The Phoenix City Council voted against a plan to raise water rates Wednesday. 

The vote was 5-3 Wednesday afternoon to not raise rates by 6 percent each of the next two years.

The proposed increase is needed to build infrastructure for alternative water supplies to deal with the Colorado River shortage. Experts say the increase, and the work it would fund, could be key for the city's future.
