No unauthorized person shall uncover, make any connections with or openings into, use, alter or disturb any public sewer or appurtenance thereof without first obtaining a written permit from the Department.
Separate and independent service lines shall be provided for every applicant.
Old service lines may be used in connection with new applicants only when they are found, on examination and tested by the Department, to meet all requirements of this chapter. This examination may require exposing of the old line by excavation, which will be furnished and paid for by the applicant.
The service lines shall be cast-iron soil pipe (hub and spigot), ASTM Specification A74 (1979) or other suitable material approved by the Department. Joints shall be tight and waterproof. If installed in filled or unstable ground, the service line shall be of cast-iron soil pipe or approved nonmetallic material and shall be laid on a suitable concrete bed or cradle as approved by the Department.
The size and slope of the service line shall be subject to the approval of the Department, but in no event shall the diameter be less than four inches. The slope of such four-inch pipe shall not be less than 1/4 inch per foot. The slope of a six-inch pipe shall be not less than 1/8 inch per foot.
Whenever possible, the service line shall be brought to the structure at an elevation below the basement floor. No service line shall be laid parallel to and within three feet of any bearing wall, which might thereby be weakened. The depth shall be sufficient to afford protection from frost. The service line shall be laid at uniform grade and in straight alignment. Changes in direction shall be made only with properly curved pipe and fittings and with approval of the Department. Accessible cleanouts may be required by the Department in cases of sharp alignment changes or extremely long runs of pipe.
For applicants in which any service line is too low to permit gravity flow to the public sewer, sanitary sewage carried by such service line shall be lifted by approved mechanical means and discharged to the service line. The mechanical means shall be owned and maintained by the applicant, meet all applicable specifications and be approved by the Department.
The applicant shall not make connection of roof downspouts, foundation drains, cellar drains, areaway drains, building drains or other sources of surface runoff or groundwater to a service line or drain which in turn is connected directly or indirectly to a public sewer.
All excavations required for the installation of a service line shall be open trench work unless otherwise approved by the Department. Pipe-laying and backfill shall be performed in general accordance with the latest version of ASTM Specification C12, C13, the Manual of Practice No. 37, Design and Construction of Sanitary and Storm Sewers (ASCE), and in full accordance with local building codes, except that no backfill shall be placed until the work has been inspected and approved by the Department.
All joints and connections shall be made gastight and watertight in accordance with the applicable specifications.
Hub and spigot joints shall be furnished in patterns and sizes in accordance with ASTM A-74.
The connection of the service line into an existing public sewer shall be made at the property line, or, if a service line connection has not previously been provided, the service line will be connected to the existing public sewer. The cost of constructing and maintaining the service line from the public sewer to the property line will be at the district's expense. The cost of constructing and maintaining the service line from the property line to the structure will be at the applicant's expense. All costs and expense incidental to the installation, connection and maintenance of the service line, either new or existing, shall be borne by the applicant. The applicant shall indemnify the district and the town from any loss or damage that may, directly or indirectly, be occasioned by the installation of the service line. The method of connection of the service line to the public sewer will be dependent upon the type of sewer material used and in all cases shall be approved by the Department.
The applicant for the service line permit shall notify the Department when the service line is ready for inspection and connection to the public sewer. The connection shall be made under the supervision of the Department.
When trenches are opened for the laying of service line pipes, such trenches shall be inspected by the Department before the trenches are filled, and the applicant performing such work shall notify the Department when the laying of service line is completed.
"As-built" drawings shall be provided to the Department by the applicant within 30 days of completion of the project.
Prior to any excavation for service line installation, a permit for such excavation shall be obtained from the Department.
Service line traps shall be located within the property line, inside the structure wherever practicable, on the service line within two feet of exterior wall of the structure and on the sewer side of all connections except those approved by the Department. Trap cleanouts in structures are required to be level with the finished basement or cellar floor.
Every sanitary service line equipped with a trap, sewage sump, ejector, receiving tank, oil separator or similar equipment shall be provided with a fresh-air inlet pipe connected to the service line immediately upstream from and within four feet of such trap or equipment. The fresh-air inlet pipe shall be extended to the outer air and shall be terminated in an open end at least six inches above grade. The open end shall be protected by a perforated metal plate permanently fixed in the mouth of the inlet. A return bend with its protected open end at least six inches above grade shall be installed within the property line in an approved location, when the trap is located outside the structure. The size of the fresh-air inlet pipe shall be at least 1/2 of the diameter of the service line at the point of connection, but not less than three inches.
In areas where sanitary sewers drain to a wastewater pumping station, an approved backwater valve shall be installed, at the applicant's expense, in all structures subject to flooding during a failure of the pumping facilities. The location of said backwater valve shall be as indicated on the drawing for a typical applicant's connection from the Department.
Whenever any street or public grounds shall be opened for the purpose of making a connection with the mains or for the laying of sewer lines or fixtures, public safety and convenience shall be duly regarded, and the street or public place shall be restored to its original condition as soon as possible, and all work must conform to the safety requirements as set forth by the State of New York and OSHA. The applicant must obtain, from the appropriate departments, the required permits and display the same in the Town of Schodack.
