PART 3 EXECUTION

3.01 INSTALLATION

A. General Requirements:

2) Bottom (Invert) of Water Piping:

(a) Minimum 18 inches above top (crown) of sewer piping.

(b) Where this vertical separation of 18 inches above top (crown) of sewer piping cannot be obtained, the installation will be acceptable only when sewer piping is constructed of AWWA approved water pipe and pressure tested in place without leakage prior to backfilling.

d. Water Piping Crossing Sewer Piping:

1) Crossing Under:

(a) Where water lines cross under gravity sewer lines, encase sewer line fully in concrete for a distance of at least 10 feet on each side of the crossing, unless sewer line is made of pressure pipe with rubber gasketed joints and no joint is located within 3 feet horizontally of the crossing.

2) Crossing Over:
