(A) Generally. Building sewer connections with any sewer main shall be made only at main or other such junctions as may be provided or designated by the village, and then only in such manner as directed by the village. The connection of the building sewer shall be made with a wye branch. The building service sewer shall enter the sewer main or lateral by way of a wye.
(B) Connection in absence of wye. In the event of absence of the wye, the connection to the sewer main or lateral shall be made by a qualified contractor using an insertion wye or wetting the main to install a wye fitting, following manufacturer’s recommendations.
(C) Plan. If another method is desired, a detail plan shall be submitted for review and approval by the village before the connection is made. Indiscriminate breaking of the sewer main pipe is not allowed.
(D) On-site inspection. After the wye branch has been inserted and jointed, and before any additional fittings have been placed in the service line, the installation shall be approved by the Sangamon County Water Reclamation District. After approval is granted, the contractor shall encase the work area as specified herein.
(E) Backfill. To be placed in accordance with the Standard Specifications for Water and Sewer Main Construction in Illinois, current edition. In addition, any building sewer crossing any street, or traveled alley be cradled with IDOT gradation CA-6, backfilled with IDOT gradation CFA-6 and the backfill mechanically compacted in six-inch lifts.
(F) Concrete encasement. When a riser is constructed and its height is four feet or more measured from the flowline of the sewer main to the top of the riser pipe, the wye connection shall be encased in concrete to a height of at least one foot six inches above the flowline of the sewer main. When the height of the riser is less than four feet above the flowline of the sewer main, the wye connection shall be backfilled to the top of the riser pipe with carefully placed and compacted granular backfill.
