The Phoenix City Council has approved three measures aimed at better securing drinking water resources for the future.

The council voted unanimously Tuesday to form a partnership with Tucson water providers that would allow for storage and recovery of Central Arizona Project water between the two regions.

The council also opted to remain engaged in continuing discussions about water shortages on the Colorado River. As the largest municipal user of CAP water, the city has a large stake in the future of the Colorado River.

The city will also encourage a review of Arizona's groundwater laws to ensure development is sustainable over the long term.

Mayor Greg Stanton said the possibility of climate change altering Arizona's future water supply means the city must do more to look ahead and innovate.
