Waluga Reservoir 2 (WR2) Construction Update

Crews work on the reservoir’s roof supports.

Roof shoring support has begun!

Now that the walls are complete, work has begun on the roof support. Next week, crews will continue to set-up roof shoring, and form the roof hatches and vents. They will also apply rubber along the top of the wall to help seal the reservoir once the roof is complete. The outside walls of the reservoir are set to be stripped and painted next week, however, this depends on the weather.

Beginning the first week of November, neighbors can expect to see several deliveries of steel in preparation for the final reservoir roof pour in mid to late November.
