How does Chevron M11270 compare with other water systems in Midland County?
By EPA's size categories, Chevron M11270 is a very small system (500 people or fewer). Midland County has 57 active public water systems. Its population served is well below the county average of 3,029 people per system, and accounts for less than 0.1% of the 172,649 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 Chevron M11270 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.
