How does Hertrich compare with other water systems in Kent County?

By EPA's size categories, Hertrich is a very small system (500 people or fewer). Kent County has 136 active public water systems. Its population served is well below the county average of 1,201 people per system, and accounts for less than 0.1% of the 163,362 people reported by systems filed under the county. Across Delaware, the 494 active systems average 2,238 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Hertrich 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. Delaware has 82 active non-transient non-community water systems, 17% of the state's 494 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 459 Delaware systems (93%) list groundwater as their primary source.
