Residents of a Mississippi town, along with a portion of the largest state university, remain under a boil-water advisory after flooded caused major water main breaks over the weekend.

Oxford Water System customers will need to continue taking precautions with their tap water for a couple more days. The boil-water notice that was put into affect on Saturday remains in affect through at least Wednesday, according to Mayor Robyn Tannehill.

Several water mains broke over the weekend due to the large amount of heavy rainfall Oxford received last week. The first break was discovered early Saturday morning near the Max Hipp Industrial Park, prompting the city to initiate the notice. A second break was found behind the Urgent Care center off Highway 7 on Sunday morning.

By Sunday afternoon water pressure returned to most parts of Oxford and water samples were sent to the Mississippi Department of Health on Monday.

Tannehill provided an update through her Facebook page on Sunday afternoon.

“We are scheduled to deliver the samples to the Mississippi Department of Health (Monday) morning at 10 am. Results typically take 48 hours,” Tannehill’s post read. “We are probably looking at Wednesday before the Boil Water Notice is removed.”

Portions of Ole Miss’ campus are also affected by the city’s notice. The Gertrude C. Ford Center, Rowan Oak, University Museum, South Oxford Center, Carriage House, Memory House, Walton-Young House, Jackson Avenue Center, Music Building and the Grisham House are all adhering to the boil-water notice until it is lifted by the city.
