Effluent Sewer — A Wastewater Collection Solution that is Cost-Effective and
Watertight effluent sewer systems are being recognized as one of the best solutions for the collection and transport of
wastewater to wastewater treatment plants.
They are ideal for communities of any size:
- New subdivisions
- Residential complexes
- Commercial properties
- Sewer expansions
- Ecologically sensitive areas
- Difficult terrain
- Phased build-out
Orenco has helped hundreds of communities around the world to design and construct reliable, watertight effluent sewers
with low-cost maintenance. Depending on the terrain, effluent sewers area frequently just half the cost of conventional
sewers, or less.
With effluent sewers, waste flows from the home or business to a watertight buried tank, where it is pretreated. Only the
filtered liquid is discharged. Solids remain in the tank for passive and natural treatment. Tanks typically need to be pumped
just once every 10 to 12 years.
Orenco (effluent-only) Sewers have been used on systems with up to 4000 connections and can be integrated into
traditional gravity sewer systems. Orenco Sewers are designed as a totally integrated package; the system components are
compatible and pre-assembled. Each piece is totally guaranteed, and the components are lightweight, durable, and resistant
