A Review of the Marin Municipal Water District’s Alternatives to Improve Water Supply Reliability

The Marin Municipal Water District (MMWD) is developing a new program to improve water supply reliability. MMWD staff has identified a theoretical water supply deficit of 6,700 afy by the year 2025. A range of alternatives are being considered to address the projected supply deficit. The alternatives include increased water conservation, improved reservoir management, increased water recycling, importing additional Russian River water and constructing a desalination facility.

Through numerous mechanisms, MMWD customers have voiced a strong and consistent preference for the most environmentally friendly solution to improved water supply reliability. Improved water conservation programs combined with an improved distribution system and reservoir management along with a modest increase in water recycling can provide a long-term solution to improving water supply reliability. This can be done at much lower cost compared to a desalination facility and is the most environmentally friendly solution.
