Fiberglass Wetwells

Fiberglass wetwells have never been built this robust, anti buoyant or easy to install.

Fiberglass wetwells are 100% watertight, non corrosive, and maintenance free. Unlike concrete, fiberglass wetwells are delivered onsite as a singles piece unit regardless of its height. This eliminates labor intensive assembly practice that is commonly done when installing  concrete wetwells. Due to the Xerxes fiberglass wetwell rib structure, and bottom anti buoyancy flange, the wet well can be installed in shallow burial depths, regardless of the groundwater situation. Fiberglass wetwells can be buried in depths up to 50 feet.
