Fiberglass Basins



Steele Plastics Inc. manufactures different fiberglass basins for different applications. We manufacture a tapered, one piece fiberglass basin with a maximum size of 48" X 72". We also manufacture a straight wall, filament wound fiberglass tank in standard diameters up to 72" and 30 feet deep. The filament wound tanks are also used to build attached valve box systems.

Aluminum Hatch Cover

Wastewater Covers



Steele Plastics Inc. manufactures fiberglass, aluminum, and steel covers to fit all our basins, as well as custom designed to fit your application.  Aluminum and steel covers are built using a CAD driven plasma burning table to insure the most exacting tolerances.  Most of our fiberglass covers are standard stocking items, and we have multiple options for all our covers including; vent grommets, vent couplings, mushroom vents, and level control modifications for mounting float switch cords thru the cover using compression cord grips.  Standard paint for the steel cover is Industrial Grade Polyurethane.  Coal Tar Epoxy paint is an available option.  Fiberglass covers are available in Tan gel coat, Green gel coat, and Pigmented Natural Resin color.

  Fiberglass Risers



Steele Plastics manufactures fiberglass Risers/Extensions in 24" - 72" Diameters and up to 48" deep. They are primarily used for basin risers/extensions, but can also be used for valve vaults where a bottom is not required.

Note: Depths greater than 48" may be available - contact factory


Extension/Riser Drawing

Extension/Riser Specification




Steele Plastics Inc. basins are designed, and built, to be installed with the top flange flush with the top of the ground.  When an extension is added to the top of the basin, it effectively buries the original tank deeper than it was designed to be installed.  Many of our customers, thru their own experience and knowledge of the job site, choose to add an extension or “riser” to an existing installed basin.  Steele Plastics Inc. does build and sell extensions on a regular basis.  However, it must be clearly understood that the application of the extension is solely at the discretion of the purchaser, and that the warranty on the original basin that the extension is attached to, is null and void.
