Common questions
Who is my water provider in Johnstown, Colorado?
Johnstown, Colorado is served by 2 community water systems, not one: Town of Johnstown, Little Thompson Water District. Which one serves a given house depends on the address.
Why does Johnstown have more than one water provider?
Service areas follow districts and annexations, not town limits, so a town is often split between several systems, and a wholesaler's area can overlay the retail system that buys from it. The address lookup on this page settles which one covers a given point.
