Quality, Supply, & Storage Levels

Water Quality & Supply

The Consolidated Mutual Water Company is pleased to present a summary of the water provided to customers during the past year.

Two independent and separate water treatment systems supply water to our customers:

  • Denver Water Treatment facilities supply approximately 60 percent of Consolidated’s service area.
  • Consolidated’s Maple Grove Treatment Plant supplies the remaining 40 percent of our customers.

Both systems provide high-quality drinking water and meet or exceed all requirements of the Safe Drinking Water Act.  All treatment plants are operated by certified class “A” operators as required by EPA regulations.

Click on the buttons to the right for a summary of water quality for each system along with details about where your water comes from, what it contains and how it compares to standards set by regulatory agencies.  Certified laboratories complete all reportable water analysis to ensure compliance with all regulations.
