    Staff Directory

Annual water system flushing is performed at the beginning of each year to remove trace minerals, mostly iron and manganese from the water mains. Although iron and manganese do not pose health concerns, they can create aesthetic issues affecting the taste, clarity, and color of the water. This sediment is removed, and water quality maintained by unidirectional flushing of the water mains on an annual basis. Unidirectional water main flushing involves valving off each section of water main and then directing water at high flow rates through fire hydrants.
