Water and heating issues have been reported at the Northwest Expressway and Portland Avenue campuses of the Integris' Baptist Medical Center.
A spokeswoman told News 9 the water issues began about 7 p.m. Tuesday and have been ongoing.
City officials told the hospital system they have identified the issue and hope to have water restored as soon as possible.
The Portland Avenue campus has also had problems with its boilers. This has caused issues with consistently heating the building, but hospital staff have a temporary solution in place.
The main operating rooms at the Northwest Expressway campus are still operational. The ancillary departments located in the main building are also operational.
Surgeries from the Portland campus have been moved to Northwest Expressway.
