CALDWELL, Idaho — The City of Caldwell on Tuesday terminated its boil advisory for drinking water that was issued following a loss of water pressure Monday night in mainlines serving multiple neighborhoods. 

On Tuesday afternoon, the City of Caldwell's Water Department deemed the water is safe to drink, and said "we appreciate the public's patience and apologize for the necessary inconvenience."

The impacted neighborhoods were located between Florida and Indiana avenues from Beech Street to Ustick Road. The order called for tap water in the subdivisions to be boiled before drinking.

As a precaution, residents were asked to boil tap water for three minutes before drinking or use bottled water.

According to the Caldwell Water Department, city crews closed water valves Monday as part of a scheduled outage. However, additional valves were unexpectedly found to be closed so that the planned valve closures led to a loss of water pressure in the mainlines supplying the areas listed earlier in this article. The pressure loss was discovered and resolved over a period of about two hours.

In its termination notice, the City of Caldwell said samples confirmed there was no contamination in the tap water, but officials issued the advisory "out of an abundance of caution."

A mainline pressure drop has the potential to create an unsafe drinking water condition. Low pressures pose the risk of drawing in bacteria or other contaminants from household water-supply plumbing or other connected water-system elements through backflow.

UPDATE: TERMINATION OF BOIL WATER ORDER. Test results confirm that the water is safe to drink. Samples taken yesterday...
