Our Standard Excavation Process
There are several steps we undertake to rehabilitate our water distribution and wastewater collection systems.
Our starting point is to call Utility Safety Partners (USP) with the area we plan to perform ground disturbance activities at. During this process you will see Facility Locate Technicians from Atco, Telus, Shaw, EL&P (and other shallow utility representatives) in and around your property. They will be leaving paint marks and flags to mark the locations of the underground utilities in the area. See our utility locations page for further information.
Once the utility locates have been completed, the site is scheduled for excavation. The work should be completed within 30 days of the original facility locates. If the work was unable to be completed in the initial allocated timeframe (possibly due to many factors such as pop-up emergency work, inclement weather, current progress on previously scheduled work, and other factors), we will need to re-locate the area and re-schedule the work for a later time.
Using heavy equipment and City staff, we will complete the repair or replacement on the deep utility, (i.e. water / sanitary / storm sewer). The excavations can vary in size depending on the depth and the scope required to complete the rehabilitation. Please note that during the excavation process, we use heavy compaction vibratory equipment to compact the ground as best we can to help lessen settlements and deterioration of our trench. Please secure any valuables from being damaged during this process.
During the completion of the work, short interruptions to the supply of water may occur. During any periods that the water is shut off, water cooled or dependent equipment should be checked and/or shut down, and checks should be made to ensure all faucets are closed. Once the water is turned back on, the water should run for a few minutes, or until the line is clear of air.
After the work is complete, the crew will do their best to leave the job site clean and organized. Our goal is to leave the property functional and clean up any debris that was made during the excavation process.
Our current standard is to repair private property that we have disturbed during excavations. The first step of our reinstate process is to have Parks and Public Works Department (PPW) complete all concrete and asphalt repairs.
Once concrete and asphalt have been installed, we will complete our landscaping and fence repairs. All private property landscaping repairs are contracted out. For further information regarding our landscaping reinstatement process please call 403-342-8750.
If our excavation was completed late fall or winter, concrete and asphalt repairs will commence in the spring or early summer. For further information regarding asphalt and concrete reinstatement, please call 403-342-8238.
