Waluga Reservoir 2 (WR2) Construction Update

Site restoration

The invasive plants have been removed around both WR1 and WR2, and crews have begun placing native trees, shrubs and plants around the site (pictured above). Over the next few weeks, crews plan to grade the site, continue installing irrigation systems, and install fencing and an entrance on Carman Drive.

WR1 – Testing Phase

Crews completed the improvements to the inside and outside of the reservoir and, last week, completed chlorination in prepartion for filling. WR1 is now in its testing phase and it’s expected to return to service next month.

Rock chipping

Around the reservoir site, crews will be rock chipping large boulders to break them into smaller, more manageable sizes and remove them from site. During this time, neighbors may notice an increase in noise. The piping near Parkhill is complete and the area has been backfilled (pictured above). The chainlink fence is no longer in place, however, the Partnership encourages residents to be cautious when walking on the trails to East Waluga Park and near the work site.

Did you know?

The new 3.5 million gallon WR2 utilizes seismic cable connections between tank walls as well as a foundation specially designed to move without cracking or leaking. Pre-stressed concrete is also used to increase resiliency as well as seismically-activated closure valves on inlet and outlet pipes, which protect against the tank emptying should connecting pipes be damaged.
