Basins (Small Diameter Wetwells)

Benefits and Installation

Let us put our experience to work for you.  LFM has been building quality fiberglass reinforced manholes and wetwells since 1982.  We utilize the latest in chop and filament winding equipment, providing our customers with the highest quality fiberglass products on the market today.  Our production facility is located on 35 acres near Giddings, Texas and covers 83,000 ft2.

Light-weight

Fiberglass wetwells and basins by LFM are light-weight, making them easier to handle.  This means easier, safer, faster, and less costly installations.

Corrosion Resistant

The environment is always a concern when dealing with waste water systems.  Fiberglass basins by LFM are environmentally safe.  Our basins are corrosion resistant to waste water gases such as hydrogen sulfide.

Economical

Fiberglass wetwells by LFM are an economical value.  Our fiberglass wetwells have a longer service life than concrete wetwells.  As a result, the cost of repairs, disruptive excavations, and maintenance is minimized, saving you money over the long run.

ASTM Certified

Our fiberglass wetwells are built to meet the rigid requirements of ASTM Specification D3753.  LFM strives to supply its customers with the highest quality fiberglass wetwells available on the market today by meeting and exceeding all applicable ASTM requirements.

Quality Built Right In

LFM incorporates a comprehensive in-plant testing program.  Our quality control enables us to provide our customers with consistent workmanship in every fiberglass wetwell that we build.  We inspect and test each fiberglass wetwell before it is released for shipping.  Wall thickness reports, raw material analysis, and continuous chemical analysis reports are just some of the test procedures that we perform.  Testing reports are recorded and maintained at our office, and are available upon request.

Available Diameters

LFM builds fiberglass basins to your specified dimensions with standard diameters from 24” through 96”.  Depths are available from 2’ through 20’.  Greater depths can be custom fabricated.  Ask your LFM sales representative for details.

Connections

LFM can build fiberglass basins to fit your specific requirements complete with pipe stub-outs already in place, making installation and assembly easier and less time consuming.

Professional Delivery

LFM maintains its own fleet of delivery trucks, which lowers delivery costs considerably.  Our fiberglass basins are light-weight and can be easily loaded and unloaded on construction job sites.

Valve Boxes

LFM offers a fiberglass valve box that can be attached directly to the basin, making a one-piece fiberglass unit for lift station packages.  This saves time and money during installation.  The valve box is 48” square, with an open top with a 3” wide mounting flange.

Pump Mounting Bolts

LFM can install pump mounting bolts glassed into the bottom of our basins.  This allows easier installation of pumps into our basins.

Design

LFM’s fiberglass basins are built with a fiberglass anti-flotation bottom which has a 3” wide flange to counteract the effects of flotation after installation. Our basins also have an open top with a 3” wide mounting flange. The mounting flange provides a surface area to attach a cover to the basin. Upon request, we can also manufacture a fiberglass cover for our basins as well.

Quality Assurance

We stand behind the products that we build.  Our fiberglass basins carry a one-year limited warranty.  For additional information, see the warranty section of our brochure.
