Recycled Water

Water is too valuable to be used just once. Recycled water is a drought-proof source of water that offers multiple benefits. Using recycled water extends our drinking water supplies, reduces the need for additional potable water facilities, reduces the amount of treated wastewater released into the ocean, reduces our reliance on imported water supplies and increases our water supply reliability. The use of recycled water is a key component of MMWD’s conservation and water use efficiency programs as every gallon of recycled water used results in a gallon of drinking water that can be saved for potable uses.

Since the early 1980s, we have pioneered the use of recycled water for non-agricultural purposes in northern California. Up to two million gallons a day are safely recycled and distributed in a separate pipeline system to more than 350 customers in northern San Rafael. Recycled water is used for irrigation, toilet flushing and other non-drinking purposes. MMWD was the first water supplier in California to use recycled water for car washes, air-conditioning cooling towers, commercial laundries and toilet flushing in a condominium complex.

To produce recycled water, we take wastewater treated by our partners at the Las Gallinas Valley Sanitary District in San Rafael and further treat it in our Las Gallinas Valley Water Recycling Facility to meet stringent water quality and safety requirements set by the California Department of Public Health. Our recycled water is crystal clear, odorless and free of harmful bacteria. It is similar in quality to swimming pool water.
