Black Bldg.: Domestic Water Service Repairs, Aug. 19

August 17, 2021

Domestic water service in the William Black Building will be temporarily unavailable from 4 p.m. to approximately 10 p.m. on Thursday, August 19, due to emergency repairs. 

During this time, hot and cold water will be unavailable, and restrooms in Black Building will also be inoperable. Please use nearby restrooms in the Vagelos College of Physicians and Surgeons Building.

Once work is completed, please allow faucets to run for 3-4 minutes to ensure constant flow and pressure. Water may appear brown at first but will turn clear as it continues to run.

It is suggested that all laboratory work with hazardous materials–including chemicals, biological, and radiological materials—in the Black Building be suspended while water service is unavailable due to the lack of available water for emergency eyewashes, handheld deluge hoses, and overhead emergency showers. Laboratories should perform their routine, weekly performance test on each emergency eyewash and handheld deluge hose once water services resume normal operations to verify proper equipment function.

For questions or concerns, please contact John Kakleas, senior project engineer, at jk3796@cumc.columbia.edu.
