GSE Grade-Level Transition Sump

The new OPW GSE Grade-Level Transition Sump is an at-grade system that utilizes the fiberglass DSE base with a powder-coated steel top. The top features a lockable access hatch and is sloped for water-shedding.

The smooth walls inside and out of the DSE base allow for a more secure bond with pipe entry fittings.

The GSE is an ideal transition sump for aboveground storage tank (AST), aviation, marina, fuel oil and generator applications. It can also serve as a multi-purpose junction box for various fuel, chemical, water and electrical installations.

The GSE Includes:

  • Fiberglass DSE Base
  • 14-Gauge Powder-Coated Steel Top
