On Thursday, the city said investigative work and isolating the leak is more complex than on smaller water mains.
“Once the leak is detected and isolated the repair can occur,” read a statement.
“Primary water mains are large in diameter and carry water from the water treatment plant to the smaller water mains that service surrounding neighbourhoods.”
People in the area south of College Drive and east of the South Saskatchewan River may experience lower water pressure, according to the city.
Homes and businesses in the area are being asked to avoid unnecessary water use, such as watering lawns and washing vehicles, until further notice, according a message on Tuesday from the city’s mass notification system, notifynow.
“Daily activities, such as handwashing, bathing and appliances are allowed. A pressure-drop will be noticeable at your tap,” read the message.
“Water quality will not be affected; water is still safe to drink.”
Motorists are advised the southbound Circle Drive off-ramp to Taylor Street is closed due to emergency repairs.
The following spray pads will remain closed until water pressure is restored:
- Briarwood (Briarwood Park)
- Lakeridge (Crocus Park)
- Holliston (Holliston Park)
- Rosewood (Glenn H. Penner Park)
- Stonebridge (Alexander MacGillivray Young Park )
The city said it anticipates normal water pressure to resume on June 8.
