From The Nevada Independent (Daniel Rothberg):

The Southern Nevada Water Authority has expressed interest in helping finance a wastewater reuse project being pursued by Southern California’s municipal wholesale water provider.

The goal: To free up Colorado River water.

The concept looks something like this. If the Metropolitan Water District of Southern California (MWD) could recycle a portion of its water, it could reduce its overall consumption of Colorado River water stored at Lake Mead. In turn, the water authority would help fund the project in exchange for additional water that MWD would be able to leave in the reservoir because of it.

Such a project is in the early stages, and it could take at least a decade to build out. Still, the water authority and MWD are actively discussing a potential partnership. John Entsminger, the water authority’s general manager, said he hoped there would be a preliminary deal next spring…

If the project moves forward, it would cost about $3.4 billion, recycling water for about $1,800 per acre-foot, Hasencamp said. It has not yet been determined what Nevada’s financial contribution would be. The project would still need to be approved by both the water district’s full board the MWD board.

The project is similar to other water-swapping proposals. Minute 323, a binational agreement between the United States and Mexico, tasked a working group with studying desalination plants. New supplies would allow Colorado River users to more easily exchange water at Lake Mead.
