(a)   No unauthorized user shall uncover, make any connections with, or opening into, use, alter or disturb, any district sewer or appurtenance thereof without first submitting a written request with plans and drawings to the City Engineering Department.
   (b)   A sanitary sewer permit shall be required of all users for residential and commercial service, and for service to establishments producing industrial wastes.  In any case, the user or his or her agent shall make application on a form furnished by the District.  The street opening and applicable bonding application shall be supplemented by any plans, specifications or other information considered pertinent in the judgment of the City Engineering Department.  The tap-in fee, as established by the Utility Committee, shall be paid prior to the issuance of the street opening and applicable bonding permit.  No part of any lateral shall be covered until it has been inspected and approved by a designated City inspector. All materials used in the installation must be inspected and approved by the designated City inspector. Request for inspection must be submitted at least twenty-four hours in advance. Inspection will not be made on Saturdays, Sundays or holidays.
   (c)   The sewer, drain, lateral or connection thereto, at the designated City inspector's request, shall be subject to tests at the users expense in the presence of the designated City inspector. Testing shall be as referred to in subsection (n) hereof.
   (d)   All costs and expense incident to the installation, connection and testing of the lateral shall be borne by the user. The user shall indemnify the District for any loss or damage that may directly or indirectly be occasioned by the installation of the lateral.
   (e)   A separate and independent lateral shall be provided for every building, except that where one building stands at the rear of another on an interior lot and no private sewer is available or can be constructed to the rear building through an adjoining alley, court, yard or driveway, the lateral from the front building may be extended to the rear building, and such extension shall be considered a separate sewer connection and subject to the charges set forth in subsection (b) hereof, and the owner or occupant thereof shall be separately charged as a user. See schedule of connection requirements set forth below:
      (1)   EPA minimum slope requirements:
         4"   1.20%
         6"   0.62%
         8"   0.40%
         4"   -Single user connection
         6"   -High flow single user connection/multiple connections (two users for a single connection)
         8"   -Multiple connections (three or more users for a single connection)
      (2)   Possible multiple type connection situations:
         A.   Single lot with two residences;
         B.   Single lot with two or more trailers;
         C.   Single lot with one residence and one trailer;
         D.   Duplex units; and
         E.   Any combination where more than one user is connected to a single septic system.
   (f)   Old laterals may be used only when they are found and upon examination and testing by user in the presence of the designated City inspector to comply with all City requirements of these regulations.
   (g)   All District sewers and laterals within the District shall be in accordance with the following:
The design engineer should contact the local engineering department having jurisdiction prior to final material selection. The selection of materials should take into account the nature of the wastes to be transported, compatibility with adjacent and connecting materials and the cleaning methods which will be used.
   (h)   The size and slope of the lateral shall be subject to the approval of the designated City inspector but in no event shall the diameter be less than four inches.
   (i)   Whenever possible the lateral shall be brought to the building at an elevation below the basement floor. No lateral shall be laid parallel to or within three feet of any bearing wall, which might thereby be weakened. The depth shall be not less than forty-two inches to the top of the sewer pipe. The lateral 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, and there shall be accessible cleanouts properly placed at any change of direction of twenty-two and one-half degrees or more.
   (j)   All excavations required for the installation of laterals shall be open trench work unless otherwise approved by the designated City inspector. Pipe laying and back filling shall be performed in accordance with ASTM specifications, except that no backfill shall be placed until the work has been inspected. The inside of every sewer after it is laid must be left smooth and lean throughout its entire length, and be true to line and grade.
   (k)   The connection of the lateral into the District sewer shall be made at the service connection. If such service connection is not available, a suitable service connection will be provided by the District.
   (l)   The applicant for the lateral street opening and applicable bonding permit shall notify the City Engineers Office when the lateral is ready for connection to the District sewer. The connection shall be made by the applicant's contractor in the presence of designated City inspector.
   (m)   All excavations for lateral installation shall be adequately guarded with barricades and lights so as to protect the public from hazard. Streets, sidewalks, parkways and other public property disturbed in the course of the work shall be restored in a manner satisfactory to the District.
   (n)   Extension of District sewers shall be done only by the District when the need is established, or by the developer as required in the Subdivision Regulations.
