OAKLAND -- A plumbing issue at Alta Bates Summit Medical Center forced staff to shut off all water to the facility for hours, resulting in canceled surgeries and water use restricted to urgent care cases.

Around 1 p.m. Tuesday, a plumbing failure resulted in a major disruption in the medical center's water supply and a "Code Dry" was called at the hospital's Merritt Pavilion in Oakland, according to medical center spokesperson Carolyn Kemp.

Code Dry means no use of water except for urgent patient care issues.

Back-up procedures were put in place and all essential food, water and supply needs were met with minimal service disruptions, Kemp said.

As of 5:15 p.m., the Code Dry was canceled and water service restored and at normal capacity.

Water quality coming into the medical center was never affected, Kemp said.

As a precaution, the medical center took a "conservative approach," according to Kemp, and all elective surgeries have been postponed for at least 24 hours as the center works to fully restore operations.
