How does Duit Construction compare with other water systems in Oklahoma County?
By EPA's size categories, Duit Construction is a very small system (500 people or fewer). Oklahoma County has 113 active public water systems. Its population served is well below the county average of 7,828 people per system, and accounts for less than 0.1% of the 884,508 people reported by systems filed under the county. Across Oklahoma, the 1,254 active systems average 2,907 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Duit Construction 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. Oklahoma has 84 active non-transient non-community water systems, 6.7% of the state's 1,254 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 701 Oklahoma systems (56%) list groundwater as their primary source.
Who owns and regulates Duit Construction?
EPA lists Duit Construction as privately owned. The OK state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 93 of the 113 active systems in Oklahoma County (82%) are also privately owned.
