Crews were working to repair a water main break in Parkville on Monday morning.
The break occurred at just after 8 p.m. on Sunday evening near Wilson Avenue and Parktowne Road.
The Baltimore City Department of Public Works, which handles water issues in Baltimore County, says that about 70 homes are without water in the area.
A nearby Taco Bell and an Auto Zone have also been affected.
There has been no estimate given on time needed for repair.
