Highland II Reservoir: Liner and Cover Replacement

Completed Water Reliability Plan

The Highland II Reservoir Liner and Cover Replacement includes the demolition and removal of the existing liner and cover and installation of a new reservoir liner, floating cover, and supplemental equipment such as the rainwater removal pumps and associated piping on the floating cover.

Progress & Status

Construction Complete

Replacement of the liner and cover was completed in late 2022.

The replacement of the liner and cover is part of our Water Reliability Plan. It will meet water safety and regulatory requirements and create greater reliability within our water distribution system. The reservoir will be used as a temporary clearwell while the new clearwell is being constructed. The replacement of the liner and cover is the largest project of this type happening in 2021 and 2022.
