DOUBLE WALL
FIBERGLASS
TANK SUMPS
Our double wall fiberglass tank sumps provide you with a
solution for virtually any type of tank top containment.
Manufactured using only the highest quality fiberglass
reinforced polymer (FRP), these sumps come complete with a
watertight sump shield and gasketed cover with strap-down
toggles to keep your containment free from costly liquid
intrusion. With options including 42" or 48" diameter, medium
or deep burial, octagonal base, bottom, two-piece configuration,
and double wall construction, you are able to select the exact
tank sump design to meet your specific site needs.
