Hetch Hetchy water supply to Hayward fully restored

The City of Hayward Utility Division successfully shifted Hayward back onto water supplied by San Francisco's regional Hetch Hetchy water system on Sunday after an unscheduled disruption on Friday.

The disruption-which stemmed from maintenance work being conducted on the regional Hetch Hetchy system by the San Francisco Public Utilities Commission-necessitated a temporary switch to water supplied by the East Bay Municipal Utility District (EBMUD).

The temporary switch from Hetch Hetchy water flowing to Hayward from the south to EBMUD supply from the north impacted service to some Hayward water customers but posed no health or public safety concerns.

Specifically, the opening and closing of valves and supply lines to make the initial switch stirred up sediment in water lines that may have resulted in temporary water discoloration and the change in directional flow of water supply from south to north affected water pressure for a small number of customers.

Hayward water utility infrastructure that ties the City into both the regional Hetch Hetchy system and EBMUD and allows Hayward to be served by both systems is a valuable feature of the City's water system and helps ensure continued water supply in an emergency.
