Swanzy Reservoir

Swanzy Reservoir Issue

The City of Vallejo is experienced an issue with the Swanzy Reservoir, which resulted in sediment being carried into the water lines and pushed out into part of the system. The greatest area affected was South Vallejo, where approximately 1000 households and businesses were impacted.

The City took several samples of water throughout the day to ensure the water remained safe to drink.  Results meet all state water quality standards.

City crews were dispatched immediately to to isolate the reservoir, minimize impact on households, pump water from other facilities and flush the system to eliminate sediment in the pipes.  The area was flushed by 2:00 p.m. on February 11, 2018.   Residents were advised to run cold water for 5 to 10 minutes to pass through any remaining sediment, and to contact the Water Department if sediment was consistently present longer than 5 minutes.  Some residents and businesses may have also experienced low water pressure or air in their lines which occurs while the main water service is switched within the system.  The event has concluded, and City crews are investigating the faulty reading.  While the Swanzy Reservoir is offline, residents and households will receive water directly from the City's Flemming Hill Treatment Plant.

Swanzy is located in south Vallejo, in the hills of the popular neighborhood Glen Cove near the I-80 "Al Zampa Bridge" Bridge. It is one of the oldest reservoirs in the City dating back to the early 1900s.

The City appreciates the patience of those residents impacted and the quick
response by City crews to locate, isolate and address the issue.
