How does Delta Company Group compare with other water systems in Harris County?

By EPA's size categories, Delta Company Group is a very small system (500 people or fewer). Harris County has 1,246 active public water systems. Its population served is well below the county average of 4,849 people per system, and accounts for less than 0.1% of the 6,041,784 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 Delta Company 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. Purchased groundwater means the system buys groundwater from another public water system rather than drawing its own. 302 Texas systems (4.3%) list purchased groundwater as their primary source.

Who owns and regulates Delta Company Group?

EPA lists Delta Company 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. 732 of the 1,246 active systems in Harris County (59%) are also privately owned.
