The sanitary sewer system is made up of more than 258 kilometres of gravity-fed and pressurized main lines. The main lines transport sewage to one of the 6 lift stations. The City of Airdrie pre-treats sewage with nutrients to eliminate sulfides before pumping the sewage back to the City of Calgary treatment plant. Once the sewage is treated by the City of Calgary it is released back into the Bow River.
Residents are responsible to ensure that their wastewater flows freely to the sewer main into the City of Airdrie sanitary system. If you are experiencing a sewer back-up in your residence:
- Call a plumber. The plumber will come to your home and check your sanitary service and clear any blockages. The City of Airdrie cannot recommend specific plumbers. PLEASE NOTE: If the plumber suspects that the backup is due to a structural failure on public property, the City will require a CCTV video to be submitted for review. It is recommended you request a video from the plumber.
- Call Water Services. City Staff will go to your property and check the City sewer main pipes to ensure they are flowing.
