How does Comcast Cablevision compare with other water systems in New London County?
By EPA's size categories, Comcast Cablevision is a very small system (500 people or fewer). New London County has 394 active public water systems. Its population served is well below the county average of 532 people per system, and accounts for less than 0.1% of the 209,444 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 Comcast Cablevision 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 Comcast Cablevision?
EPA lists Comcast Cablevision 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. 320 of the 394 active systems in New London County (81%) are also privately owned.
