River Intake Pump Station

Lake Oswego, OR

MWA worked with engineers to successfully design the River Intake Pump Station (RIPS) for the Lake Oswego/Tigard Water partnership within a short timeline.

This new concrete structure replaces a 1960’s era water intake serving the Lake Oswego community with water from the Clackamas River. The new pump station is seismically resilient, more energy efficient, has fish-friendly intake screens that allow safe passage to migratory fish, and has increased the capacity from 16 mgd to 38 mgd.

Designed to fit into an existing residential community, the RIPS also addresses security and durability issues at this exposed, publically accessible area. To effectively screen the large-scale pumping structure from passersby, a neighborhood-scaled and aesthetic gate structure presents a suitable, landscaped façade to its surroundings. Acoustic provisions were included in the design to reduce the impact of noise in the neighborhood. The pump station was designed with consideration to long term durability and the ability of workers to easily maintain it.
