Clackamas River Intake
Lake Oswego’s river intake, also known as the “raw water pump station”, was constructed in 1968, expanded in 1980, and upgraded in 2002. The facility pumps untreated “raw” water from the Clackamas River to a water treatment plant in West Linn. From there, treated drinking water is delivered to Lake Oswego residents.
The existing facility has some serious problems:
- The structure’s concrete floor is decaying and would be costly to repair.
- Pumps are decades old and suffer from chronic mechanical problems and breakdowns.
- Electrical and motor cooling systems are inadequate and cannot be upgraded within the existing structure.
- Reliable pump capacity is only 12 million gallons per day. Over the past decade, Lake Oswego’s summer peak day demand has regularly exceeded this limit.
Given these problems, upgrading and expanding the existing water intake facility is not a viable option.
A New River Intake Pump Station Under Construction
A new Clackamas River intake pump station, at the western edge of Chief Charles Ames Park, was approved by the Gladstone Planning Commission in 2011. Construction began in June 2013.
The new fish friendly water pump station will deliver water from the Clackamas River to the Lake Oswego Tigard Water Partnership’s water treatment plant in West Linn. The new facility will have the capacity to pump up to 38 million gallons per day (mgd) to serve Tigard and Lake Oswego customers, up from the 16 mgd capacity of the current facility. The new facility has a residential-looking façade, improved fencing, high quality building materials, a drinking fountain and native landscaping. It will be constructed just east of the existing pump station.
The existing facility will be removed. The raw water pipeline that carries untreated water from the intake facility to the water treatment plant in West Linn will also be replaced.

The Lake Oswego Tigard Water Partnership has won the first place Savvy Award from the City-County Communications & Marketing Association (3CMA) for its video about the horizontal directional drilling (HDD) process used to install 3,900 feet of water pipe under the Willamette River.

LAKE OSWEGO, Ore. – Being green is not easy, but the Lake Oswego Tigard Water Partnership was determined to incorporate energy-efficient elements in the design and construction of its $254 million water supply system.
