Fiberglass Pit Liners and Sumps


Fiberglass Pit Liners and Sumps
Wilson Environmental offers premium-quality, fiberglass pit liners and sumps designed for wastewater collection and solids settling. We offer both design and equipment components for creating the appropriate wastewater collection and pre-treatment system for your wash bay and wash-water recycle or sewer discharge system.

A properly sized waste water collection system is key to a successful wash bay design or waste water collection system. The different fiberglass sump liners and pits are designed to:

Effectively pre-treat vehicle and equipment wash waters for discharge to sewer or discharge to a water reuse system.

Typical Wastewater Pretreatment Applications for Pit and Sump Liners

  • Meet local regulations for wastewater solids settling prior to discharge to the City Sewer.
  • Remove solids and free floating oils and greases prior to treatment for reuse or to discharge to sewer.

Why use a Fiberglass Pit Liner in your Wastewater collection system?

  • Fiberglass is chemically resistant to a wide variety of chemicals and cleaners commonly found in wastewater.
  • Fiberglass is good for high temperature wastewater applications up to 170 degrees Fahrenheit.
  • Provides secondary containment when properly installed.

Why not build a concrete sump or collection pit in place?

You can build a collection system completely out of cast in place concrete if you do it properly. Concrete containment for wet areas should be constructed according to the American Concrete Institute (ACI) 350 standards, specifically for wet or wastewater holding containment structures. Do not use ACI 318 standards, as the 318 standards are building construction. While good for building foundations, these standards are not recommend for wet areas where cracking is a concern. Ask your Civil Design Engineer or call Wilson Environmental for assistance.

Can I install the Fiberglass Collection Pit liners and fiberglass settling chamber in concrete?

Yes, and its easy to install. Fiberglass Pit liners and collection basins can be set in concrete. The fiberglass pit liner becomes your interior form saving both time and money.

Fiberglass Pit Installation

  • For installation excavate enough ground material to place the fiberglass pit liner in the excavation with approximately 6 inches on the bottom and sides to allow room for rebar.
  • Build the rebar cage around the pit liner before installing in the ground.
  • Set the pit with the rebar cage as a single piece.
  • Make your piping connections.
  • Check the level of the pit.
  • Fill the pit 2/3 with water to prevent the pit from trying to float when the concrete is poured.
  • Your ready to pour.

When set in concrete the fiberglass pit liner gives you an additional containment barrier to protect the surrounding soil and groundwater.
