This spring, PWSA embarked on a $24 million investment in its covered reservoir, located in Highland Park. Constructed between 1897 and 1903, the Highland II Reservoir supplies water to portions of Squirrel Hill, Downtown, South Side, and West End. With a capacity of 125 million gallons, it is a crucial part of our water distribution system. As part of this project, PWSA’s contractor crews will remove the existing liner and cover and install a new liner, floating cover and supplemental equipment, like rainwater removal pumps.

Work began in March of 2022 and is estimated that it will be completed in December 2022.

This work is part of the Water Reliability Plan, a series of once-in-a-generation projects to renew key components of our water production and distribution system. After work on the reservoir is complete, it will be used as an alternative water supply point for other parts of our system that are taken offline for upgrades.
