LAS VEGAS (AP) - Completion of an $817 million tunnel for the so-called "third straw" drinking water intake from Lake Mead to Las Vegas has been pushed back another 13 months.
The Southern Nevada Water Authority board on Thursday set a July 2015 date, but didn't allocate additional money for the job.
The three-mile tunnel project began in 2008. A March 2011 completion date was previously revised to May 2014.
Authority chief Pat Mulroy says contractor Vegas Tunnel Constructors will use $13 million in contingency funds.
The Las Vegas Review-Journal reports the board also approved idling one of two existing water intakes until March, so that workers can connect it to an existing pumping station.
Las Vegas draws about 90 percent of its drinking water from the Colorado River reservoir behind Hoover Dam.
