Residents of Onoway, Alberta woke up Tuesday morning to find bright pink water pouring out of their taps.
The residents of Onoway, Alberta, complained to their town office on Monday.
The pink water was a side-effect of potassium permanganate, a common water-treatment chemical, the mayor said.
The town office said the chemical got into the reservoir when a valve malfunctioned during “normal line flushing and filter backwashing”.
The mayor said there was no public health risk to residents.
Mayor Dale Krasnow apologised saying the town “could have done a better job communicating what was going on”.
Resident Trevor Winfield wrote on Facebook his “water was broken” when posting a video of the pink water.
The town office said in a statement: “The reservoir was drained, however some of the chemical still made it into the distribution system.
“While it is alarming to see pink water coming from your taps, potassium permanganate is used in normal treatment processes to help remove iron and manganese and residents were never at risk.”
