2017 Proposed Rate Increase

Why are water rates increasing?

I use less water, why do I pay more for water?


While you will see a small increase in your bill, you’re not just paying more for water, you’re paying for the service. Our customers pay to operate the Mt. Tam Watershed, 7 reservoirs, 3 treatment plants and water processing, the entire delivery system, which includes 900 miles of underground pipelines, 125 storage tanks, and 95 pump stations to deliver high-quality, locally sourced water 24/7, 365 days per year for a penny per gallon.

What do the increases pay for?

The additional $10.1 million collected over the next two years will help pay for infrastructure improvements, such as: treatment plant seismic retrofits (watch this video to learn more), replacing 8 miles of aging pipeline, replacing water storage tanks to ensure seismic stability, upgrading electronic control and communication systems used to control and monitor the treatment, production and distribution of water, and repairing roads, restoring trails and enhancing winter habitat for endangered fish. 

How much increase are we talking about?


For the average residential customer with a 5/8 inch meter and using approximately 6,358 gallons per month (8.5 CCFs), the proposed monthly increase would be approximately $2.90 or 5% effective July 1, 2017 and $4.09 or 7% effective July 1, 2018. Even with the increase, your water still costs a penny per gallon.

Where does my water come from?


The Mt. Tamalpais Watershed - the crown jewel of Marin County - is the primary source of drinking water for our customers. It is a place of unparalleled scenic beauty, home to rare and endangered species, and a popular recreational destination. 
Maintaining 21,600 acres of the Mt. Tamalpais Watershed without the use of herbicides has a cost. MMWD’s responsibilities include managing wildfire risks, restoring habitat, protecting rare plants and animals, maintaining access roads and trails, assisting visitors, and preserving the ecological health of the creeks.


Why reinvest now?


It is critically important that the District continually re-invest in the $598 million assets it holds and keep pace with inflation and other cost increases. Each year the District evaluates its infrastructure needs, programs, and operations and maintenance costs for the ensuing fiscal year. As the oldest municipal water district in California, we face significant, and costly, challenges in maintaining and replacing aging infrastructure.

How can I participate?
