Features and Benefits

Clarus Environmental’s Centrifugal STEP (Septic Tank Effluent Pump) Vaults provide an economical way of adding a second compartment to an existing single compartment tank, eliminating the need to install an additional tank. Each vault is designed for use in simplex centrifugal pumping applications. With vault heights ranging from 46” to 63”, the centrifugal STEP vault can be customized for almost any project.

The filter pack screens solids to 1/16”. The vault’s inlet is specially designed to draw from the clear zone of the tank.
