All gravity sewer mains shall be PVC gravity sewer pipe conforming to standards set forth by the Borough's Engineering Consultant(s), DEP, Army Corps of Engineers or EPA. The minimum depth of a gravity sewer main shall be four feet measured from finished grade to the top of the pipe.
A. 
All building sewers and underground pipes leading to and inclusive of the building sewer shall be:
(1) 
Cast iron soil pipe and fittings, extra heavy and service weights conforming to ASTM A74; or
(2) 
ABS sewer pipe, schedule 40 pipe and fittings conforming to ASTM D2661; or
(3) 
PVC sewer pipe, schedule 40 pipe, and fittings conforming to ATSM D2665.
B. 
All building sewers shall be four inches in diameter or greater. The Borough may require pipe that is larger if the building contains multiple EDUs or uses water or discharges flow that exceeds the capacity of pipe that is only four inches in diameter. The slope or grade of a building sewer shall be no less than 1/4 inch per foot of length sloping downward in the direction that the waste material is to flow. The minimum depth of a building sewer shall be 24 inches measured from finished grade to the top of the pipe.
All fittings shall be of the same material as the pipe used in the construction. Any fitting or connection which has an enlargement, chamber, or recess with a ledge, shoulder or reduction of pipe area that offers an obstructed flow through the pipe is prohibited. Connections between different types of pipe materials are prohibited. Connections between different types of pipe materials shall be made by adapter fittings or by means of an acceptable prefabricated sealing ring or sleeve specifically approved by the plumbing inspector or Engineer. Concrete mortar joints shall not be permitted.
Manholes and sewer mains shall be specified by the Engineer, a designated and approved engineering firm as specified by the Borough, or appropriate state or federal agency as deemed required by the Borough.
Any sewer construction that will require excavation on a street or trafficway shall be restored to original condition and shall have pipe bedding installed consisting of predominantly sand and gravel, Penn DOT type No. 1B crushed stone, or other material approved by the Engineer. The surface shall be restored and maintained for a period of 60 days to assure proper restoration.
Select backfill shall consist of Penn DOT Type 2B modified or other material approved by the Engineer. No other soils shall be used.
All backfill shall be compacted as follows:
A. 
Bedding and select backfill shall be compacted in lifts not exceeding four inches using approved compaction equipment to 95% of maximum density.
B. 
Compaction shall be required if construction is to be at a point for connection where the connection of a building sewer is to be at a lateral so as to prevent the trafficway surface in area of the lateral to be damaged.
Each building sewer shall be equipped with a test tee and riser as needed, located at a point no greater than 10 feet from the point where the building sewer enters the service lateral.
The building sewer must be provided with double horizontal trap, known as an intercepting trap, no less than four inches inside diameter, which shall be provided with vent and cleanout openings, each of the latter brought to a height of at least the finished grade level and there provided with flush type or mushroom type cap vents. Lines and pipes from the trap to finished grade shall be of the same size and of the same material as the trap, or as specified for the main soil line.
Where determined necessary, the Borough may require grease traps to intercept greasy wastes prior to such wastes entering the Borough's main lines or laterals.
All sewer installations that require trench depths exceeding four feet shall be started only when proper shoring devices are on the property prior to construction commencing, and that the shoring devices shall be used when depths aforementioned are reached. OSHA standards shall be applied in all construction activities and digging.
No person shall make any connection of roof downspouts, exterior foundation drains, areaway drains, or other sources of surface runoff or ground water to a building drain which, in turn, is connected directly or indirectly to a public sanitary sewer.
Where a trench is in excess of 12 feet in depth, the pipe to be used in construction shall be Schedule 80 PVC or equivalent.
Unless otherwise specified within this chapter, the latest applicable BOCA codes shall be used in any construction phase of new sewer installations.
Old building sewer lines may be used or connected to when, upon inspection by the Borough, the old lines or pipes are found to meet current Borough specifications.
The Borough shall halt construction of any sewer line within the scope of the Borough's representation that presents an immediate safely hazard or violation of this chapter.
