   921.01 PURPOSE AND POLICY.
   (a)   This chapter sets forth uniform requirements for discharges into the POTW Authority wastewater collection and treatment systems, and enables the "Authority" to protect public health in conformity with all applicable State and Federal laws relating thereto.
 
   (b)   The objectives of this chapter are:
      (1)   To prevent the introduction of pollutants into the Authority wastewater system which will interfere with the normal operation of the system or contaminate the resulting sludge;
      (2)   To prevent the introduction of pollutants into the Authority wastewater 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;
      (3)   To improve the opportunity to recycle and reclaim wastewater and sludge from the system.
 
   (c)   This chapter provides for the regulation of discharges into the Authority POTW through the enforcement of administrative regulations. This chapter does not provide for the recovery of operations maintenance or replacement costs of the POTW, which are the subject of separate enactments.

   (u)   Construction of Public Sewers and Building Sewers.
      (1)   Pipe specifications. Unless approved by the Engineer, the following materials shall be used in constructing public sewers and building sewers:
         A.   Clay-Vitrified Clay extra strength C-700 having a premium seal joint conforming to C-425.
         B.   ABS-Acrylonitrile Butadiene Styrene ASTM D 2680, having a premium seal joint constructed of chemically welded solid ABS couplers on the exterior of the joint.
         C.   PVC-Polyvinyl chloride plastic thick wall ASTM 3034 having an SDR of 35 or less and having a premium seal joint either chemically welded or having an elastomeric gasket joint, PVC pipe other than listed above shall be permitted only when approved by the Engineer. The approval will be subject to depth of installation, trench width, soil conditions and locations of the pipe. PVC pipe shall be acceptable for building sewers and public sewers.
      (2)   Installation. The requirements for bedding, haunching, initial backfilling and backfilling shall be in accordance with standard detail drawings on file with the City Engineer.
         A.   Bedding. A minimum layer of six inch bedding consisting of #57 granular bedding material shall be provided upon a stable undisturbed subgrade. If an unstable subgrade is encountered, the Engineer shall determine the method of building required subgrade support.
         B.   Haunching. After the pipe has been placed on the approved bedding material #57 granular material shall be placed around the sides of the pipe from the undisturbed trench wall to the pipe. Under no circumstances shall the maximum allowable trench width for the type, size and depth of pipe be exceeded. Unless otherwise approved or ordered, the maximum allowable trench widths measured at the top of the pipe shall be twenty-seven inches for six and eight inch diameter pipe, thirty inches for ten inches diameter pipe, thirty-three inches for twelve inch diameter pipe.
         C.   Initial backfill. After the haunching of the pipe has been completed, the pipe shall be covered with #57 granular material to the plane, six inches above the top of the pipe.
         D.   Backfill. Upon completion of the initial backfill, the best excavated material shall be used for backfilling the trench. Trash, boulders, frozen soil, etc., shall not be used as backfill material. If the pipe is laid under a pavement or berm area, the pipe shall be backfilled with approved granular material, a minimum of six feet beyond the edge of the berm or edge of pavement in absence of a berm.

No construction of sewers shall be allowed on legal holidays, Saturdays, Sundays or after 4:30 p.m. unless written permission is obtained from the Service Director. The Service Director may require the payment by the contractor or inspection costs for work performed on days and at times listed in the written permission.
   (x)   No sewer pipes for a water closet or any other connection shall be allowed inside any house or building unless proper means are provided for the ventilation of such pipe or sewer so as to effectually prevent sewer gas from entering the house or building.
 
   (y)   It shall be a minor misdemeanor for the owner of any property abutting upon any public sewer, or which is drained or may be drained by any public sewer, to construct, cause or suffer to be constructed from his property or any part thereof any drain or sewer to connect with any public sewer unless there is provided for and attached to the drain or sewer a good and sufficient trap.
   (z)   The Service Director shall cause to be taken up or removed any drain or sewer constructed in violation of subsection (y) hereof so far as the same is within the limits of any public property, thereby disconnecting such sewer or drain from any public sewer, unless the owner or person benefitted by the drain or sewer provides a trap therefor.
