The Germantown Water System is under a boil advisory.

System Operator Scott Day says the advisory is a precautionary due to upgrades being made to the system.

“We’re upgrading our Dogwood Trail facility,” he said. “We’re putting in boaster pumps, a constant pressure system and new piping, which will benefit customer’s on the system.”

Day said customers on the system should have received a letter outlining the advisory last week. He expects the advisory to be lifted next week.
