For the first time in nine days, the City of Calgary's water use has dropped below the target level officials say is "sustainable."

According to data on the city's potable water demand dashboard, 481 million litres of water was used on Tuesday, down from 494 million litres on Monday.

The city's target for residential and commercial treated water use is 485 million litres.

For more than a week, city officials pleaded with residents to conserve water and made arrangements with businesses to cut down on usage.

Several of those days saw water usage at "unsustainable" levels, where the system was running so hard that it couldn't be taken off for maintenance and equipment threatened to break down.

In an update on Wednesday afternoon, spokesperson Francois Bouchart said all 12 pipes in Sites 1-4 have been fixed. Paving and backfilling is expected to be completed on Sites 2-3 today, weather permitting.

"The majority of work is progressing ahead of schedule," Bouchart said, adding that paving work is contingent upon the weather and there is rain in the forecast for the next couple of days.

He added that more information on the projected completion dates will be provided at Thursday afternoon's update.
