QUINCY (WGEM) — Overnight issues at the Quincy water plant caused a drop in water pressure for roughly 75% of Quincy residents on Friday morning, officials say.
City engineer Jeffrey Conte says everything was back to normal mid-morning.
The issue occurred because of a frozen sensor in one of the tanks at the treatment plant.
Conte said around 12:30 Friday morning the sub-zero temperatures iced out a sensor that monitored tank levels.
"The system thought tanks were full and shut down the pumps and because the line was frozen, even though tank levels were dropping, it didn't restart the pumps.
Conte says frozen sensors happen from time to time and usually get caught pretty quickly by their automated system.
"In this case, we didn't get notified, because it didn't know there was a problem because the line had frozen," Conte said.
Some Quincy residents sat they noticed the difference as soon as they woke up Friday morning.
Celeste Burrell said she woke up around 5:15 Friday morning.
"Well when we went to use the bathroom to get ready for the day, it was very slow."
And she said it didn't stop there.
"In the shower, in the sink. I threw in a load of clothes, it took forever to fill."
Conte said despite the sensor freezing just before 1 a.m. Friday, the city didn't know what was going on until they started getting calls five or six hours later.
Conte said it's a less than ideal start to everyone's Valentine's Day.
"We apologize for the inconvenience this morning, it was a cold morning, but we're sorry you woke up with low pressure," Conte said.
Conte said the sensor should haven been insulated enough to withstand the temperatures.
He said when warmer weather returns, they'll investigate how it froze as well as figure out another method for keeping an eye on the tank level.
