SEWER CONSTRUCTION AND STANDARDS

CHAPTER 22.

22-1. Definition of Building Sewer. Building Sewer: That part of the lowest horizontal pipe which begins 5 feet outside of the wall of a building and connects the "House Drain" with the main public sewer or other disposal terminal.

22-2. Specific Requirements.

1. Rain Water Leaders: Roof leaders, surface drains, or ground water drains shall not be connected to the sanitary sewer.

2. Independent System: Each building 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 or an interior lot, the building sewer from the front building may be extended to the rear building and the whole considered as one house sewer.

3. Use of Public Sewer Required: 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 as provided by the sanitary sewer rules and regulation and/or rates ordinances.

4. Connection to the Main Public Sewer : Before any connection is made to a public sewer, an approved permit for such connection must be obtained from the governing body or its designated representative. Each connection to the main sewer shall be made to the fitting designated for that property. If a fitting in the main sewer is not available for the designated property the connection shall then be made under the direct supervision of the Sewer Inspector.

A "Y", "T" or "Cleanout" fitting shall be installed near the building foundation to provide for cleanout purposes.

22-3. Supervision. Sewer Inspector: The 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 City, supervise all building sewer connections and excavations for the purpose of installing or repairing the same.

22-4. Specifications.

1. Material: All building sewers shall be constructed of either Vitrified Clay Sewer Pipe meeting A.S.T.M. Specifications for Clay Sewer Pipe (Designation C-700), Extra Heavy Cast Iron Soil Pipe meeting A.S.T.M. Specifications for Cast Iron Soil Pipe and Fittings (Designation A-74), of PVC gravity sewer pipe, meeting A.S.T.M. Specification D 3034 "Type PSM Poly (PVC) Sewer Pipe and Fittings."

2. Pipe, Joints and Connections:

a. Vitrified clay pipe, joints, and connections shall be installed according to the manufacturers' recommendations, and shall conform to:

1) Pipe - A.S.T.M. C-700, "Clay Sewer Pipe".

2) Joints - A.S.T.M. C-425, "Compression Joints for Vitrified Clay Bell and Spigot Pipe".

3) Couplings - A.S.T.M. C-594, "Compression Couplings for Vitrified Clay Plain - End Pipe".

b. Extra Heavy Cast Iron Soil Pipe and Joints shall be installed according to the manufacturers' recommendations and shall conform to:

1) Pipe - A.S.T.M. - A-74, "Cast Iron Soil Pipe and Fittings".

2) Joints - A.S.T.M. C-564, "Rubber Gaskets for Cast Iron Soil Pipe and Fittings".

c. Polyvinyl Chloride (PVC) and joints shall be installed according to the manufacturers' recommendations and shall conform to:

1) Pipe - A.S.T.M. D-3034, "Type P.S.M. Poly (PVC) Sewer Pipe and Fittings".

Minimum wall thickness:

4" - 0.125"

6" - 0.180"

8" - 0.240"

10" - 0.300"

2) Joints - A.S.T.M. D-1869, A.S.T.M. D-3212, "Flexible Elastomeric Seals".

3. Size of building sewer: No building sewer shall be less than four inches in diameter. No building sewer for a commercial building or a multiple dwelling shall be less than six inches in diameter.

4. Grades for building sewers: Unless otherwise authorized all building sewers shall have a grade of not less than one-eighth (1/8) inch per foot. A grade of one-fourth inch per foot shall be used wherever practical.

5. Trenching and Backfilling: 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, course sand or similar material so as to provide a firm foundation and uniform support for the building 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. Use of Old Building Sewers: Old building 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 building sewer that is also connected to the public sewer.

22-5. Inspection. Each and every part of the building sewer shall be inspected and approved by the Sewer Inspector before being concealed or backfilled.

22-6. Penalties. Any person violating any of the provision of this Chapter shall become liable for any expense, loss or damage by reason of such violation as provided by the Rules & Regulation and/or Rates ordinances.
