Leaders in Water Stewardship

South Metro Water Supply Authority is a partnership of 14 water providers in the South Metro Region of Denver.

These providers joined forces in 2004 out of the need to shift the region away from reliance on non-renewable underground water supply and toward supplies that replenish with every year’s snowmelt. Rather than doing so on their own, however, they knew that by coming together and partnering on projects and initiatives, they would be more effective and their customers would benefit from greater efficiencies and economies of scale.

our focus is water supply
