How does Heidelberg Materials compare with other water systems in Allen County?
By EPA's size categories, Heidelberg Materials is a very small system (500 people or fewer). Allen County has 87 active public water systems. Its population served is well below the county average of 3,719 people per system, and accounts for less than 0.1% of the 323,592 people reported by systems filed under the county. Across Indiana, the 3,969 active systems average 1,456 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Heidelberg Materials 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. Indiana has 603 active non-transient non-community water systems, 15% of the state's 3,969 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 3,769 Indiana systems (95%) list groundwater as their primary source.
Who owns and regulates Heidelberg Materials?
EPA lists Heidelberg Materials as privately owned. The IN state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 74 of the 87 active systems in Allen County (85%) are also privately owned.
