Sewer Backup / Blockage RemovalManhole Cover

If your sanitary sewer service line from the house to the sanitary sewer main in the street is plugged or showing signs of backup, you have the option to contact a local plumber / drain cleaning service or Environmental Utilities.

Effective April 1, 2020, Environmental Utilities will charge a fee to clear sewer blockages on private property. City field operators will clear the blockage during business hours Monday to Sunday between 8 a.m. and 4 p.m. For fee information, contact Environmental Utilities at 403.529.8176 during business hours.

If the problem is in the evening / over night (from 4 p.m. to 8 a.m.), you may choose to call a local plumber / drain cleaning service, or wait until business hours for Environmental Utilities field operators to attend. Note that fees may apply for City field operators to attend.

The service performed by Environmental Utilities is contingent on there being proper access to the sewer cleanout and plumbing installed in your home. If the field operators are unable to access the internal sewer cleanout, it will be recommended that you contact a local plumber / drain cleaner. If an external sewer cleanout is located at the property line, field operators will clean the City owned portion of the sewer service at no cost to the homeowner.

Routine Maintenance

Effective April 1, 2020, a routine sewer maintenance is a service that will no longer be provided by Environmental Utilities. It is recommended that you contact a local plumber / drain cleaner or rent a machine yourself to complete a maintenance on your sewer service line.

Sanitary Sewer Main Flushing

The sanitary sewer collection system will be flushed in the event of a sewer main blockage or overflow. The City has a routine sewer main flushing program that is carried out year-round to minimize the chances of backup in the mains or overflow from a sanitary manhole. Refer to the Sanitary Sewer Maintenance Programs page for more information.

CCTV Inspection

CCTV (closed circuit television) Inspections are completed on sanitary sewer services and mains to assess the condition of the sanitary sewers. The CCTV inspections help determine whether repairs are required or if there is a problem within a sewer line that requires attention. Should you be experiencing frequent sewer backups and are unable to determine the cause, it may be recommended that you have a camera of your sewer service line completed. Results will be provided to the homeowner and follow-up by Environmental Utilities supervisory staff completed as necessary. Please note that, effective April 1, 2020, fees for a CCTV Inspection may apply.

Sewer Line LocatesLocates 2

If you are planning to dig or excavate the ground in any way, it is your responsibility to submit a locate request through Before You Dig Partners - AB One Call. If you are digging in proximity to City owned sanitary or storm sewer lines, your locate request will be forwarded to Environmental Utilities (MHENVU) to review and attend as required. Contact Alberta One Call by calling 1.800.242.3447 or online at before you begin to dig. Ensure you allow at minimum, 2 business days for the locate to be completed.

For Commercial or Construction related locates, Environmental Utilities locators will meet at the same time as scheduled by the Gas and Electric utilities.

For residential locates, the field operator will locate the curb stop (water service valve) which is generally found at property line; the sewer service (in most cases) runs parallel to the water service line. If the work you are performing will not go near the water or sewer services, Environmental Utilities admin staff may provide a clearance ticket number for your reference.

Should you require a more detailed locate of the sanitary sewer service for demolition or repair purposes, please indicate this on your locate ticket submission.

For additional information, contact Environmental Utilities at 403.529.8176.
