Definition Of Building Or House Sewer.

BUILDING OR HOUSE SEWER

That part of the horizontal pipe which begins outside of the wall of a building and connects the house drain with the main public sewer, septic tank or other disposal terminal.

Specific Requirements.

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

Independent system. Each house sewer and drainage system shall be independent of that of any other building except as provided below:

Where one (1) 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 (1) house sewer.

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 unless otherwise authorized by the Governing Body.

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 shall be made at the "Y" designated for that property. The only exception shall be where the designated "Y" is not located within three (3) 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 cleanout purposes.

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 municipality, supervise all house sewer connections and excavation for the purpose of installing or repairing the same.

Specifications.

Material. All house sewers shall be constructed of either vitrified clay sewer pipe meeting the A.S.T.M. Specifications for Extra Strength Clay Sewer Pipe (Designation C200) or extra heavy cast-iron soil pipe meeting A.S.T.M. Standard Specifications for Cast-Iron Soil Pipe and Fittings (Designation A-74).

Joints and connections.

Vitrified clay sewer pipe shall be fitted with factory-made resilient compression joints meeting the A.S.T.M. Specifications for Vitrified Clay Pipe Joints Having Resilient Properties (Designation C425).

(1)

Before joining the pipe in the trench, the bell and spigot surfaces shall be wiped free of dirt or other foreign matter. A lubricant as recommended by the pipe manufacturer shall be applied to the bell and spigot mating surfaces just before they are joined together.

(2)

The spigot end shall be positioned into the bell end of the pipe previously laid and then shoved home to compress the joint and to assure a tight fit between the 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.

Joints for extra heavy cast-iron soil 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 (1) inch deep. No paint, varnish or putty will be allowed in the joints until they have been tested.

Size of house sewer. No house sewer shall be less than four (4) inches in diameter. No building or house sewer for a commercial building or a multiple dwelling shall be less than six (6) inches in diameter.

Grades for house sewer. Unless otherwise authorized all house sewers shall have a grade of not less than one-eighth (1/8) inch per foot. A grade of one-fourth (¼) inch per foot shall be used wherever practical.

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 (4) 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 (2) feet above the pipe. Backfilling shall not be done until final inspection is made by the Sewer Inspector.

Use of old house sewers. 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 the public sewer.

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