Eastern Illinois University is doing work this week to install new fire sprinkler systems in its dormitories.

Workers have closed roads to lay a dedicated water line. Work is expected to last at least through the end of the week. The new sprinklers will go into the Ford, McKinney and Weller residence halls. The installations will help the university conform with new student housing fire safety laws.

The university says the three residence halls also will get new fire alarm systems. The total cost is more than $900,000.
