Used to supply public drinking water, Source Water is untreated water from streams, rivers, lakes, or underground aquifers.  The source of drinking water for many Tahoe Basin communities, including Incline Village and Crystal Bay, is Lake Tahoe. The water is pumped out the lake, managed in a water treatment facility, and delivered to customers.

Source Water Protection is protecting sources of drinking water from contaminates that are harmful to human health. The water in Lake Tahoe is of excellent quality, and treatment plants are designed to remove or inactivate microorganisms. However, emerging contaminates and increases in contaminate quantities often require new and expensive treatment upgrades and increase the threat of waterborne illness.

Everyone can help protect the quality of our drinking water through simple sanitary practices.
