Orenco's injection-molded fiberglass-reinforced polyester (FRP) septic tanks* set a new onsite
industry standard for strength and watertightness.
They are available in the following sizes:
The tanks are light enough to transport in a pickup or small trailer and install with a backhoe, yet are far more rigid than polyethylene tanks. In fact, they're strong enough to withstand a four-foot burial depth empty.
In the 1000-gallon and 1500-gallon tanks, a baffle wall can be installed anywhere in the tank to create two or more compartments of suitable volume for the application.
Orenco's innovative injection molding process creates tank halves with a quality and consistency no one else can match. After molding at Orenco, Orenco Fiberglass Tanks are assembled by a regional network of factory trained and authorized assemblers. They test every tank for watertightness before shipping the tanks to installers or to Orenco tank wholesalers in their regions.
