(A) Building sewers shall be constructed as part of the improvement to the property line of the premises served.
(B) The building sewer shall be connected into the public sewer at the curb or property line, if a service connection sewer is available at this location. Where no curb or property line located service connection sewer is available, the owner of the building sewer shall extend the building sewer to the public sewer and connect to the nearest wye or tee available on the public sewer. If no wye or tee exists on the public sewer within the immediate vicinity of the frontage of the lot or tract of land that the building sewer is to serve, the owner of the building sewer shall have a wye or tee installed on the public sewer, in accordance with requirements hereinafter set forth.
(C) 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 straight alignment. Changes in direction shall be made only with properly curved pipe and fittings.
(D) Whenever the public sewer is deep enough to serve basements, all sanitary fixtures should be connected to the public sewer by gravity. This connection should include all laundry facilities and the basement floor drain. Backwater traps are recommended for the basement floor drain when connections are made in this manner.
(E) In those instances where the public sewer is not of sufficient depth to serve the basement fixtures, the owner will be permitted to install a high level connection and pump laundry waste and the waste from the basement floor drain to the sanitary sewer by means of a sump pump.
(F) The removal of an existing sump pump shall be at the option of the owner. However, if it is to remain in service to pump sanitary sewage into the building sewer (including laundry waste and the basement floor drain), all foundation drains or other groundwater or storm water connections thereto shall be permanently disconnected therefrom and handled in some other manner. If it is to remain in place to pump ground water or storm water, all sanitary connections shall be broken and sealed and the discharge from the sump pump shall be piped to a proper storm drain, natural outlet, or drainage field. An abandoned drainage field or drainage well may be used for disposal of groundwater or storm water.
(G) Connections to existing public sewers where wyes or tees are not available shall be made by one of the following methods:
(1) A wye or tee saddle shall be installed according to details shown on District Standard Detail, copy of which is available at the district office.
(2) A tee saddle shall be installed, using a Wheeler-Pilot Hole Cutter (tapping machine) or equivalent machine and a saddle expressly made to fit into the hole formed by the machine. The saddle shall be sealed to the sewer with an epoxy material formulated for bonding to the sewer material and the saddle. The saddle material may be a corrosion resistant material or a polyester. The strength of the installed and bonded saddle shall exceed the strength of a factory installed tee.
(3) A standard wye or tee pipe section shall be installed, by cutting out the sewer pipe, maintaining squared ends, inserting the standard wye or tee pipe section, and sealing each joint with a ribber collar adapter. Each joint space between the existing pipe and the inserted section shall not exceed one inch. The collar adapter shall be compressed to the pipe by means of two stainless steel screw-takeup bands.
(H) The details and construction of all connections shall be inspected and approved by the Mayor or his authorized representative and by the Plumbing Inspector.
