At 10:45 this morning, Clemson University closed offices and canceled classes because of low or no water pressure in many campus buildings. A break occurred this morning in the line from Anderson to campus. Residence and dining halls remain open for students, but conservation is ordered, with limited use of toilets and no showers or other non-essential water use. A boil water advisory is in effect. Water should be boiled at least five minutes during the next 48 hours.
