Lake Oswego's previous river intake pump station (RIPS) was constructed in 1968. The facility pumped untreated "raw" water from the Clackamas River to the water treatment plant in West Linn. Although the intake was expanded in 1980 and upgraded in 2002, it had serious structural problems, was undersized to reliably serve peak water demand and could not be upgraded within the existing structure. A new river intake pump station was constructed just upstream of the previous pump station.

The new fish-friendly water pump station has the capacity to pump up to 38 million gallons of water per day (mgd), an increase from the 16 mgd capacity of the previous intake.

The new facility is designed with a residential-looking façade, improved fencing, high quality building materials and native landscaping. It is also designed and constructed to withstand a Cascadia subduction zone earthquake. .


Construction began in August 2013 on the new seismically resilient intake. The new pump station is now in operation, pumping water to the treatment plant in West Linn. The previous facility was removed in summer 2015 and final landscaping installed in fall 2015.

On November 9, 2015, a ribbon-cutting and celebration event was held in Gladstone to thank the community for their patience and support during construction.
