The following standards shall be observed in the construction of connections to the village sewers:
(A) Acceptable pipe materials for conveying sanitary sewage.
(1) Polyvinyl chloride pipe.
(a) All polyvinyl chloride (PVC) plastic pipe shall conform to accepted current standards and specifications such as (ASTM) D 3034 standard specification, Type PSM polyvinyl chloride (PVC) sewer pipe fittings, DR (Dimension Ratio) 35, ASTM D 3212 standard specifications for sewer joints using elastometric seals. Pipe and fittings shall be made from clean rigid poly (vinyl chloride) compounds and chlorinated poly (vinyl chloride) compounds, having physical properties and chemical resistance of cell classifications for pipe of 12454-B, 12454-C or 13364-B, and cell classifications for fittings of 12454-B, 12454-C or 13343-C, conforming to ASTM resin specifications C 1784. All pipe shall have an integral and homogeneous bell end provided with a flexible gasket seal which is in compliance with the requirements of ASTM C 3139 or ASTM D 1869. Lubricant for joining pipe shall be NSF approved.
(b) Protective measures shall be taken during storage and handling of pipe to prevent direct exposure to the sun for extended periods of time.
(c) Polyvinyl chloride pipe shall be installed in accordance with ASTM Designation D 2321-74 “Standard Recommended Practice for Underground Installation of Flexible Thermoplastic Sewer Pipe.”
(d) Polyvinyl chloride (PVC) pipe, heavy wall gravity sewer pipe, SDR 26, pipe stiffness PD-115, conforming to ASTM D-3034 and ASTM F-679 or the latest revision, with push-on joints conforming to ASTM D-3212, shall be installed in all underground sewer systems greater than 12 feet below the ground surface.
(B) Acceptable pipe materials for storm sewers. Materials shall meet the requirements of those listed under § 603, storm sewers, and constructed in accordance with the construction requirements listed under that section of the “Standard Specifications for Road and Bridge Construction in Illinois,” latest edition.
(C) Manholes and special structures.
(1) (a) All manholes for sanitary sewers shall be precast manholes conforming with ASTM C 478 with a minimum diameter of 48 inches. Cones and sections shall be substantially free from fractures, large or deep cracks and surface roughness.
(b) Slabs shall be sound and free from gravel pockets.
(2) The floor of the manhole shall have invert channels formed at least one-half of the pipe diameter, with the floor of the manhole outside the channels sloped toward the channels not less than one inch per foot and not more than two inches per foot.
(3) All lift holes and joints between precast elements on sanitary sewer manholes shall be made with bitumastic material and/or mortar. No visible signs of infiltration/inflow will be allowed.
(4) All cast iron frames, covers and steps shall conform to the requirements of grey iron castings ASTM A 48. All frames and covers shall be provided with bolts for locking the manhole lid to the frame. No lids or frames, with holes open to the inside of the manhole, shall be allowed.
(5) Connection of flexible pipes to concrete sanitary manholes shall be with rubber connectors cast in the wall of the manhole.
(6) Manholes and catch basins to be constructed on “storm sewers” shall be constructed and installed in accordance with the Standard Specifications for Road and Bridge Construction in Illinois, latest edition.
(D) Allowable leakage. Before the village will accept the flow from any sewer system proposed to be discharged into the existing village sanitary sewer system, it shall be the responsibility of the owner of the system to satisfy the Superintendent that the pipe line or lines are not subject to infiltration leakage in excess of 200 gallons per inch of pipe diameter per mile per day and that no sources of surface inflow exist.
