As part of an urban Extension initiative that focuses on reducing storm water runoff from impervious surfaces, Rutgers Cooperative Extension installed 5,000-gal cisterns at the Department of Public Works (DPW) facilities in Clark Township and the Township of Parsippany-Troy Hills, New Jersey, to harvest rainwater from the rooftops of the garages at these facilities. This project intercepts rooftop runoff before it can carry nonpoint source pollutants from the land surrounding the DPW garages. The harvested rainwater is used to fill street sweepers, wash municipal vehicles, and supply water for a "green car wash" to support volunteer groups.
