How does Woodcastle compare with other water systems in Linn County?

By EPA's size categories, Woodcastle is a very small system (500 people or fewer). Linn County has 161 active public water systems. Its population served is well below the county average of 769 people per system, and accounts for less than 0.1% of the 123,772 people reported by systems filed under the county. Across Oregon, the 2,536 active systems average 1,587 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Woodcastle 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. Oregon has 346 active non-transient non-community water systems, 14% of the state's 2,536 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 2,175 Oregon systems (86%) list groundwater as their primary source.

Who owns and regulates Woodcastle?

EPA lists Woodcastle as privately owned. The OR state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 99 of the 161 active systems in Linn County (61%) are also privately owned.
