CSI - Manholes or Lift Stations

Flowtite Fiberglass Wetwells were developed over twenty-five years ago. Since then, thousands of our wetwells have been installed in the U.S.A., in many different types of soil, and in many different effluents, without a single failure. Flowtite Wetwells have stood the test of time.

This should not be surprising. Flowtite Fiberglass Wetwells have the corrosion resistance, strength, monolithic design, and lightweight, which make them ideal for any wastewater application. Flowtite Fiberglass Wetwells put an end to worry about infiltration/exfiltration at this critical station in a sanitary sewer line. The monolithic construction of the Flowtite Wetwell has no sidewall joints, sections or seams to let ground water in or waste out. And because it is highly resistant to corrosion, you’re assured that Flowtite Wetwells will provide long-lasting performance.

We use only the finest quality resin and glass. Plus, we add chemically enhanced silica to improve corrosion resistance, strength, and overall performance. These materials are then centrifugally cast to form the very best wetwell available today.

Flowtite is a name you can trust. Formerly a division of Owens-Corning, the world’s largest fiberglass producer, we are committed to continuing our tradition of excellence. After all, we have been manufacturing underground tanks and wetwells for over twenty-five years and we want to continue to earn your trust, just as we have for over a quarter of a century.

Eliminates Corrosion and Eliminates Costly Maintenance/Rehabilitation

Corrosion is the mortal enemy of wetwells, but not of Flowtite fiberglass. Even decades of attack by hydrogen sulfide has no effect on Flowtite Wetwells. As a result, you avoid the service disruption and costly repairs and maintenance associated with ordinary wetwells.

Structurally Sound - Exceeds H-20 Load Rating

Fiberglass wetwells have been in service for more than twenty-five years. Some of these installations are in streets. Flowtite wetwells can be installed in traffic locations. Flowtite wetwells are designed to meet or exceed the requirements of ASTM D 3753. They can be installed in a variety of soil conditions. Each wetwell is designed to withstand the hydrostatic head to grade with the wetwell completely empty.

Ease of Installation

Flowtite wetwells are far lighter than concrete – about 125 pounds per vertical foot. The light weight of the Flowtite wetwell combined with its one-piece construction, provide the contractor with one-step installation. Completely constructed at the factory, Flowtite wetwells eliminate time-consuming concrete forms or multiple pre-cast concrete sections.

Reduce Infiltration

In most cases, ordinary concrete wetwells are installed in sections; otherwise they would be too heavy to move. This creates a joint – the source of most leaks – every three feet. Flowtite wetwells have no joints. They are available in standard one-piece lengths from 3 to 35 feet. This prevents infiltration or exfiltration. The monolithic design also makes installation easier by reducing the time necessary to complete joints between sections.

Will Not Float

Flowtite fiberglass wetwells have a better Safety Factor against float-out than concrete wetwells. The Flowtite fiberglass wetwell has a wall thickness far less than concrete wetwells, resulting in a decrease in volume displacement of the unit. As a result, the buoyant forces on Flowtite fiberglass wetwells are less than concrete wetwells.
