Conservation & Education

Water is a precious and scarce commodity, and South Metro Water Supply Authority and its members are leaders in developing innovative and effective approaches to conserve and use water efficiently.

The South Metro Region is a leader in water conservation

We have reduced per capita water demand by over 30% in recent years. Because our members are committed to conservation and water efficiency, water users have reduced water use to less than 120 gallons per capita per day (gpcd), already surpassing the goal for 2050 set for our region in the Colorado Water Plan of 129 gpcd.

Graphic showing reduction of water demand per person from 215 gallons per day in 2015 to 146 gallons per day in 2010 to 120 gallons per day in 2019. Our 2050 goal of 129 gallons per day per capita water demand is already exceeeded.
