November 30, 2019: The California State Department of Public Health issued a Boil Water Advisory for the City of Poway.  

December 6, 2019 - 6PM: The State Water Resource Control Board has lifted the Boil Water Advisory.

Below is a summary of the cleaning and disinfecting procedures that must be followed, before you can safely self-re-open your food facility.

These procedures include:

1)    Run all faucets for 3 to 5 minutes to flush the lines with safe water before use.  Include faucets located in restrooms, throughout the kitchen, waiter stations and drinking fountains.

2)    Flush lines and sanitize all ice machines.  All ice must be disposed of, additional details on how to properly disinfect the ice machine are included in the disinfection procedures.

3)    Flush lines and sanitize coffee machines, post-mix machines and fountain machines.

4)    Clean and sanitize all fixtures, sinks and equipment connected to water supply lines.

5)    Follow the manufacturer’s recommended procedures for disinfecting water softeners, prior to putting them back online; disinfecting filters or replacing media in small filters on ice machines, water treatment systems, beverage vending machines; and replacing carbon filters or carbon media in filters.

6)    Rewash and sanitize all dishes, multi-use utensils and work areas. 

After completing these procedures, food facilities may self-open.  If operating under a Modified Health Permit, the Modified Health Permit can be removed and discarded.
