Where Does Your Water Come From

Depending on local geology, the availability of groundwater varies tremendously within the Three Valleys area. Thus, the water delivered to your home or business may consist of some quantity of locally occurring groundwater, combined with imported MWD water purchased by Three Valleys for the cities, retail water companies or districts that serve you directly. On average, Three Valleys meets about 60 percent of the region's needs, amounting to over 22 billion gallons of high quality water each year. Recycled water is a small but important part of the water supply, used for irrigation and industrial uses.

To stay ahead of the changing water supply and water quality picture, the role played by Three Valleys Municipal Water District has grown in responsibility and complexity. Well positioned to identify region-wide challenges and opportunities, the district now facilitates inter-agency water planning, local exchanges and transfers, water conservation, and other projects to manage all available supplies as efficiently and economically as possible.
