How does Gateway Development compare with other water systems in Johnson County?
By EPA's size categories, Gateway Development is a very small system (500 people or fewer). Johnson County has 125 active public water systems. Its population served is well below the county average of 1,384 people per system, and accounts for 0.2% of the 172,955 people reported by systems filed under the county. Across Iowa, the 1,828 active systems average 1,718 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Gateway Development is roughly in line with 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. Iowa has 118 active non-transient non-community water systems, 6.5% of the state's 1,828 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 1,502 Iowa systems (82%) list groundwater as their primary source.
Who owns and regulates Gateway Development?
EPA lists Gateway Development as privately owned. The IA state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 102 of the 125 active systems in Johnson County (82%) are also privately owned.
