How does Simplot Feeders Ltd compare with other water systems in Walla Walla County?

By EPA's size categories, Simplot Feeders Ltd is a very small system (500 people or fewer). Walla Walla County has 69 active public water systems. Its population served is well below the county average of 1,126 people per system, and accounts for less than 0.1% of the 77,717 people reported by systems filed under the county. Across Washington, the 4,705 active systems average 2,172 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Simplot Feeders Ltd 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. Washington has 400 active non-transient non-community water systems, 8.5% of the state's 4,705 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 4,370 Washington systems (93%) list groundwater as their primary source.

EPA lists Simplot Feeders Ltd as privately owned. The WA state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 43 of the 69 active systems in Walla Walla County (62%) are also privately owned.
