precast concrete SEPTIC tanks & ACCESSORIES
While other tanks made from polyethylene deteriorate over time, concrete cures over time, making it a great material for strong and lasting septic tanks. Compared to concrete septic tanks, plastic tanks are prone to twisting, floating and other damage by seismic and buoyant forces.
Winchester Precast offers a wide variety of septic tanks that conform to Loudoun County specs that include Tuf-Tite 24" risers cast in place. All of our tanks are vacuum-tested and approved before they leave the yard. Details of septic system accessories we carry can be found here.
