Biotube ProPak from Orenco Systems are complete, ready-to-install pump packages in a box. They include a Biotube filter cartridge that filters up to two-thirds of solids. Only liquid from the tank’s clear zone is pumped, significantly reducing the load on the drainfield. Biotube filters are easy to remove and clean without pulling the pump vault. They can be used for filtering and pumping effluent from single- or dual-compartment septic tanks to gravity or pressurized discharge points. Their pump vault technology eliminates the need for a separate dosing tank, reducing system cost and footprint. 800/348-9843; www.orenco.com.
