Fiberglass Wastewater Tanks 

The simple truth- Most tank suppliers take orders for products without providing service or technical aid. To us providing a fiberglass wastewater tank is only as important as the rest of the system.

We calibrate the equipment on the fiberglass wastewater tank to be as seamless as possible with the rest of the system.

The list of "why" you would choose a fiberglass wastewater tank over a concrete tank is long. However the bottom line is the fextex fiberglass tank is 100% water tight. 

Fextex understands concrete tank manufacturers claim the same thing; but ask yourself one question. If concrete is truly 100% watertight then why don't they build concrete underground petroleum or chemical tanks?

We are  on the Washington underground tank approval list
