Officials are asking residents in and around the city of Edmonton to conserve water following heavy rain and localized flooding on Sunday.

The rain has pushed the region’s stormwater system to capacity, according to an Alberta Emergency Alert issued at 8:55 p.m.

“If the stormwater system continues to operate over-capacity, flooding and sewer backups will continue to increase,” the alert for the City of Edmonton reads.

Similar warnings were issued for nearby cities and towns such as St. Albert, Spruce Grove, Stony Plain, Beaumont and Tofield.

Utilities provider EPCOR says customers should refrain from showering, running washing machines and dishwashers, and should cut back on flushing toilets.

“Every drop matters. Simple steps you take can be the difference in helping neighbours avoid flooding and sewer backups,” EPCOR wrote.

We have crews working across the city managing continued rainfall, and they could use your help. EPCOR is asking customers to immediately take steps to reduce your water use. Until further notice, please defer laundry, your shower or running the dishwasher and reduce the number… pic.twitter.com/HmELt2ubEg
