The Evansville Water Utility has issued what it is calling a precautionary water advisory (this is not a boil advisory) for the East Side of Evansville. Utility officials say all of Evansville's East side area, especially higher elevations, may experience water pressure problems due to an unidentified issue that is being investigated. They say additional information will be released as soon as they determine the cause of the problem. In the meantime, they say it is advisable to boil your water as a precaution.
