Alta Vista Services Upgrade


The water and sewer pipes in Alta Vista are some of the oldest utility pipes in Whistler. The work is necessary to minimize the risk of failure of aging pipes, reduce water loss from leakage, minimize ongoing odor issues and reduce maintenance costs.

The Hillcrest Culvert replacement that is scheduled for 2023 is a full inline replacement of the existing infrastructure. The existing corrugated steel culvert will be replaced with a larger diameter concrete culvert. The project team explored a trenchless repair method for the aging infrastructure, and unfortunately it was not feasible due the existing condition of the culvert. The work zone will be remediated upon completion of the culvert installation. The works are scheduled to take place from July to October 2023.


Coastal Mountain Excavations Ltd. will remain the contractor for the completion of work scheduled for 2023. Please see the list below of work to be completed in 2023.
