July 2022 Construction Update

After a pause in work due to significant shipment delays, SPU contractor crews resumed working on the Lake Forest Park Reservoir Floating Cover Replacement Project in May.

Since then, our contractor has received all engineered materials and had begun to install the floating cover on the west cell. The contractor will continue to deploy and install the cover and anticipates completing the installation in late August.

Remaining Construction Activities

The project is expected to be completed by fall 2022. Most of the remaining work will be focused on the west cell of the reservoir, and construction activities will include: 

• Installing the floating cover over the west cell of the reservoir and performing remaining equipment upgrades
• Bringing the reservoir back into operation once final inspection and testing are complete
• Final site restoration and demobilization

The reservoir is located in the Horizon View neighborhood of Lake Forest Park.
