Blue Roofs for Stormwater Control

September 30, 2010

BOSTON, Sept. 30 /PRNewswire/ — On Tuesday, September 28, 2010, New York City Mayor, Michael Bloomberg, spoke from the roof of P.S. 118 in Queens on technologies that the City will be considering to reduce stormwater flow impacts to wastewater treatment plants. One of the technologies, blue roofs, uses site-specific retention systems to mechanically slow the release of stormwater from roof surfaces to stormwater collection systems, thereby, reducing storm flows to the City’s 14 wastewater treatment plants. Blue roofs, used in combination with other “green” technologies, could significantly reduce high-volume pollutant loads stormwater flows from storm events onto the City’s waterways. These technologies could also provide significant cost savings to the City over the next 20 years according to the Mayor.

Geosyntec Consultants is working on a design team for NYC to pilot blue roof systems as part of a comprehensive technology demonstration program to address the issue of combined sewer overflow (CSO) and its impacts on stream water quality after major storm events. “The blue roof concept offers highly urbanized communities a new, practical tool for reducing the sudden impact of stormwater flows on CSO systems with the potential for significant long-term benefits to water quality,” stated Marcus Quigley, Geosyntec principal water resources engineer. “These systems have the additional benefits of being low cost with little to no interference to existing roof protection systems.” To find out more about Mayor Bloomberg’s remarks on New York City’s approach to CSO management, go to CBS New York, Reuters, or the Office of the Mayor’s official site.
