DURANGO CITY OF is one of 87 community water systems in Colorado in the 10,001 to 100,000 people size category, serving 33,787 people from surface water.

The record involves the Surface Water Treatment Rules, the Stage 2 Disinfectants and Disinfection Byproducts Rule, and the Total Coliform Rules.
