The HDPE tanks shall have a minimum capacity of 5,000 gallons, a maximum diameter of 12-ft, and shall be designed for containment of liquid. The tank shall be impact and corrosion resistant. B. The polyethylene compound shall be suitably protected against degradation by ultraviolet light by means of carbon black, well dispersed by pre-compounding in a concentration of not less than 1.5 percent. C. The HDPE tanks shall include an inlet near the top and an outlet that is at an appropriate height above ground to allow draining liquid from the tank into a water truck. PART 3 EXECUTION 3.1 GENERAL A. All polyethylene pipe shall be cut, fabricated, and installed in strict conformance with pipe manufacturer's recommendations.

Pipes shall be stored on level ground, preferably turf or sand, free of sharp objects that could damage the pipe. Stacking of the polyethylene pipe shall be limited to a height that will not cause excessive deformation of the bottom layers of pipes under anticipated temperature conditions. Where necessary due to ground conditions, the pipe shall be stored on wooden sleepers, spaced suitably and of such widths as not to allow deformation of the pipe at the point of contact with the sleeper or between supports. 3.4 HANDLING PIPE • A.
