How does Cortlandt Des compare with other water systems in Westchester County?
By EPA's size categories, Cortlandt Des is a very small system (500 people or fewer). Westchester County has 273 active public water systems.

Across New York, the 8,167 active systems average 2,374 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Cortlandt Des is well below that figure.
What does “non-transient non-community water system” mean?
A non-transient non-community water system regularly serves at least 25 of the same people for more than six months a year, but not where they live. Schools, factories, office buildings and hospitals with their own supply are typical examples. New York has 704 active non-transient non-community water systems, 8.6% of the state's 8,167 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 7,096 New York systems (87%) list groundwater as their primary source.
Who owns and regulates Cortlandt Des?
EPA lists Cortlandt Des as owned by a local government. The NY state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 77 of the 273 active systems in Westchester County (28%) are also owned by a local government.
