The city of Napa has ordered residents of the Silverado Highlands area to boil their tap water after the destruction of a pump station and the shutdown of the Milliken treatment plant.
The boil-water requirement, which Napa announced Monday night on its Facebook page, covers areas of Silverado Resort and Spa, Monticello Park and Vichy Avenue.
Hillcrest pump station was destroyed in the 25,000-acre blaze that overtook Atlas Peak to the city’s east, city Water Manager Joy Eldredge announced earlier Monday. The Milliken water treatment facility was also left inoperable, the city said in its Facebook statement.
Water customers on the following roads are asked either to boil their tap water or use bottled water for drinking and cooking:
- Hagen Road
- Woodland Drive
- Syar Drive
- Holly Court
- Old Coach Road
- Any areas north of Hagen Road and east of the Silverado Trail
The city announced it has set up temporary pumps to restore pressure in the upper Silverado area, and will perform water testing and inform customers when the boil-water notice is lifted.
Customers are advised to bring all tap water to a boil, let it boil for one minute, and let it cool before using. Boiled or bottled water should be used for drinking and food preparation until further notice. Boiling kills bacteria and other harmful organisms in the water.
An alternative method of disinfection for residents that are not able to boil their water is to use fresh, unscented, liquid household bleach. To do so, add 8 drops (or 1/8 teaspoon) of bleach per gallon of clear water or 16 drops (or 1/4 teaspoon) per gallon of cloudy water, mix thoroughly, and allow it to stand for 30 minutes before using. A chlorine-like taste and odor will result from this disinfection procedure and is an indication that adequate disinfection has taken place.
Water disinfection tablets may also be used by following the manufacturer’s instructions.
The city Water Division anticipates resolving the problem within four days, Napa announced.
