How does Darlington Township compare with other water systems in Beaver County?
By EPA's size categories, Darlington Township is a very small system (500 people or fewer). Beaver County has 83 active public water systems.

Across Pennsylvania, the 7,217 active systems average 1,741 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Darlington Township 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. Pennsylvania has 1,026 active non-transient non-community water systems, 14% of the state's 7,217 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 6,632 Pennsylvania systems (92%) list groundwater as their primary source.
Who owns and regulates Darlington Township?
EPA lists Darlington Township as owned by a local government. The PA state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 25 of the 83 active systems in Beaver County (30%) are also owned by a local government.
