Water Banking

Like a savings account, groundwater banking provides SNWA the ability to store water for future use.

In years when Nevada’s Colorado River allocation exceeds the valley’s water demands, SNWA stores water in the Las Vegas Valley Groundwater Basin as a reserve. But SNWA also has water banking agreements with Arizona and California.
