Screened Pump Vaults manufactured by Orenco® are designed to
screen effluent for low-head effluent pumps in single-compartment
and two-compartment septic tanks and dose tanks. They include a PVC
vault, polyethylene effluent screen, and two support pipes. Screened
Pump Vaults are not typically recommended for use with high-head
effluent pumps. Contact Orenco for more information.
Note: If you are using a high-head effluent pump, we recommend using a Biotube Pump Vault instead of screened pump vaults.
Orenco Screened Vaults are used to screen effluent being pumped
from septic tanks in STEP systems and in on-site wastewater disposal
