Fanno Pump Station

Fanno Pump Station

In 2000, the City of Portland completed construction of the Fanno Pump Station, the Fanno Pressure Sewer and a gravity sewer line in SW Vermont Street. The Fanno projects replaced a system that relied on five old pump stations. The pump station is on SW 86th Avenue near the Portland Golf Club.

Environmental Services is designing a project to construct a new sewage pump station near the Fanno Pump Station to increase sewage pump capacity in the Fanno basin. The added capacity will ensure that the system can handle all wastewater flows during large rain storms.

The new SW 86th Avenue Pump Station will operate year-round and the existing Fanno Pump Station will operate in the winter to manage higher wastewater flows. Each facility will pump sewage through one of the two new 30-inch steel pipes that are part of the reconstructed Fanno Pressure Sewer. 

Pump Station Relief System

Until the city completes construction of the new SW 86th Avenue Pump Station, a temporary relief system will remain in place at the existing Fanno pump station. The system is designed to prevent uncontrolled sewage overflows during very heavy rainstorms by pumping wastewater out of the sewer, forcing it through a filtration system to remove debris, and discharging the wastewater into Fanno Creek until the heavy rains subside. If the relief system is activated, the city and Clean Water Services will post warning signs along Fanno Creek and notify local media.
