The subdivider must obtain approval from the Village Engineer of the water system design before any subdivision construction is started.
(C) Water mains and appurtenances shall be installed in accordance with the village construction standards and with the most recent edition of Standard Specifications for Water and Sewer Main Construction in Illinois. Connection of new water mains to the existing system shall not be made until approved by the Village Engineer.
(D) Water mains shall be CL350 Tyton joint ductile iron pipe, or polyvinyl chloride (PVC) with a minimum rating of DR18 PC 235 psi. Iron pipe size SDR21 or SDR26 is not permitted.
(E) A locating tape (tracer wire) shall be installed with all PVC water mains. Tracer wire shall have an HDPE jacket; THHN coated wire is not allowed.
(F) Gate valves and boxes shall be provided to adequately valve the water system.

(K) All other water main trenches shall be compacted by mechanical compaction, jetting and water soaking or another means, as approved by the Village Engineer.
(L) All new water mains and appurtenances shall be visually inspected, disinfected, pressure tested and leak tested. The testing shall be done by the subdivider’s engineer or an independent testing company under the observation of the Village Engineer. The system must pass all tests prior to being connected to the municipal water system.
(M) All water main and service construction shall be performed in accordance with the Standard Specifications for Water and Sewer Main Construction in Illinois, latest edition.
