Students at eight Arbutus and Lansdowne schools received an extra day of winter vacation Tuesday morning after a water main break near the 2300 block of Research Avenue forced the schools to close.
Baltimore County Public Schools closed Arbutus, Halethorpe, Lansdowne, Relay and Riverview elementary schools, Arbutus and Lansdowne middle schools and Lansdowne High School.
Baltimore City Department of Public Works spokeswoman Celeste Amato said at 4:15 p.m. on Tuesday that crews were investigating the cause of the break.
Amato noted that about an 18-inch chunk came out of the transmission main that serves Anne Arundel County and also connects to the pipes that serve the southwestern portion of Baltimore County..
The main, made of concrete, was installed in the 1970s and was near its "useful life expectancy," Amato said.
Herndon said the schools, like many other residences and businesses in the community, had little to no water pressure.
"We have to, obviously, have good running water when schools operate," Herndon said. "We decided to close today, since there seems to be a pretty big break down there."
Amato said that St. Agnes Hospital had "water pressure issues" early in the morning, but they were quickly resolved.
"People have really had water all day," Amato said. "We've been able to work around the break."
Herndon said he anticipates that the schools will reopen tomorrow.
