Two quadrants left to pour for the WR1 roof

Waluga Reservoir 1 Roof Replacement Construction Update

In mid-February, crews poured the first quadrant for the WR1's new roof! The roof is being poured in a checkerboard pattern, one quadrant at a time. Each quadrant requires 256 cubic yards of concrete to be poured, about 25 concrete truck loads in one day!

Crews are now at the halfway mark with two of the four quadrants poured. Weather permitting, the final two quadrants will be poured early-mid next week!

Recent Cryptosporidium Detections in Portland Bull Run Water

The Portland Water Bureau recently detected the presence of Cryptosporidium, a potential pathogenic microorganism, in several samples collected at their Bull Run intake in January and February.

Although our water systems are close to Portland’s, the City of Lake Oswego and Tigard Water Service Area customers receive their drinking water from a different source and the treatment process is also different than Portland’s. Lake Oswego and Tigard Water Service Area’s primary water source is the Clackamas River. The recently upgraded filtration system at our water treatment plant removes Cryptosporidium and pathogens that may be detected in the Clackamas River water supply. Ozone, a powerful oxidant, also provides an additional treatment barrier to protect public health.

Only one truck will enter the site on Carman Drive at a time, unload crane materials and then exit, before another truck then arrives to the site. Five trucks are expected to deliver parts for the crane.
