How does Creekside Development compare with other water systems in Oregon?
By EPA's size categories, Creekside Development is a small system (501 to 3,300 people). 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 Creekside Development is about 7.3 times 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. Surface water means the system draws its water from rivers, lakes, streams or reservoirs. 211 Oregon systems (8.3%) list surface water as their primary source.
Who owns and regulates Creekside Development?
EPA lists Creekside Development as Native American-owned. The EPA Region 10 is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act.
