Pittsburgh Water and Sewer Selects HMM for Program Management Contract

The Pittsburgh Water and Sewer Authority (PWSA) has chosen North American engineering firm Hatch Mott MacDonald for a three-year contract to provide program management services for its multi-year water and capital improvement program. The contract, which covers projects with an annual value between $50 million and $75 million, may be extended for an additional two years.

Hatch Mott MacDonald will assist the PWSA with implementation of its capital program ? including a $30 million project to rehabilitate 18 rapid sand filters at the PWSA?s water treatment plant along Freeport Road adjacent to Aspinwall Borough. The treatment plant is the primary treatment facility located along the Allegheny River.

Hatch Mott MacDonald will also assist the PWSA in complying with the terms of a Consent Order from the Pennsylvania Department of Environmental Protection, calling for the reduction of combined sewer overflows (CSOs) into the Allegheny, Monongahela and Ohio Rivers. The PWSA?s plan includes a Saw Mill Run demonstration project, a key component of the Authority?s initial four-year capital plan. Saw Mill Run will test the efficiency of alternative approaches to reducing stormwater runoff.

?HMM has a successful track record of assisting urban sewer and storm water managers in implementing Combined Sewer Overflow and stormwater controls, including gray and green infrastructure,? said President and CEO Nick DeNichilo. ?We are honored to have the opportunity to apply our experience to the challenges facing the PWSA.?
