Calgary’s outdoor water restrictions will remain in place for now.
The city has been cautiously testing the water system in recent days, and says there were issues at both water treatment plants, including pumps at water intakes.
Mayor Jyoti Gondek says residents can only use their sprinklers for one hour a week and use a hose with a trigger nozzle to water their gardens until further notice.
The outdoor watering restrictions have been in place since a large water main rupture was discovered on June 5.
Calgary and surrounding communities were initially banned from all outdoor water use but those restrictions eased last week.
Voluntary restrictions on indoor water use were lifted three weeks ago.
