Pittsburgh, PA - On Saturday, February 16th, the Pittsburgh Water and Sewer Authority (PWSA) will receive the 2018 Sustainability Award from the American Society of Civil Engineers (ASCE) Pittsburgh Section for the Centre and Herron Green Stormwater Infrastructure project completed in June 2018. 
 
“We are honored to receive this award and to be recognized for the innovative solutions we are using to address Pittsburgh’s stormwater challenges,” stated Robert Weimar, PWSA’s Executive Director. “We are thankful for the opportunity the project provided to partner with the City of Pittsburgh, the Western Pennsylvania Conservancy (WPC), and the Allegheny County Sanitary Authority (ALCOSAN).  These partnerships are essential to the success of our growing stormwater program.”
 
About the Project
The Centre and Herron Green Stormwater Infrastructure project is located at the intersection of Centre and Herron avenues in the Upper Hill District. It directs stormwater runoff from surrounding streets into a 585 foot-long bioswale, where it is absorbed by plants or soaks into the ground. Additional stormwater is transferred through a series of pools and waterfalls that lead to underground storage tanks. The water from the underground tanks is slowly released into the sewer system.

This project is designed to capture the first one and a half inches of rainfall and it manages approximately one million gallons of runoff annually. The Centre and Herron project is one of three green stormwater infrastructure demonstration projects PWSA completed in 2018. 
Before the corner of Centre and Herron became an effective part of Pittsburgh’s water infrastructure, it was a vacant lot owned by the City of Pittsburgh. The City gave PWSA access to construct the needed stormwater infrastructure using the comprehensive approach to stormwater management identified in the Citywide Green First Plan
 
“The Centre and Herron project is an example of how we can transform vacant and underutilized public property into needed infrastructure and add to the character and aesthetics of a neighborhood,” stated Megan Zeigler, PWSA Associate Project Manager. 
 
The City of Pittsburgh has retained ownership of the site while PWSA operates and maintains the stormwater infrastructure. A third component of this partnership is with the Western Pennsylvania Conservancy. They maintain the landscaping and vegetation of the new bioswale, which is necessary for stormwater to begin infiltrating into the ground. 
 
During construction, WPC planted 13,473 perennials and 25 trees native or adaptable to Western Pennsylvania. This spring, WPC will call upon their strong volunteer network to replant and maintain the site. The partnership between PWSA and WPC is a unique example of how we can maintain other green stormwater projects throughout the city. 
 
PWSA and the Centre and Herron project team including the Wood Group, Environmental Planning and Design, and Vigliotti Landscape and Construction, Inc., are proud to receive this award and for the recognition from the Pittsburgh Section of the ASCE. The Centre and Herron stormwater project cost $1.09 million. It received funding from ALCOSAN’S GROW Grant program. 
 
Members of project team receiving award
 
“We were excited to select the Centre and Herron project for the ASCE Pittsburgh Section 2018 Sustainability Award,” stated Alma Rettinger, ASCE Pittsburgh Section Deputy Program Chair and member of the Awards Committee. “The project stood out for its use of green stormwater infrastructure, its volunteer-based maintenance strategy with the Western Pennsylvania Conservancy, and for improving greenspace within a neighborhood. It’s a project that demonstrates PWSA’s innovative approach to managing stormwater.”
 
In late 2018, PWSA started the design process for stormwater solutions in Four Mile Run, Negley Run, and projects in Saw Mill Run. For more information about PWSA’s stormwater projects, please visit pgh2o2030.com/stormwater.
