Corcoran Precast Tanks manufactures & supplies precast septic tanks for domestic and commercial use.

Precast Tanks

We manufacture and supply a variety of septic tank sizes. Our shallow tank design allows for placement in areas where bedrock may be a problem as the need for excavation depth is greatly reduced when compared to competitor’s tanks. Our septic tanks consist of two chambers, where wastewater enters the first chamber of the tank, allowing solids to settle and scum to float. The settled solids are anaerobically digested, reducing the volume of solids. The liquid component flows through the dividing wall into the second chamber, where further settlement takes place. The excess liquid then flows from the outlet to the percolation system where it is distributed to the subsoil.
