PART 3: EXECUTION

3.1 WATERLINE INSTALLATION

A. General: All materials used in the water system shall be compatible for potable water systems. The pipe shall not be covered until it has been checked for leaks, except for the section of roadway that is required to be kept open as described in Section 02322.

B. Waterline Installation: Construct as shown on the drawing, and as recommended by the appropriate manufacturer. Install the curb valve with curb box and rod near the tank outlet to isolate the tank as shown on the drawings. Install brass nipples on each side of the curb valve with adequate length to extend outside of the curb box. Install a union on the downstream side of each curb valve/nipple as shown on the drawings.

C. Depth: Bury piping at minimum depth of 30 inches below finished grade and as needed to gravity flow.

D. Hose Connection Vacuum Breaker: Install on hydrant at a 45-degree angle to level ground as instructed by manufacturer.

E. Hydrant: Install according to manufacturer’s instructions, and as shown on the drawings.
