Calgary’s water demand stayed below the city’s conservation target Thursday, marking the fourth straight day the system has remained in the “green zone” since Stage 4 water restrictions took effect Monday.
Data from the City of Calgary’s Water Demand Dashboard, updated early Friday, shows water use reached about 482 million litres Thursday, staying below the 500-million-litre daily demand threshold officials set while the Bearspaw South Feeder Main is shut down for reinforcement work.
The City said in a Thursday update that Wednesday’s water demand was 489 million litres, also within the target range.
“Since restrictions came into effect on Monday, water use has stayed in the green zone every day,” the City said.
The target is intended to reduce strain on the water system while the feeder main remains temporarily out of service.
The feeder main — a major pipeline carrying treated water from Calgary’s Bearspaw Water Treatment Plant — was shut down earlier this week so crews can reinforce nine pipe segments.
According to the City, six segments are located along 16 Avenue N.W. near Sarcee Trail, while three are at Point McKay Park.
Additional work is also underway along 33 Avenue N.W., where crews are repairing valves and preparing for the future connection of a new steel feeder main. Valve repairs are expected to take about 10 days.
City officials say the feeder main will remain out of service for about three and a half more weeks while the reinforcement work continues.
The restrictions apply across Calgary’s drinking-water system, which supplies several surrounding municipalities including Airdrie, Chestermere, Strathmore and Tsuut’ina Nation.
In Airdrie, Level 4 water restrictions also took effect March 9, including a complete ban on outdoor water use for residents and businesses.
