Poway residents were advised Saturday to boil their tap water before drinking or using it for cooking as crews scrambled to address possible contamination from recent heavy rain.
The San Diego County Department of Environmental Health separately ordered all restaurants and food facilities in Poway to close until the issue is resolved.
“We are taking all of the necessary steps to address this situation,” said City Manager Chris Hazeltine in a statement on the city’s website. “Restoring normal water service is our top priority.”
Crews were working around the clock to restore normal water service to the city of 50,000.
It is the first boil water advisory issued by the city since its incorporation in 1980.
Poway residents first reported discolored tap water on Friday. Testing showed the water to be safe, but the discoloration appeared to be citywide, so officials notified the State Water Resources Control Board and issued the boil water advisory around 6 p.m. Saturday.
The city said boiling water for one minute is sufficient to kill any harmful bacteria or other organisms.
Bottled water was to be available for residents at Lake Poway beginning at 7 a.m. on Sunday.
