The pipe shall be made to accommodate rubber gasket joints in accordance with ASTM Standard C-443. The interior of concrete pipe shall be coated with a material that is non-reactive with sewer gas or any other material allowed in the waste stream.
(B) Materials for service sewers (six inches in diameter) and building sewers (four inches in diameter) shall be:
(1) Extra Strength Vitrified Clay Pipe (ESVCP) generally conforming to ASTM Standard C-700. The joints for the pipe and fittings shall consist of a PVC ball or collar securely fastened at the factory on the bell end of the pipe in such a manner as to be water- and air-tight, and a polyurethane compression sealing element securely fastened at the factory on the spigot end of the pipe. The joints shall generally conform to ASTM Standard C-425. The material in the PVC bell and collar shall generally conform to the requirements of ASTM Standard D-1784. Pipe with clay bells will not be allowed;
(2) Polyvinyl chloride (PVC) pipe (four through 15 inches in diameter) generally conforming to ASTM Standard D-3034, type PSM, with minimum wall thickness standard dimension ratio (SDR) of 26 and push-on flexible elastomeric seal joints conforming to ASTM Standard D-3212;
(3) Ductile-iron pipe (refer to the requirements of § 153.166(B)(1)); or
(4) Acrylonitrile-butadiene-styrene (ABS) composite pipe (six through 15 inches in diameter) generally conforming to ASTM Standard D-2680 with flexible elastomeric seal joints conforming to ASTM Standard D-3212; ABS solid wall pipe (four and six inches in diameter) generally conforming to ASTM Standard D-2751, with a minimum wall thickness standard dimension ratio of 23.5 and push-on flexible elastomeric seal joints conforming to ASTM Standard D-3212.
(C) All forcemain pipe shall be constructed of ductile-iron pipe or pressure class plastic pipe as defined in § 153.166(B) of this chapter.
(D) Materials for manholes shall be:
(1) Leak-tight (including pipe entries) and shall be constructed according to the standard details. All manholes shall have an inside diameter as shown on the drawings. Brick manholes will not be allowed. Manholes shall be constructed of precast reinforced concrete manhole components in general conformance to ASTM Standard C-478. The use of concrete masonry units, complying with ASTM Standard C-139, for manhole barrel sections shall be subject to the authorization of the Village Engineer on an individual basis. No bitumastic materials shall be used in the construction of the manholes.
(2) The base shall be an eight-inch thick monolithic unit with welded wire fabric reinforcement.
(3) Precast barrel and cone components: manhole joints shall be compression type utilizing rubber “O” ring gaskets. The barrel thickness for four foot-diameter manholes shall be 5.75 inches (wall C); for five foot-diameter manholes, 6.75 inches (wall C); for six foot-diameter manholes, seven inches (wall B). No bitumastic will be used to seal manhole joints. Cones shall be eccentric. Pipe entry holes shall be precast in the barrel sections. Sanitary manhole pipe entries shall be water-tight compression joints utilizing rubber gaskets compatible with the pipe being used.
(4) Precast concrete flat tops required for manholes shall be manufactured according to the standard details of the IDOT.
(5) Concrete masonry units may be used for manhole construction if authorized by the Village Engineer. Masonry unit manholes shall be built with mortared joints, upon a flat base component.
(6) Steps shall be set into the manhole walls at the time when the manhole walls are cast. Steps shall be set at 16 inches on centers. The manhole step shall consist of a three-eights of an inch steel reinforcing rod encapsulated in polypropylene plastic. Fiberglass and cast iron steps are not allowed.
(7) Each manhole shall have the frame, lid, or grate as specified in this chapter or shown on the standard drawings. All closed lids shall have concealed pickholes and shall be self-sealing with rubber gasketed lids. Castings for sanitary manholes installed in streets or traveled surfaces shall be Neenah Model R-1713; or equivalent. Castings for sanitary manholes installed in yard areas (areas not expecting heavy loads) shall be Neenah Model R-1772A; or equivalent.
(8) All pipes connected to manholes and inlets shall be cut to fit with a concrete saw or similar saw. Breaking off pipe sections with hammers, chisels, or chains will not be allowed.
(E) Cleanouts shall be constructed as shown on the standard drawings, and shall include a wye fitting, piping, plug, concrete encasement, a concrete pad, and a cast iron cleanout ferrule and brass plug.
(F) Fittings shall be the same type of material as the pipe. All joints shall be water-tight and gas-tight. Connections between different pipe materials shall be made with a manufactured coupling.
(G) Sewer taps to existing sewer lines shall be constructed as required by the Village Engineer utilizing manufactured fittings and couplings, and shall be made water-tight. Sewer taps to existing sewer lines shall be inspected by the Village Maintenance Superintendent before they are encased or backfilled.
