New Disinfection as of February 2004

In February of 2004, our water supplier, San Francisco Public Utilities Comission (SFPUC), converted from chlorine to chloramine as their water disinfectant. Chloramine is the combination of chlorine and ammonia. The conversion to chloramine has allowed SFPUC and Mid-Peninsula Water District to increase protection of public health, while meeting stricter state and federal water quality regulations, lowering risk of bacterial contamination, and improving taste and odor.

Mixing System Installed In Storage Tanks

Because of the chloramine disinfection process that has gone into effect, early 2004, it is important more than ever for the water district to prevent the water from becoming stagnant for too long a period of time. In an effort to keep the water moving inside of our reservoirs, we have installed mixing systems and sampling stations in 7 of 10 storage tanks. These mixing systems will play a vital role in the effort to continue serving our customers the purest water possible.


Water Fluoridation Effective November 2005

A somewhat controversial subject with many of our customers has finally been decided for all of us by the San Francisco Public Utilities Commission. On February 16th, 2001, the San Francisco Public Utilities Commission adopted their staffs recommendation to construct new fluoridation facilities at the San Antonio Pump Station, referred to as the "East Bay Alternative." Engineering studies estimated that this new facility would cost less than upgrading the existing facilities at the Polhemus plant located on Polhemus Drive between Anza Blvd. and Crystal Springs Road. For the first time, this facility would provide fluoridated water to the 19 Bay Area water agencies that presently do not receive fluoridated water. This, of course, includes our Mid-Peninsula Water District. The new fluoride facilities has been completed and operational since November 2005.
