How does Ringwood compare with other water systems in Major County?
By EPA's size categories, Ringwood is a very small system (500 people or fewer). Major County has 9 active public water systems, and Ringwood is the 3rd-largest of them by population served. Its population served is about 22% below the county average of 545 people per system, and accounts for 8.7% of the 4,901 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 Ringwood is well below that figure.
