Ace Roto-Mold 1,250 Gallon Septic Tank, part# AST-1250-1 is a 1 compartment septic tank. It's primarily used for the storage of wastewater. This plastic septic tank offers a lightweight low cost alternative to old-fashioned concrete septic tanks.

This 1250 gallon septic tank is constructed with rotationally molded polyethylene resin. It's seamless construction makes it durable and resistant to cracks, chips, and ruptures. The poly tank was made with FDA approved resin that complies with FDA standards 21 CFR 177.1520 (1) 3.1 and 3.2 for waste water storage.

The 1250 gallon septic tank features two 24" manway covers, a 4" gasketed pvc tee assembly inlet, and a 4" gasketed pvc tee assembly outlet. Installation requires a 25% internal backfill to equalize the pressure between the outside and the inside of the tank.
