Sanitary sewer pipe shall be laid true to line and grade as set forth in Section 31, Paragraph 31-1.02 of the State Standard Specifications for Water and Sewer Main Construction. Dirt or other foreign material shall be prevented from entering the pipe or pipe joint during handling or laying operations and any pipe or fitting that has been installed with dirt or foreign material in it shall be removed, cleaned, and relaid. At times when pipe laying is not in progress, the open end of the pipe shall be closed with a water-tight plug or by other means approved by the Village Engineer to ensure absolute cleanliness inside the pipe.
(A) Laying of pipe on curves. The curvature of sanitary sewers is not allowed unless, in the opinion of the Village Engineer, special circumstances would allow otherwise. Pipe required to be laid on curved alignment shall be joined in straight alignment and then deflected, joint by joint. Special care shall be taken in blocking the pipe and in no case shall the degree of deflection exceed manufacturer's recommendations for the respective pipe size, material, and barrel length.
(B) Sanitary sewer services. Sanitary sewer services shall be a minimum of six inches in diameter and connected to the sewer main with a manufactured wye or tee and a 45 degree bend as shown on the applicable East Dundee Standard. Sanitary sewer services shall be extended to the property line or building at a minimum gradient of 1%. Sanitary sewer service connections to sewer mains 12 feet or more in depth shall be constructed with a six inch tee and riser and backfilled with select granular material. On a temporary basis, sanitary services may be terminated with a manufactured plug, in which case the location shall be staked and an accurate record kept of the distance from the nearest downstream manhole along the sewer main. Sanitary sewer service connections to existing sewer mains shall be made with a tapping machine and saddle tightly secured to the existing sanitary sewer or by other methods approved by the Village Engineer.
