ProSTEP™ Effluent Pumping System Packages from Orenco Systems are a proven, cost effective solution for transporting effluent in a wastewater collection and treatment system. Using patented* Biotube® filter technology, Effluent Pumping System Packages filter out solids so that only liquid from the "clear zone" between the tank's scum and sludge layers is pumped. This reduces biological loading and clogging of downstream components, extending drainfield life. All systems are pre-assembled with corrosion resistant, durable components, ensuring reliability.
