Fittings 10" and larger shall be molded or fabricated in accordance wilh section 7.11 with ►nanufact(Irers standard pipe bells and gaskets. Wall thickness of fittings shall be SI)R 26 as defined in section 7.4.1 of the specifications. Gaskets for elastonteric joints shall be molded with a mirtirnum cross - sectional area of 0.20 square inches and conform to AS "rM F -477 specification. Fillings shall be manufactured by harco or equal. 4. All sanitary manholes shall be "precast concrete" manholes in accordance with AS'I'M C: -478 and Section 720. U -Rings shall conform to C -443. Kent Seal or equivalent shall also be applied to all joints and between riser rings and castings. Manhole step spacing shall be no more (hall 16- inches. 5. Mityl rubber coating shall be applied around each manhole joint from 6- inches above to 6 inches below each join(. The appropriate primer shall be applied prior to apt)lying the rubber. coaling. Inside joints to be filled with precoal plug material. 6. 'I'he casting elevalions are set by plan. however, the castings are to be adjusted in the Field by the Engineer's representative, should a discrepancy occur between plan grade anti existing grade. New manhole ring and cover shall be installed to establish grade. Maximum height of adjusting rings shall be 12- inches. 7. Backfill around all structures and all cuts tinder paved areas with granular material. 'Trenches opening within 5- feet of pave roadways shall be backfilled with granular material in accordance with Section 211.

The Contractor shall be required to furnish the develol►er's E=ngineer with a set cif prints, marked in red pencil, showing actual sewer location and invert, to include lateral location, depth and length. Such "as- built" prints; must be received by the i rigineer before the final contract payment can be authorized. 'I'lne sanitary sewer laterals and stubs lermination shall be indicated on the surface with a metal fence -'post set immediately above said termination point 10. All Sanilary sewer lines upon completion will be required to pass an infillralionyweir lest and a low pressure air lest, unless otherwise directed by the E=ngineer. Said test shall be condncled according to NCPI Standard Method, and shall be witnessed by an Engineer and representative of the Clay Waste District. 11. Deflection tests shall be performed on all flexible' pile after the (final backfill leas been in -place at least 30 days. No pipe shall exceed a vertical deflection of S percent tlefleclion test restills. (`Hie following are considered non- flexible pipes: concrete pipe, ductile iron pipe and cast iron pipe.) The deflection lest shall be performed with a nine - point mandrel. Proving rings shall be available. 12. All mandrel testing shall be observed by a Professional 1. :ngineer for cerlilicalion and a representative of the Clay Waste i)istrict. 13. The ends of laterals are to be plugged light with a braced plastic disc or cap capable of withslanding a low pressure air lest without leakage. 14. Iletlding for neAible pile shall be No. 8 crushed stone from 6- inches below the pipe to 12- inches above the pipe. Bedding for rigid pipe shall be No. 8 crushed stone from 6- inches below the 'pipe to the spring line of the pile and from this point to 12- inche3 above shall be fill sand or equivalent. Manholes shall lie plhced on no less Than 6- inches of No. 8 crushed slope bedding. 15. Water and sewer line crossings and separations shall be in accordance with 'I*en Stales' Standards. 16. 'french shall be opened sufficiently ahead of pipe laying to reveal obslnrction.s, and shall he prol►erly prolected and /or barricaded when left unattended. 17. No Water shall be permitted to flow into the sanitary sewer system durin¢ construction. Contractor shall utilize a pump to keep the water level below the pipe. Pump discharge shall be directed to a storm outlet. Any pipe entering existing sewers shall he plugged with mechanical screw type, braced plugged until such time as all tests on the sewers have been completed and the lines have passed all punch lists. 19, All newer lalersh inslalle(I by the mainline ('ontrarlor shall lie betided the male as the main line sewer. 19, forly -eight (48) hours notice shall be Riven to the Clay Regional Waste Dislricl prior to the start or sewer construction. Also, 48 -hours notice shall be given prior to any lesling clone on the sewer. 20. Manhole castings shall be stamped "SANI'i'ARY SI;WI :R" (Neenah Casting R 1642 or equal) and be self- sealing type. Waterproof castings shall be Neenah R-1916-Fl and stamped "Sanitary Sewer ". 21.
