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