Welcome to the Tahoe Water Suppliers Association (TWSA) webpage!
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 the protection of drinking water sources 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 contaminants and increases in contaminants quantities often increases the threat of waterborne illness and creates requirements for new and expensive treatment upgrades.
Everyone can help protect the quality of our drinking water through simple sanitary practices.
