The plumbing issues in Madison Hall that shut off water to the residence hall’s occupants Friday evening were caused by a blockage in D.C’s sewer lines, a University official said Sunday evening.

John Ralls, senior adviser for communications and outreach in the Office of the Executive Vice President and Treasurer, said in an e-mail that the problems were first reported at around 8 p.m. on Friday and the building’s water was turned off to prevent further backup.

“Water was turned off to prevent  further backup and GW staff snaked building lines to clear blockage with water service resuming around midnight,” Ralls said in an e-mail.

Ralls said facilities resumed the water services to the building later Friday evening, only to turn the services off again when additional blockage occured. Water was turned on permentalty at around 2 a.m. Saturday morning.

The boiler room in the basement of Madison Hall accumulated six inches of water Friday but all repairs are expected to be completed Monday, Ralls said.

A plumbing issue in Madison Hall shut off water to the building’s residents Friday evening, according to an e-mail sent to students by a University official.

Mohamed Kamara, an assistant property manager with Residential Property Management, said in the e-mail that RPM was “hard at work” repairing the issues but was unable to give an estimate of when the water would be turned back on.

“Even though we are currently hard at work with the repairs, I cannot at present inform you on the duration of the water outage,” Kamara said “However, we will be updating you every hour on the status of the ongoing repairs.”

University spokeswoman Michelle Sherrard and Senior Adviser for Communications and Outreach in the Office of the Executive Vice President and Treasurer John Ralls did not return a request for comment late Friday evening.

Some students living in Madison said they were concerned that if the water outages continued, they would have no place to shower or use the restroom.

“It’s really inconvenient. Where are we supposed to go to the bathroom, Gelman?,” freshman Margot Silverstein said.

According to the GW Housing Programs Web site, Madison Hall can house up to 222 residents.
