Water service was restored to about 1,200 customers Thursday afternoon after a 12-inch water line “blew apart” on the city’s southeast side.

Service was restored to all customers by 1 p.m., said Fernando Molina, a Tucson Water spokesman.

Brian Andrews, vice president of The Ashton Co., said a crew was backfilling a sewer trench “in proximity of the line when it blew apart” near South Harrison and East Escalante roads.

The water line break happened about 6:30 p.m. Wednesday, and Tucson Water provided gallons of water to families during the line repairs, Molina said.

“The (water) line is an old unrestrained pipe system, and it came apart at one of the bends,” Andrews said.

The line was temporarily restored, and temporary road repairs were expected to be completed by late Thursday, Andrews said.

Joggers and bicyclists who use The Loop trail, part of which follows along Harrison Road and the Pantano Wash, can resume using the trail once repairs are completed, officials said.
