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.
A.
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.
B.
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.
C.
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.
D.
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.
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.
A.
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.
B.
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.
C.
"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.
