More than 22 billion gallons of water were lost in the last fiscal year as Houston contended with thousands of cases of broken and leaking municipal pipes.

The water loss amounts to about 15 percent of the city's water supply. A city spokeswoman, Jessica Michan said "the city is seeking $71 million from the state to rebuild 130 miles of pipe," according to local reports.

Houston spent $54 million last year to fix leaky pipes but that money reconstructed only 1 percent of water lines. Another $31 million was spent patching leaks. The city recorded about 11,300 leaks last fiscal year.

Other Texas cities seeing double-digit losses in their water supply are Dallas at 17.6 percent, San Antonio at 16 percent and Lubbock at 12 percent. Austin has cut its loss to under 8.5 percent.
