Clean Water Westchester Symposium

Planning for a Cleaner Water Future for Westchester County –
Our “Green Apple”


This January, local, county and state government representatives met with environmental leaders and the private sector, to discuss a greener future for Westchester County’s wastewater system. The Clean Water Westchester conference explored new ways to finance, manage, and govern wastewater collection and treatment, aimed at improving our current system and achieving better environmental outcomes – including cleaner waterways and a reduced carbon footprint.

County Executive George Latimer set the tone for the day with his stated commitment to consolidate sewage collection in Westchester under County leadership and management, an approach that  Save the Sound supports.

He said, “We need a singular system that has an understanding that all the wastewater that’s generated from Peekskill to Pelham to Pound Ridge has to be dealt with in a singular fashion, and those local governments have to be relieved of that burden. And when the county government takes on that burden, which we should do, we should have a partner in the federal government to help us do that.”

Executive Latimer called for Westchester to take a longer view of our wastewater needs and plan for the next 50 to 100 years. That means planning for the oncoming challenges of increasing population and climate change impacts including more intense, frequent storms and lower drinking water reserves.
