MMWD posts new watering limits for Marin County

The new Water Rules for Marin County are as follows:

(For more information please visit

With reservoirs at historic lows, Marin Water's board of directors adopted new mandatory water use restrictions to help preserve our water supply. The goal of the mandatory restrictions is to achieve a 40 percent reduction in overall water use district-wide.

Water Use Restrictions

Education and Enforcement

The district is focused primarily on education to help the community reduce water use and will rely on customers to follow the rules.

We offer free water-saving fixtures including hose nozzles, faucet aerators and shower heads. Check your toilets for leaks with our leak detection dye tablets.

Email to request your fixtures and tablets. We also have rebates available to help offset the cost of high efficiency washing machines, smart irrigation controllers, gray water systems, and more.

Beginning May 1, not following the water use restrictions listed above will result in a written warning. The second violation will result in a $25 fine, and any subsequent violations will result in a $250 fine.


The district may grant exemptions or variances due to hardship, emergency conditions affecting health and safety, or to pursue an alternative means of compliance.

For more information, call 415.945.1520. To request a variance, email with a detailed explanation as to the reason(s) you are requesting a variance.
