to provide for:
