There shall be three classes of building sewer permits: for residential, for commercial service and for service to establishments producing industrial wastes. In either case, the owner or his agent shall make application on a special form approved by the Town Board and furnished by the Commissioner. The permit application shall be supplemented by any plans, specifications, or other information considered pertinent in the judgment of the Commissioner and/or Town. Permit fees shall be as specified by the Town Board according to the adopted rate schedule, which shall be updated periodically, and shall be paid to the Town at the time an application is filed.
A separate and independent building sewer shall be provided for every building, except that where one building stands at the rear of another on an interior lot and no private sewer is available or can be constructed to the rear building through an adjoining alley, court, yard or driveway, the building sewer from the front building may be extended to the rear building and the whole considered as one building sewer. In such cases, approval shall be obtained from the Commissioner prior to installation of the building sewer.
Old building sewers may be used in connection with new buildings only when they are found, on examination and test by the Commissioner, 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 owner.
A.
Sanitary sewer gravity pipe, unless pressure-rated pipe required per IAC, shall be polyvinyl chloride ( PVC) in accordance with ASTM D 3034-89 with a minimum wall thickness designation of SDR 35 and installed per ASTM D 2321-89 specification. PVC pipe used shall be grooved bell, spigot end, and gasketed. The pipe shall be made of PVC plastic having a cell classification of 124548.
[Amended 3-20-2019 by L.L. No. 1-2019; 12-15-2021 by L.L. No. 8-2021]
B.
The size and slope of the building sewer shall be subject to the approval of the Commissioner, but in no event shall the diameter be less than six inches. The slope of a six-inch pipe shall not be less than 1/8 inch per foot.
[Amended 3-20-2019 by L.L. No. 1-2019]
C.
Whenever possible, the building sewer shall be brought to the building at an elevation below the basement floor. No building sewer 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 building sewer shall be laid at uniform grade and in straight alignment. Changes in direction shall be made only with properly curved pipe and fittings.
D.
In all buildings in which any building drain is too low to permit gravity flow to the public sewer, sanitary sewage carried by such drain shall be lifted by approved mechanical means and discharged to the building sewer.
No person shall make connection of roof downspouts, foundation drains, cellar drains, areaway drains or other sources of surface runoff or groundwater to a building sewer or drain which in turn is connected directly or indirectly to a public sanitary sewer.
[Amended 3-20-2019 by L.L. No. 1-2019]
All excavations required for the installation of a building sewer shall be open trench work unless otherwise approved by the Commissioner. Pipe laying and backfill shall be performed in full accordance with the local building codes, except that no backfill shall be placed until the work has been inspected and approved by the Commissioner. All pipes laid under paved portion of Town highways shall be directly bored unless otherwise approved by the Commissioner due to local soil conditions or conflicts with other buried utilities.
[Amended 3-20-2019 by L.L. No. 1-2019; at time of adoption of Code (see Ch. 1, General Provisions, Art. I)]
A.
The applicant for the building sewer permit shall notify the Commissioner when the building sewer is ready for inspection and connection to the public sewer lateral. The connection shall be made under the supervision of the Commissioner or his representative.
B.
When trenches are opened for the laying of building sewer pipes, such trenches shall be inspected by the Commissioner before the trenches are filled, and the plumber performing such work shall notify the Commissioner when the laying of building sewer is completed.
Prior to any excavation for building sewer installation, a permit for such excavation shall be obtained from the Town Commissioner of Public Works when excavation will take place in or under a Town-owned street, highway or other public place. Work shall be performed in conformance with that Town law or ordinance which prescribes procedures for such excavations.
Building traps shall be located within the property line, inside the building wherever practicable, on the building drain line within two feet of the exterior wall of the structure and on the sewer side of all connections except those provided to receive the discharge from a sewer lift, oil separator, blowoff and condensing tank or leader. Trap cleanouts in buildings are required to be at least one inch above the level of the finished basement or cellar floor.[1]
[Added at time of adoption of Code (see Ch. 1, General Provisions, Art. I)]
A.
Grinder pumps will be installed only when a gravity sewer cannot be utilized. All grinder pump installations will be approved by the Commissioner of Public Works or his/her representative. Grinder pumps installed on a lateral remain the property of the owner; the Town of East Greenbush assumes no maintenance responsibility for a grinder pump or pump chamber.
B.
The grinder pump unit can be installed inside or outside of the building. The model of the pump selected will be determined by the location of the installation, either inside or outside of the building.
C.
The grinder pump control panel must include an alarm circuit containing an audible horn, warning light and a reset button.
D.
All electrical wiring for pump installation shall conform to applicable electrical code requirements.
E.
Discharge piping shall be in accordance with the pump manufacturer's recommendation. Pipe shall be PVC SDR 21 rubber gasket bell and spigot joint pipe for size 1 1/2 inch or larger. For 1 1/4 inch pipe, PVC Schedule 80 or PVC SDR 21 can be used with PVC compression couplings. Where 1 1/4 inch PVC bends are necessary, socket-type Schedule 40 or Schedule 80 bends are to be used. Bends are to be glued to the barrel of pipe outside of the trench. Ninety-degree bends are not acceptable. Two 45° bends with two-foot nipple are to be used to make a 90° turn.
F.
Connection to the existing manhole shall be a core and seal boot type.
G.
Discharge piping shall be installed with a minimum of 48 inches of cover to prevent freezing. Suitable bedding and backfill material shall be placed to a minimum of 12 inches above the crown of the pipe.
H.
A No. 12 gauge copper insulated tracer wire, continuous, shall be buried with pipe and terminated above-grade at the pump control panel for locating pipe in the future.
I.
Burial tape stating "caution buried sewer below" shall be placed 18 inches below finish grade in the pipe trench line centered over the pipe.
J.
A hydrostatic (water) pressure test must be performed on discharge piping prior to pump connection. The pipe shall be pressurized to 90 psi and witnessed by a Sewer Department Inspector.
K.
All grinder pump installations shall include a cast-iron double-hand whole trap and fresh air inlet. Exterior pump installations will require an outside cast iron cleanout to be installed on building drain.
L.
Prior to final approval of the grinder pump installation, the following documentation must be submitted to the Water and Sewer billing office:
(1)
For existing structures, a copy of the third-party inspection for all electrical work associated with the pump installation. A copy of the third-party inspection is not required for new construction.
(2)
Documentation by a representative of the pump manufacturer that the grinder pump was installed in accordance with the manufacturer’s requirements and that the system was startup tested with verification of proper alarm activation.

The location of said backwater valve shall be as indicated on the drawing for a typical house connection or as directed by the Town.
All excavations for building sewer installations shall be adequately guarded with barricades and lights so as to protect the public from hazard. Streets, sidewalks, parkways and other public property disturbed in the course of the work shall be restored in a manner satisfactory to the Town.
