7. Meeting Sustainable Water Goals SOUTH METRO WATER SUPPLY AUTHORITY Planning Conservation Collaboration

8. Commitment to conservation Strive to meet new challenges

9. SMWSA GROUNDWATER WORKING GROUP Phase One: Received $104,500 from the Colorado Water Conservation Board to study the feasibility of a regional aquifer storage and recovery (ASR). Phase Two: Received $425,000 from the Colorado state revolving funds for the implementation of findings from feasibility study. Goal to increase knowledge of the aquifer’s ability to accept ASR for the storage of future water supplies.
