Butler residents saw water cascade down Elm Street between East Brady and East Walnut streets Thursday afternoon.

Bruce Bryner Jr. of Butler said he was traveling east on Brady Street when he came upon the scene. He said at around 3:30 p.m. Thursday the street's surface swelled and broke apart, giving way to the water.

Pennsylvania American Water responded to the scene, where they found that a 10-inch cast iron water main had burst, according to Gary Lobaugh, external affairs manager.He said the pipe was more than 70 years old.

Lobaugh said 50 customers will be without service for the day, but they should have service restored by midnight. He said water will be available at the construction site for customers.
