Charlotte Amalie High School students were sent home Monday morning due to lack of water at the school. Classes are to resume Tuesday.
Patricia Blake-Simmonds, spokesperson for the Water and Power Authority, said the problem had to do with water pressure.
"The high school has a modified system," Simmonds said. "What that means is the school is on the potable water system, but also has a cistern. When the cistern runs out they use the potable water to fill the cistern. Right now we're having a problem with water pressure."
On Friday WAPA announced that due to two water main leaks, the authority would be switching to a 10-inch standby water line until Saturday morning. The release said the changeover would cause a substantial reduction in water pressure and even the possibility of no water at higher elevations.
Simmonds said she suspected the switchover was part of the problem at CAHS. She said Glenn Rothgeb, assistant executive director for WAPA, had committed to assist the school in any way he could.
The release from Education said arrangements had been made to truck water to the campus from local suppliers.
