Temporary cutbacks aim to protect regional supply during feeder-main connection
The City of Airdrie will implement Level 4 water restrictions beginning Nov. 4, prohibiting all outdoor water use and asking residents to adopt indoor conservation measures for approximately four weeks while crews complete a critical connection to Calgary’s new Bearspaw South Feeder Main.
The connection requires the existing feeder main to be temporarily shut down, reducing the system’s distribution capacity to about 500 million litres per day. Municipal officials say the restrictions are intended to maintain adequate supply for essential services during the tie-in and commissioning work.
“Conserving water during the connection work is important to ensure enough supply remains available for essential services, including firefighting and emergency response.”
What residents are being asked to do
City guidance lays out specific indoor conservation steps to limit demand while the feeder main is offline. Key recommendations include:
- Limit showers to three minutes or less
- Flush toilets only when necessary
- Run only full loads of laundry and dishes
- Repair leaks and dripping taps promptly
Officials also warn that some routine activities and businesses may be affected. Pools and arenas are expected to remain open, but outdoor community ice-making could be disrupted depending on weather. Businesses with high water demands may require additional guidance, and certain construction and development activities that rely on outdoor water for grading, compaction or dust control could face limits.
Project timeline and regional impact
The Bearspaw South Feeder Main connection is one of the final steps in bringing the new line online. The new feeder main is expected to be fully operational by the end of 2026. After the physical connection is made, crews will carry out commissioning work that includes disinfecting the line, filling it with water and completing required water-quality testing, a process expected to take two to three weeks.
The temporary restrictions will not be limited to Airdrie. Calgary, Chestermere, Strathmore and the Tsuut’ina Nation will follow the same measures during the connection period.
| Item | Detail |
|---|---|
| Start date | Nov. 4 |
| Duration | Approximately four weeks (connection and initial commissioning) |
| Reduced daily distribution | 500 million litres per day |
| Final commissioning | 2–3 weeks after connection |
The restrictions are framed as a short-term inconvenience to secure long-term improvements in regional water infrastructure. Once the new feeder main is commissioned and water-quality testing is complete, supply capacity will be restored and the temporary measures lifted. Municipal staff have indicated that the new main is a necessary step toward enhancing resilience across the Calgary region’s distribution network.
For residents and businesses, the immediate consequences are practical: reduce non-essential indoor water use, postpone outdoor washing and landscaping, and prepare to adjust operations where water is a major input. City and partner utilities will likely issue further operational guidance to industries and construction projects with higher water requirements in the coming days.
