How does 13 Mile Center compare with other water systems in Williams County?
By EPA's size categories, 13 Mile Center is a very small system (500 people or fewer). Williams County has 19 active public water systems. Its population served is well below the county average of 1,990 people per system, and accounts for 0.1% of the 37,806 people reported by systems filed under the county. Across North Dakota, the 403 active systems average 1,864 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so 13 Mile Center 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. North Dakota has 5 active non-transient non-community water systems, 1.2% of the state's 403 active systems. Purchased surface water means the system buys surface water from another public water system rather than drawing its own. 83 North Dakota systems (21%) list purchased surface water as their primary source.
Who owns and regulates 13 Mile Center?
EPA lists 13 Mile Center as privately owned. The ND state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 10 of the 19 active systems in Williams County (53%) are also privately owned.
