MERRILLVILLE | Halloween wasn't a treat for some Merrillville residents near 75th Place and Broadway.
A water main break Thursday morning left some residents in that area without water service for several hours and flooded some homes, said Joe Loughmiller, an Indiana American Water spokesman.
Loughmiller said "a lot of water" was released when the 16-inch line broke.
Town Manager Bruce Spires said several homes were surrounded by water following the break. At least five homes had water reach their crawlspaces or basements, Loughmiller said.
He anticipated the line would be repaired by Thursday night.
Loughmiller said the water company hand-delivered notifications to customers who would need to boil water they intend to use for consumption after service is restored. The boil advisory for those customers was expected to be in place until late Thursday.
The cause of the break was undetermined Thursday afternoon, Loughmiller said.
Spires said the water line runs under Broadway. He said it's beneath the road because water lines there were in place when Broadway was still a two-lane road. It would have been too expensive to relocate the water lines when Broadway was widened, Spires said.
Traffic in a small portion of Broadway was restricted to two lanes Thursday while crews were repairing the line. Part of the road had to be removed for the work.
Spires said Indiana American recently replaced aging water lines that run along Broadway from 93rd Avenue to 78th Avenue in Merrillville. Loughmiller believes the section of line that broke Thursday also is scheduled for replacement.
