Foster City officials have received confirmation through the Bay Area Water Supply and Conservation Agency (BAWSCA) that the Hetch Hetchy water system, owned and operated by the San Francisco Public Utilities Commission (SFPUC), remains secure despite the proximity of the reservoir to the Rim Fire, currently blazing in and around Yosemite National Park.

Foster City purchases 100% of its water supply from the SFPUC, which uses the Hetch Hetchy system to store and supply its water. The SFPUC has assured all of the agencies that purchase water from it that there are no changes or impact to water quality or delivery from the Hetch Hetchy Reservoir due to the effects of the Rim Fire or the efforts to control the fire. Due to the rocky, granite terrain and limited brush along the perimeter of the reservoir, there is little risk for direct impacts on the reservoir. Some ash has fallen onto the surface of the reservoir, but there has been no impact to the quality of the drinking water, which is being withdrawn from the reservoir at a depth of 260 feet.

Officials continue to closely monitor both the reliability and quality of the water on an ongoing basis and will alert consumers if any precautions should be taken in the future.
