Precast Tank

Our Current Precast Tanks

We at Schwarr Industries pride ourselves on offering quality products at an affordable price. Our precast tank product offerings consist of Low-Profile Rectangular Septic Tanks, Round Septic Tanks, Aeration Tanks, Pump Stations, Cistern Tanks, Grease Interceptors and Storm Water Management Tanks. We can customize any tank to suite your needs.

All our tanks at Schwarr Industries use a Cast-A-Seal Connector on the inlets and outlets. The Cast-A-Seal 402/402F is a simple cast-in pipe-to-manhole connector that offers a watertight flexible connector that is cast into the structure when the concrete is poured.  The key lock is integrally cast-in during the production process providing a secure seal for storm water and sanitary collection system.
