NYC plans green infrastructure to combat CSOs

Improvements would cut overflows at far less cost than traditional methods

The City of New York and its Department of Environmental Protection are taking a green infrastructure approach to reducing pollution to the city’s waterfront areas. Although local water quality has improved a great deal in recent decades, combined serwer overflows (CSOs) remain an issue.

Rather than simply do what most cities do – build tanks or deep tunnels to store wastewater until storms end – New York is also deploying a Green Infrastructure Plan that uses innovations like plantings, pervious pavement and streets, green and blue roofs and even rain barrels to trap stoprmwater before it gets to the storm/sanitary sewer systems.

The city’s green infrastructure plan aims to cut CSOs by 40 percent by 2030, and for about $1.5 billion dollars less than for traditional methods. Find out more at http://www.nyc.gov/html/dep/html/stormwater/nyc_green_infrastructure_plan.shtml
