Cold shuts down some Tucson Water pumps
Freezing temperatures shut down some Tucson Water pumps overnight, leaving over 1,000 homes and business without water service, a spokesman said.
"The extreme cold has caused electronic control instrumentation at various reservoir and booster sites to malfunction, automatically shutting down pumps," said Tucson Water spokesman Fernando Molina
Temperatures dropped to a record low of 18 degrees, the National Weather Service said.
Work crews are being sent to reset the systems Thursday morning, Molina said.
The affected areas included Corona de Tucson and Diamond Bell Ranch in the pre-dawn hours, he said.
"The outages have kept crews busy all night, but so far none of the incidents have been the result of frozen water pipes," he said in a news release.
"It is possible that home plumbing may be affected by frozen or burst water lines," Molina said.
Customers can call 791-4133 to report water outages.
Hard freeze warnings are effective until 11 a.m. Thursday, and overnight from 9 p.m. until 10 a.m. Friday.
