(A) A building or house sewer is that part of the horizontal pipe which begins outside of the wall of the building and connects the house drain with the main public sewer, septic tank or other disposal terminal.
(B) The following specific requirements are hereby established.
(1) Rain water leaders, including roof leaders, surface drains or ground water drains shall not be connected to the sanitary sewer except upon approval by the Sewer Inspector.
(2) Each house sewer and drainage system shall be independent of that of any other building, except as provided below: where one building stands in the rear of another building located on an interior lot, the house sewer from the front building may be extended to the rear building and the whole considered as one house sewer.
(3) Where a public sewer is accessible in a street or alley to a building or premises abutting thereon the liquid wastes from any plumbing system in said building shall discharge into the public sewer unless otherwise authorized by the governing body.
(4) Before any connection is made to the public sewer, an approved permit for such connection must be obtained from the governing body or its designated representative. Each connection shall be made at the “Y” designated for that property. The only exception shall be where the designator “Y” is not located within three feet of the point of measurement furnished by the local governing body. Any connection not made at the designated “Y” in the main sewer shall be made under the direct supervision of the Sewer Inspector. A “Y” or “T” fitting shall be installed near the building foundation to provide for cleaning purposes.
(C) A Sewer Inspector shall be appointed pursuant to the laws of the city and state and shall, under the direction of the governing elective officers of the municipality, supervise all house sewer connections and excavations for the purpose of installing or repairing the same.
(D) The following specifications shall be followed.
(1) All house sewers shall be constructed of either vitrified clay sewer pipe, meeting the A.S.T.M. Standard Specifications for clay sewer pipe (designation C-13 or C-261) or heavy cast iron soil pipe meeting A.S.T.M. Standard Specifications for cast iron soil pipe and fittings (designation A-74).
(2) The following joints and connections are specified.
(a) Vitrified clay sewer pipe shall be fitted with factory made resilient compression joints meeting with A.S.T.M. Specifications for vitrified clay joints having resilient properties (designation C-425 or slip seal joints).
(b) Before joining the pipe in the trench, the bell and spigot surfaces shall be wiped free of dirt or other foreign matter. A lubricant or sealer as recommended by the pipe manufacturers shall be applied to the bell and spigot mating surfaces just before they are joined together.
(c) The tops or one side of the spigot end shall be positioned into the bell end of the pipe previously laid and shall then be shoved home to compress the joint and to assure a tight fit between the surfaces interfaces. Special compression adaptors or field unions shall be used where connections are made to street sewers, building drains, cut pipe or to pipe lines already in place.
(d) Joints for extra heavy cast iron pipe shall be made by inserting a roll of hemp or jute and thoroughly caulking it into place and then following with pure molten lead well caulked, not less than one inch deep. No paint, varnish or putty will be allowed in the joints until they have been tested.
(3) No house sewer shall be less than four inches in diameter. No building or house sewer for a commercial building or a multiple dwelling shall be less than six inches in diameter.
(4) Unless otherwise authorized all house sewers shall have a grade of not less than one-eighth inch per foot. A grade of one-fourth inch per foot shall be used wherever practical.
(5) All excavations shall be open trench work unless otherwise authorized by the Sewer Inspector. The foundation in the trench shall be formed to prevent any subsequent settlement of the pipes. If the foundation is good, firm, earth, the earth shall be pared or molded to give a full support to the lower quadrant of each pipe. Bell holes shall be dug. Where the floor of the trench is of hard or rocky material, the trench shall be excavated to four inches below grade and brought back to the proper grade with fine gravel, coarse sand or similar material so as to provide a firm foundation and uniform support for the house sewer line. Backfilling shall be placed in layers and solidly tamped or packed up to two feet above the pipe. Backfilling shall not be done until final inspection is made by the Sewer Inspector.
(6) All old house sewers or portions thereof may be approved for use by the Sewer Inspector. The Sewer Inspector may request that the old sewer be excavated for the purpose of facilitating inspection. No old cesspool or septic tank shall be connected to any portion of a house sewer that is also connected to a public sewer, except when approved by the Sewer Inspector.
(E) Each and every part of the house sewer shall be inspected and approved by the Sewer Inspector before being concealed or backfilled.
(F) The inspection and connection fees shall be as follows.
(1) The connection fee for strictly non-sanitary sewers shall be $50.
(2) The connection fee shall be $750 for strictly sanitary sewers.
(3) No person other than city employees shall be permitted to tap sewers.
