Part II: Products

2.01 Double-Wall Fiberglass Underground Tanks

A. Product-Storage Requirements:

All primary tanks must be vented. Tanks are designed for operation at atmospheric pressure only.
Tanks shall be capable of storing landfill leachate of specific gravity up to 1.1 with temperatures not to exceed 150°F at the tank interior surface.

B. Loading Conditions - Tanks shall meet the following design criteria:

External hydrostatic pressure: Buried in ground with 7' of over burden over the top of the tank, the hole fully flooded and a safety factor of 5:1 against general buckling.
Surface Loads: When installed according to manufacturer’s current installation instructions, tanks will withstand surface H-20 axle loads (32,000 lbs./axle).
Internal Load: Primary and secondary tanks shall withstand 5 psi air pressure test with 5:1 safety factor.
Tanks shall be designed to support accessory equipment such as heating coils, ladders, drop tubes, etc. when installed according to manufacturer’s recommendations and limitations.
Tank laminate shall include silica treated with silane.

C. Interstitial Space: In all double-wall and triple-wall tanks, there shall be a space between the primary and secondary walls to allow for the free flow and containment of any leaked product from the primary tank. The space shall also allow room for the insertion of a monitoring device.

D. Service conditions:

Each tank and application must have prior approval from CSI, including any limitations on use and design.
A CSI Chemical Tank Application form must be completed for each tank and submitted to CSI for prior approval.
