How does Mayflower Inn compare with other water systems in Litchfield County?
By EPA's size categories, Mayflower Inn is a very small system (500 people or fewer). Litchfield County has 346 active public water systems. Its population served is well below the county average of 340 people per system, and accounts for less than 0.1% of the 117,512 people reported by systems filed under the county. Across Connecticut, the 2,363 active systems average 1,247 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Mayflower Inn 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. Connecticut has 483 active non-transient non-community water systems, 20% of the state's 2,363 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 2,263 Connecticut systems (96%) list groundwater as their primary source.
Who owns and regulates Mayflower Inn?
EPA lists Mayflower Inn as privately owned. The CT state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 297 of the 346 active systems in Litchfield County (86%) are also privately owned.
