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 large concrete pour over the wall forms in the cofferdam that was originally scheduled for early next week, has now been postponed until the week beginning December 2. After the pour, the wall forms will be removed from the bottom layer and reinstalled above the newly poured concrete. This work will continue over the next month. During the concrete pour, neighbors can expect some noise and an increase in truck traffic as 12-15 concrete trucks arrive at the site.
We apologize for the inconvenience this may cause. We wish everyone a happy Thanksgiving holiday.
To support the future access bridge, all 27 piles have now been drilled and installed in the ground at the river intake pump station (RIPS) site.
Work is now continuing on the forms for the RIPS walls and placement of reinforced bar in the bottom of the cofferdam. A large concrete pour is scheduled to occur around the wall forms the week beginning December 2. This should take about one day. After the pour, the wall forms will be removed from the bottom layer and reinstalled above the concrete. This work will continue over the next month.
During the concrete pour, neighbors can expect some noise and an increase in truck traffic as 12-15 concrete trucks arrive at the site. Generally, during the next three weeks, work hours will be 7:00 a.m. to 6:00 p.m. Monday through Friday, with no Saturday work expected. No work will occur on Thanksgiving Day or the Friday after.

Most of the subcontractors and suppliers—over 80%-- for the Partnership projects are being hired from local companies in local communities. The river intake pump station (RIPS) is no exception. On Monday, Partnership staff visited Fought & Company, Inc., Tigard, OR, the steel fabrication shop making the access bridge for the RIPS.
