Blaine officials blame the recent loss of water pressure on an internal power supply failure at the city’s water tower one. They’ve replaced the power supply.

City manager Clark Arneson says this incident and the loss of water pressure on Jan. 8 are not connected, but both deal with the communications system.

“So first time it was software, second time it was mechanical,” Arneson said. “They both feed up to an alert system that did not function as designed.”

Water test results should be in by Monday night.
