Including Watertight Sump Shields

Multiport Sumps

EBW™ brand Defender Series™ multiport sumps feature a solid fiberglass design and provide a watertight tank top containment solution for fill and vapor spill containers. Designed for use with Defender Series™ multiport manways, these multiport sumps allow you to reduce the number of forecourt manways for better site appearance and improved pedestrian safety. The two-piece design eliminates confined spaces and gives installers full access to the containment during installation. The octagonal base design features eight flat panels molded together which provide ideal installation surfaces for 90° pipe entries. Each package includes a watertight sump shield, a sump reducer, the appropriate size and quantity of Neoprene boots and clamps.

  • Constructed from rugged three-layer hand layup fiberglass with a white vapor and watertight gel coat interior for added protection and increased visibility.
  • Sump reducers are available to fit under both 32” and 42” manways.
  • Double wall models are shipped under vacuum with vacuum gauge installed for on-site verification of a sealed interstitial space.
