How does Minnesota Pipeline compare with other water systems in Delta County?
By EPA's size categories, Minnesota Pipeline is a very small system (500 people or fewer). Delta County has 42 active public water systems. Its population served is well below the county average of 660 people per system, and accounts for 0.3% of the 27,718 people reported by systems filed under the county. Across Colorado, the 2,207 active systems average 3,400 people each. Nationally, the average active community water system reports serving 6,703 people, so Minnesota Pipeline is well below that figure.
What does “community water system” mean?
A community water system serves at least 15 connections used by year-round residents, or regularly serves at least 25 year-round residents. Homes, apartments and mobile-home parks are served by these. Colorado has 1,068 active community water systems, 48% of the state's 2,207 active systems. Purchased surface water means the system buys surface water from another public water system rather than drawing its own. 337 Colorado systems (15%) list purchased surface water as their primary source.
Who owns and regulates Minnesota Pipeline?
EPA lists Minnesota Pipeline as owned by a local government. The CO state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 10 of the 42 active systems in Delta County (24%) are also owned by a local government.
