(B) The connection of the building sewer into the public sewer shall conform to the requirements of the Building Code or other applicable rules and regulations of the municipality.

(1) Connections made to a sewer line without an existing wye branch shall be made using a saddle wye connection by experienced workmen under the supervision of the Superintendent.
(2) Connections to a wye with a depth greater than needed to obtain proper slope on the building sewer may be resolved by constructing a riser connection. The riser pipe shall consist of the sewer pipe placed on a steep slope by the use of 45 degree bends. The riser pipe shall then be encased with concrete at a minimum thickness of six inches around the pipe. The placement of riser pipe shall be made by experienced workman under the supervision of the Superintendent.
(3) The building sewer shall not be less than six inches in diameter with a slope of not less than 1/8 inch per foot.

(5) Backfill outside of paved areas shall consist of carefully selected excavated material free from debris, frozen material or stones larger than two inches in diameter.
(6) Backfill under paved areas shall consist of approved granular material placed and compacted as directed by the Superintendent.
(7) Sewer materials shall conform to the following American Society for Testing and Materials specifications as follows:
C-700-78(a) Standard strength clay sewer pipe C-700-78(a)
Extra strength clay pipe C-425-77
Compression joints for vitrified clay bell and spigot pipe
C-76-78 Reinforced concrete sewer pipe (eight-inch pipe and above)
C-443-78 joints for circular concrete pipe
Six-inch P.V.C. ASTM F-789-82
Six-inch P.V.C. S.D.R. 35 ASTM D-3034
(D) Whenever possible, the building sewer shall be brought to the building at an elevation below the basement floor. 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 approved means and discharged to the building sewer.
(E) The applicant for the building sewer permit shall notify the Superintendent when the building sewer is ready for inspection and connection to the public sewer. The connection and testing shall be made under the supervision of the Superintendent or his representative.
