Biotube® Pump Packages by Orenco are complete, integrated packages for filtering and pumping effluent from single- or double-compartment septic tanks and pump basins. Orenco’s patented Biotube vault technology filters up to two-thirds of suspended solids from the tank or basin's “clear zone.” This reduces biological loading and clogging of downstream components, saving money on O&M and helping extend the lives of drainfields and other downstream components.
