PWSA finishes year-long Lanpher Reservoir improvement project

A nearly $9 million improvement project to the Lanpher Reservoir is complete after a year of repairs by the Pittsburgh Water and Sewer Authority.

The project began last spring after the state Department of Environmental Protection issued an administrative order requiring PWSA to expedite three water system improvement projects, including constructing a new liner and cover for the treated drinking water reservoir in Shaler.

Improvements were also made to the concrete wall surrounding the water storage facility.

The reservoir is divided into a West Cell and an East Cell. Restoration work on the West Cell was completed in August. The remaining East Cell upgrades were completed last week.

The Lanpher Reservoir can hold up to 146 million gallons of treated drinking water and serves customers in northern neighborhoods of Pittsburgh and Millvale.

This project is just one component of PWSA’s long-term water infrastructure improvement program. PWSA will begin building a new, four-mile transmission main connecting the Aspinwall Water Treatment Plant with the Lanpher Reservoir in late 2020.
