The drainage and plumbing system of each new building and of new work installed in an existing building shall be separate from and independent of that of any other building, except as provided below, and every building shall have an independent connection with a public or private sewer when available.
When one building stands in the rear of another building on an interior lot and no private sewer is available or can be constructed to the rear building through an adjoining alley, courtyard or driveway, the house sewer from the front building may be extended to the rear building, and the whole will be considered as one house sewer.
Old drains may be used in connection with new buildings or new plumbing only when they are found, on examination and test, to conform in all respects to the requirements governing new drains, as prescribed in this code. If the old work is found defective, the proper administrative authority shall notify the owner to make the necessary changes to conform with this code.
Every new building must have its sewer connection directly in front of the building unless permission is otherwise granted by the Building Inspector.
After an owner has been notified that the lateral sewer line available to his building has been completed and is ready for use, he may apply for a permit from the county and village to connect thereto. After such notice has been given, permits for the cleaning of existing cesspools will be granted. When a building is connected to the county sewer system, all cesspools on said property shall be cleaned out, disinfected and properly and completely backfilled with clean fill.
When a septic tank and/or cesspool is being discontinued, the house sewer may be connected at the inlet of the septic tank and/or cesspool.
Where a house sewer is connected at the point of entry to a septic tank and/or cesspool, connection must be made by bridging with one length of extra-heavy ductile iron pipe. Pipe must be properly supported at wall with open space above same to prevent damage to joints in the event that the septic tank and/or cesspool settles.
[Amended 8-12-1974 by L.L. No. 7-1974]
The sewer connection to a building shall comply with all the regulations of the County of Nassau, Department of Public Works, Division of Sanitation and Water Supply.
No pipe shall be laid in any trench unless the sewer connection to the building and the connection to the sewer at the curb are exposed. All pipe shall be laid with a uniform fall and in as direct and straight a line as possible from two feet outside the outer face of the building wall or point where existing cast-iron pipe extends through the wall to the existing connection to the sewer at the curb. The minimum fall per foot of pipe laid shall be 1/8 inch per foot. Sewer piping shall be supported throughout its entire length.
Tunneling may be done in yards, courts or driveways of any building site, provided that cast-iron pipe is used. However, the diameter of the tunnel may not be over twice the diameter of the pipe, and it shall be of such length as will permit inspection of all joints outside the tunnel. All tunnels shall be backfilled by the use of water.
[Amended 8-12-1974 by L.L. No. 7-1974]
Adequate precaution shall be taken to ensure proper compaction of backfill around pipe without damage to piping. Trenches shall be backfilled in thin layers to 12 inches above the top of the pipe with clean earth, which shall not contain stones, boulders, cinderfill or other materials which will damage or break the pipe or cause corrosive action. Mechanical devices may then be used to finish backfilling to grade. All trenches shall be compacted with water, using the jetting method.
The sewer connection to a building shall have a horizontal or lateral separation of at least seven feet or a vertical separation of at least two feet and shall be located below the water service. In the event that any of the above minimum separations are not possible, permission must be obtained from the Building Inspector to vary the above requirements, and his decision as to location and type of pipe to be used shall be followed.
The plumber making the sewer connection to a building shall be responsible for any damage to village property, including but not limited to sidewalks, aprons, trees, grass area and curbs. He shall take all precautions necessary to protect village property.
Any open trench or other obstruction in, on or abutting the sidewalk, street or other village property shall be surrounded by suitable barriers or guards for protection of persons using the streets or property in the daytime and, in addition thereto, by lights or flares from twilight continuously until daylight. Such barriers and lights shall conform, in kind and number, to the requirements of the Building Inspector.
Immediately upon the approved inspection of the sewer connection to a building, the plumber shall see that all trench settlement is properly filled to the grade of the original ground.
[Added 8-12-1974 by L.L. No. 7-1974]
All excavations for a sewer connection exceeding the depth of five feet shall be properly shored with plywood or sheathing material so as not to cause wholesale cave-in of the trench and surrounding area.
The Building Inspector shall be notified 24 hours in advance of the starting of work under any permit issued hereunder and shall be further notified before 10:00 a.m. of the day an inspection is required. The following inspections are required under this article and may be performed simultaneously.
First inspection. The first inspection shall be made when the pipe is laid and joints are made but before any backfill is placed on the pipe.
Second inspection. The second inspection shall be made when the cesspool or cesspools are cleaned but prior to backfilling.
Third inspection. The third inspection shall be the final inspection and shall be made when the sewer connections to a building are complete.
