A vehicle hit a fire hydrant in Franklin early Friday morning, causing a massive boil water order for the western half of the city through part of today.

Anyone in a home or business west of U.S. 31 was told to vigorously boil their water for at least one full minute due to a water main break.

About 2,700 homes and businesses are affected, including three Franklin schools, Indiana American Water operations superintendent Ron Ballard said.

Indiana American Water fixed the problem, caused when a hydrant was hit, but warned residents and workers that the water could be contaminated with bacteria, according to a news release.

The homes and businesses affected are on the west side of U.S. 31, from Commerce Drive to the Franklin Lakes neighborhood, Ballard said.

Franklin Community High School, Custer Baker Intermediate School and Creekside Elementary stayed open Friday and students and staff were given bottled water, superintendent David Clendening said.

The boil water order is expected to expire by noon today, but customers will be alerted with a phone call, Ballard said.
