Oakland University officials said Tuesday that a third leak was found in its high-temperature hot water system.

The news comes about three weeks after they first reported the first leak in the system was found during the Thanksgiving holiday break.

“Following pressurization of the university’s high-temperature hot water (HTHW) system on Tuesday, a third leak emerged due to temperature and pressure fluctuations,” school officials said in a letter sent to students and faculty. “Many buildings on campus continue to have only partial heat, and modified university operations will remain necessary until further notice.”

The officials also said supervisors in buildings with low heat will continue using limited on-campus staff to manage operations, and remote work is encouraged wherever possible.

Furthermore, the university’s Kresge Library building will remain closed for the remainder of the year, officials said. The library is scheduled to reopen at 10 a.m. on Jan. 4.

In addition, the school said commencement exercises will proceed as planned.

“The community is also advised that the university is executing plans to ensure that the campus is fully open and operational for the Winter 2026 semester,” the letter said. “The university appreciates the patience and understanding of campus community members while efforts are made to maintain campus infrastructure.”
