Why a Precast Concrete Septic Tank?

Precast concrete sewer products offer strength and durability for your wastewater management system. Stronger than tanks made of steel, plastic, fiberglass, or high-density polyethylene (HDPE), precast concrete septic tanks are known for their superior stability, performance and ease of installation -- not to mention, they’re environmentally friendly, too.

Shea Concrete Products produces precast residential and commercial grade septic tanks in many sizes, all manufactured in accordance with NPCA and ASTM C 1227 standards. Shea also offers a variety of products that are necessary for a completely functional septic system.

Our precast engineers design and build other precast concrete sewer products including distribution boxes, leaching chambers, manholes, pump chambers, tank extensions, and pagoda vents.
