Pittsburgh’s $193 million ABC Project targets critical underground water infrastructure
The Pittsburgh Water and Sewer Authority (PWSA), now rebranded as Pittsburgh Water, has announced a sweeping $193 million investment to modernize its critical water infrastructure through what it calls “The ABC Project,” CBS News reported. Designed to improve regional water reliability and resilience, the initiative represents one of the largest infrastructure upgrades in the utility’s history.
The project’s title reflects its three major components — the Aspinwall Pump Station, the Bruecken Pump Station, and the Clearwell Bypass, each of which will undergo significant rehabilitation or replacement. Together, these systems form a central part of Pittsburgh’s water delivery network, which serves hundreds of thousands of residents across western Pennsylvania.
At the Aspinwall Pump Station, the oldest of the three facilities, crews will conduct a full modernization of pumps, motors, electrical switchgear, and piping. Across the river, the Bruecken Pump Station will be replaced with a new energy-efficient structure housing advanced controls and upgraded security systems.
The Clearwell Bypass is another major element, enabling PWSA to temporarily reroute flow around the city’s 44-million-gallon underground disinfection basin — a facility that has operated continuously since 1913 — to allow for its complete replacement. The bypass will include the installation of new 144-inch and 84-inch diameter transmission mains, CBS News reported.
According to PWSA officials, the ABC Project will not only strengthen the city’s water reliability but also deliver significant regional benefits. The authority estimates the program will create more than 1,000 construction and engineering jobs and generate over $300 million in economic impact. Funding for the project combines state grants with low-interest infrastructure loans.
Construction for the ABC Project is already underway, with completion targeted for 2029. Once finished, the upgrades will enhance operational efficiency, extend the lifespan of critical assets, and position Pittsburgh’s water system to meet future population and climate challenges.
