Overview

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. Available in one and two-compartment designs, these tanks meet wastewater treatment standards. They naturally separate solids and liquids, effectively treating household wastewater.
