Septic Tanks

These septic tanks are stronger, easier to install, and more cost-efficient than concrete alternatives. Made from HDPE with UV inhibitors, they feature a horizontal flow design for below-ground installation up to 36". Each tank has a unique serial code for tracking. These tanks are designed with quality controls and include a trapezoidal deep-rib structure and an interior baffle system for enhanced performance. A custom-molded nitrile rubber gasket ensures a watertight seal, while the lid locks in place with nylon ties, avoiding corrosion-prone metal fasteners. The unique baffle system slows wastewater flow, allowing solids to settle and partially treated liquids to exit for further treatment. Tanks of 1000 gallons or more are available in one or two-compartment designs. These tanks meet wastewater treatment standards. They naturally separate solids and liquids, effectively treating household wastewater.
