Third Drinking Water Intake at Lake Mead

Intake 3

More than 1,000 concrete truck loads
were transported to the intake site on 143
barge trips.

In order to address unprecedented drought conditions and provide long-term protection of Southern Nevada's primary water storage reservoir—Lake Mead— the Southern Nevada Water Authority constructed a third drinking water intake capable of drawing upon Colorado River water at lake elevations below 1,000 feet (above sea level).

The third intake ensures system capacity if lake levels fall low enough to render SNWA's existing intake system inoperable. It also will protect municipal water customers from water quality issues associated with declining lake levels.

Intake No. 3 began conveying water to SNWA's water treatment facilities in September 2015.

The construction of Intake No. 3 began in 2008 and was an enormous project involving a tunnel boring machine chewing through solid rock underneath Lake Mead and an intake structure two and a half miles offshore. More than 1,000 concrete truck loads were transported to the intake site on 143 barge trips.

Preparations are now under way to complete construction on a low lake level pumping station, which will further protect Southern Nevada's access to its primary water supply in Lake Mead.
