A water main break near Johns Hopkins Hospital early today sent water cascading into a power plant, briefly threatening to disrupt electrical power to the hospital complex.
Hospital spokeswoman Marion Glick said the water was shut off and patient care areas of the hospital were not affected by the leak, which began at 5:25 a.m.
James L. Kapplin, a city public works spokesman, said the cause of the break in a 6-inch main in the 700 block of N. Durham St. was unknown. The department received a call at 5:40 a.m.
"A person driving a valve truck picked up the call on a police scanner and got there before the job was dispatched," Kapplin said. The main was shut off shortly after 6 a.m. and repairs were begun.
Glick said water from the break entered a power plant in the basement of a hospital office building at 1830 E. Monument St. The plant supplies electrical power to that building, which houses part of the School of Medicine, as well to as patient care facilities south of Monument Street.
"We thought there would be a problem, but there was not," Glick said. "We didn't consider it to be a major flood."
However, water service to the building at 1830 E. Monument St., and to the adjacent Balmer Pharmacy, was cut off. Kapplin was unable to estimate how long repairs would take.
