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.  Each vault includes a filter pack with a handle and a pump chamber.  The filter pack utilizes the deep pleated filter design of Clarus Environmental’s WW1 effluent filter, providing 528 linear feet of filtration area and a flow rate of 4,000 gpd.  The filter pack screens solids to 1/16”.  The vault’s inlet is specially designed to draw from the clear zone of the tank.
