How does Britton compare with other water systems in Marshall County?

Its population served is about 4 times the county average of 305 people per system, and accounts for 57% of the 2,134 people reported by systems filed under the county. Across South Dakota, the 699 active systems average 1,387 people each. Nationally, the average active community water system reports serving 6,703 people, so Britton is well below that figure.

What does “community water system” mean?

Purchased groundwater means the system buys groundwater from another public water system rather than drawing its own. 100 South Dakota systems (14%) list purchased groundwater as their primary source.
