Images provided by SPU are from recent construction activities after the reservoir was drained and the floating cover and liner were removed.

Seattle Public Utilities (SPU) Contractor Crews began construction on the Lake Forest Park Reservoir Floating Cover Replacement Project on May 17, and it is currently on schedule to be completed within about 6 months.

The reservoir is in the Horizon View neighborhood, near the park.

There are two large cells within the reservoir and each holds about 30 million gallons. This picture was taken at the bottom of the dividing wall of the East cell.

Since starting construction, contractor crews have:

• Installed a temporary access gate to help them bring equipment and materials in and out of the reservoir site
• Drained the reservoir and prepared the site for construction
• Removed and disposed of the existing liner and floating cover
• Prepared the site for installation of the new liner
• Started seaming and installing the new liner

In the coming weeks, the contractor will continue installing the new liner along the bottom of the reservoir. The liner will provide a protective barrier to preserve the quality of the drinking water that will be held in the reservoir.
