Xerxes Oil / Water Seperators

ANOTHER INNOVATIVE SOLUTION FROM XERXES With the introduction of the underground fiberglass oil/water separator, Xerxes continues its reputation for innovation. Xerxes was the first to make fiberglass underground tanks with integrally constructed ribs dramatically increasing their robustness - and the first to make a fiberglass underground double wall tank. With the oil/water separator, the innovation continues. And it couldn't have come at a better time.

SOLVING A GROWING ENVIRONMENTAL CHALLENGE Today, there's Increasingly more regulatory concern than ever with the impact/effects of storm water run-off. The new Xerxes oil/water separator is:

  • Cost-effective
  • Rust-proof
  • Lightweight
  • Made with a patented coalescer that's effective and easy to maintain
  • Designed to meet or exceed EPA standards
  • Backed with a 30-year limited warranty
