Starting at midnight Tuesday, the city of Washington will be under a three day boil order. City officials say the boil order is a precaution, as there will be a planned maintenance project at the city's water treatment plant plant number two. They add that the city will notify the public of any changes, or lifting of the boil order. During the boil order, city water users should first boil tap water for five minutes before drinking or using to prepare food. Bottled water could be used as an alternative to boiling. Tap water may be used for bathing, showering, and household cleaning. Household dishwashers are generally safe to use if the water reaches a final rinse temperature of at least 150 degrees or if the dishwasher has a sanitizing cycle. The city has taken steps to minimize the impact of the boil order and provide advance notice to affected residents and businesses. This boil order does not apply to city residents or businesses that obtain their water from the Northern Tazewell Public Water District or Sundale Utilities, otherwise known as Washington Estates.
