How does Ravia compare with other water systems in Johnston County?
By EPA's size categories, Ravia is a very small system (500 people or fewer). Johnston County has 13 active public water systems, and Ravia is the 6th-largest of them by population served. Its population served is about 42% below the county average of 792 people per system, and accounts for 4.5% of the 10,296 people reported by systems filed under the county. Across Oklahoma, the 1,254 active systems average 2,907 people each. Nationally, the average active community water system reports serving 6,703 people, so Ravia is well below that figure.

Groundwater means the system draws its water from wells or springs fed by underground aquifers. 701 Oklahoma systems (56%) list groundwater as their primary source.
