(A) A separate and independent building sewer shall be provided for every principal residential and/or commercial building; except, 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 considered as one building sewer.
(B) Existing building sewers may be used in connection with new buildings only when they are found, on examination and testing by the said town, to meet all requirements of this chapter.
(C) The building sewer shall be cast iron soil pipe, ASTM Specification C-700 extra-strength, polyvinyl chloride (PVC), ASTM D-3034 SDR 35 or other suitable material approved by the town in writing prior to use. Joints shall be capable of passing an infiltration test of 200 gallons per inch diameter per mile of sewer per day on a low-pressure air test. Any part of the building sewer that is located within ten feet of a well or water service pipe shall be constructed of ductile iron pipe or PVC Schedule SDR-21 with rubber ring joints. If the building sewer is installed in filled or unstable ground, the building sewer shall be suitably supported and need approval from the Inspector.
(D) The size and slope of the building sewer shall be subject to the approval of the town, but in no event shall the diameter be less than four inches. The slope of such four-inch pipe shall be not less than one-quarter inch per foot. Refer to A.S.T.M. and W.P.C.F. Manual of Practice. Additionally, there shall be clean-outs on the service laterals at maximum intervals of 100 feet.
(E) In all buildings in which any building drain is too low to permit gravity flow to the public sewer, sanitary sewage carried by such building drain shall be lifted by an equipment, facility or pollution control device approved by the town for conveyance of the private sewage to the public sewer.
(F) The town shall deny any permit if the information on the application is incomplete, inaccurate or indicates that the provisions of this chapter cannot be met.
