SFPUC Blend Change Notice (UPDATE)

UPDATE 12/08/16 @ 1:15 p.m.

SFPUC’s lab analysis and sampling indicate the likely source of the taste and odor causing compounds is the San Antonio Reservoir. After reviewing system-wide operational needs, the SFPUC will suspend water supplies from this source later today. After this change, water supplies for the service areas will be provided by Hetch Hetchy and Harry Tracy Water Treatment Plant.

These actions should collectively improve taste and odor in all areas, including the MPWD service territory.


UPDATE 12/08/16 @ 12:30 p.m.

The SFPUC (San Francisco Public Utilities Commission) is aware that customers in San Francisco and throughout the wholesale territory, including the Mid-Peninsula Water District (MPWD), are still reporting taste and odor issues with the tap water. Last week, as part of normal operations, the SFPUC reduced supply from one part of the regional water system and increased supply from another. This operation can disturb naturally occurring sediment in reservoirs and pipelines, which can affect taste. The SFPUC continues to proactively test parts of its system to locate the source of these issues and resolve them as soon as possible. Their main priority is to address these concerns.

As a resource, the SFPUC’s website contains updates

The SFPUC is hosting a press conference this afternoon at 2:30 p.m. to further discuss the matter. Information will be posted to its website.

The MPWD appreciates your understanding and patience. The water is safe to drink and continues to meet all drinking water standards. Please contact us with any questions or concerns.


NOTICE 12/05/16

Due to water supply management by the San Francisco Public Utilities Commission, the Hetch Hetchy water supply has been reduced and is being blended with other regional water system sources, which supplies the MPWD system. The water meets all quality standards and is safe to drink. Please contact the MPWD with any concerns.
