Buffalo, NY is a large city, with a population near 258,071 and the 7th-largest community in New York. Like much of New York, Buffalo draws its water primarily from Catskill/Delaware watersheds, Great Lakes, and aquifers.
Buffalo's water outlook is shaped most by aging infrastructure — the issue that dominates planning across New York. NYC's protected upstate watershed delivers unfiltered water, but upstate systems face PFAS (notably Hoosick Falls) and aging mains.
Buffalo sits in a state that reuses roughly 3% of treated wastewater (minimal programs) and currently experiences abnormally dry to moderate drought.
