How does Century Tool compare with other water systems in Hennepin County?
By EPA's size categories, Century Tool is a very small system (500 people or fewer). Hennepin County has 198 active public water systems. Its population served is well below the county average of 6,444 people per system, and accounts for less than 0.1% of the 1,275,854 people reported by systems filed under the county. Across Minnesota, the 6,465 active systems average 820 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Century Tool 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. Minnesota has 470 active non-transient non-community water systems, 7.3% of the state's 6,465 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 6,261 Minnesota systems (97%) list groundwater as their primary source.
Who owns and regulates Century Tool?
EPA lists Century Tool as privately owned. The MN state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 112 of the 198 active systems in Hennepin County (57%) are also privately owned.
