Serrano Water District and We Rock describe water response tools, mutual aid and contingency supplies

Jerry Vielander, general manager of Serrano Water District, and Vicky Osborne, director of emergency management for Water Emergency Response Organization of Orange County (We Rock), told Villa Park residents that water agencies maintain mutual-aid arrangements, contingency equipment and plans to respond to breaks, sinkholes and regional incidents.

Vielander described routine water-main breaks as the kind of "little mini disasters" that keep agencies practiced and said operators keep parts, equipment and contact lists ready. Vicky Osborne, who coordinates mutual aid among 36 public potable water and wastewater agencies in Orange County, said the county’s water systems are interconnected and agencies can sometimes bypass damaged sections with temporary "jumpers" or interties.

Osborne and Vielander reviewed recent local incidents and response tools. Speakers showed video of a January sinkhole and water-main break in Orange that required a temporary bypass; Osborne said crews deployed a temporary hose/hydrant jumper and that the system was intertied to limit customer impacts. She said the county has 13 water trailers that can be filled and distributed at collection points, and that contracts exist to bring in bottled water if distribution is needed.

On water quality and recovery, Osborne described the testing and disinfection steps required when reservoirs or treatment systems are damaged: emptying, disinfecting, refilling and taking samples at many points. She said in prior responses agencies sampled dozens or more locations and that certain contaminants (Osborne cited benzene as an example common after fires) can force longer cleanup and sampling timelines. She gave operational details used during wildfire-related service impacts: boil-water notices, do-not-use notices, and the sequence of isolation, repair and testing before repopulation of service.

The presenters emphasized resident preparedness: store an emergency water supply (minimum 1 gallon per person per day, longer if possible), reduce nonessential indoor water use during shortages, and register for Alert OC for official water notices. Vielander urged residents to keep digital copies of important documents and personal media off-site; he said he keeps backups in the cloud and a ready bag for emergencies.

Osborne described ongoing countywide coordination: weekly general-manager briefings, mutual-aid resource lists, regional fuel planning for response vehicles, and outreach to the city and county emergency pages so customers can find official water notices during incidents.
