Pittsburgh, PA - The Pittsburgh Water and Sewer Authority (PWSA) Board of Directors awarded a Green Infrastructure (GI) contract for a project in the Banksville neighborhood to Independent Enterprises Inc. at today’s board meeting. The total project budget exceeds $1 million.
Construction is slated to begin in September 2016 for the installation of 15 new stormwater bioretention systems (bioswales) in the public right-of-way along the streets of Red Oak Drive, Hayson Avenue, Silver Oak Drive, and Silver Oak Place. This area has experienced repeated localized sewage basement flooding and this project will demonstrate that GI is an effective solution to managing both localized flooding and the region’s Combined Sewer Overflow (CSO) issues with one investment.
The project is within the Saw Mill Run Watershed, where 12 different municipalities, including the City of Pittsburgh, are collaboratively addressing water quality with a larger ongoing, GI-integrated watershed planning effort. Pre-construction and post-construction monitoring equipment will evaluate the performance of the particular GI methods implemented and quantify flow reduction within the adjacent sewer system. The monitoring results will also help verify and refine other upcoming modeling assessments in the overall City-Wide GI analysis.
PWSA’s GI Project in Banksville will occur in conjunction with a sewer improvement project on Hayson Avenue. The sewer improvement project commenced on July 8, 2016, and includes the installation of an 84-inch inline storage system. This two-part project of both the “gray” inline storage system and the “green” bioswales is scheduled to be complete by January 2017.
The Pittsburgh Water and Sewer Authority (PWSA) provides water and sewer services to more than 300,000 customers throughout the City of Pittsburgh and surrounding areas.
