How does Sti Group compare with other water systems in Orange County?
By EPA's size categories, Sti Group is a very small system (500 people or fewer). Orange County has 41 active public water systems. Its population served is well below the county average of 1,898 people per system, and accounts for less than 0.1% of the 77,799 people reported by systems filed under the county. Across Texas, the 7,078 active systems average 4,789 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Sti Group 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. Texas has 862 active non-transient non-community water systems, 12% of the state's 7,078 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 5,215 Texas systems (74%) list groundwater as their primary source.
Who owns and regulates Sti Group?
EPA lists Sti Group as privately owned. The TX state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 30 of the 41 active systems in Orange County (73%) are also privately owned.
