Basins & Wet Wells

Tall fiberglass basin, fiberglass basin, basin, wet well

Orenco Composites takes pride in producing high-quality, helically wound fiberglass basins. The helical winding process produces an extremely strong and uniform wall.  Resin-saturated fiberglass strands are wound onto a rotating steel mandrel’s surface in a precise helical pattern. The interior surface is a resin-rich layer (with optional gelcoat) that provides excellent corrosion resistance. After the fiberglass filament-winding process, gelcoat is typically applied to the exterior surface. Fiberglass reinforcement ribs, when required, are wound onto the basin exterior. Basins are designed to be buried to grade in completely saturated conditions without deformation.

An array of options is available to outfit the basin to your specific needs. We can supply a turn-key lift station, a simple basin with penetrations, or anything in-between.

Need a shelter and controls for your storm water or wastewater project? Let Orenco Composites deliver a complete, turn-key package. No other basin or wet well manufacturer can put it all together. And our quality is unsurpassed.
