A large water main break has cut flow to most of the city’s South Side on Monday evening.

The break was first reported around 5:43 p.m. near the intersection of East Third and Hayes streets, according to Northampton County 911 dispatch.

According to the city’s Emergency Service Center hotline, the break was affecting a 15-inch water main, with almost all of the South Side experiencing either no water or very low water pressure.

The Bethlehem Water Authority is working to repair the break, but there was no ETA for repairing the line as of about 7:30 p.m.

Bethlehem police are also on scene to direct traffic at the busy intersection, located near Artsquest’s SteelStacks campus and the Wind Creek Bethlehem casino.

Lehigh University issued a safety alert to its campus community reporting that the campus was impacted by the break.

The safety alert urged the campus community to use as little water as possible, and turn off any laboratory equipment that requires continuous water pressure, until the break is fixed.

By 9 p.m., some customers on social media who had lost water service reported getting it back, though others were still experiencing low pressure.
