Project update

We regret to inform you that the watermain construction work on Diplock Lane has been temporarily delayed.

The Region of Peel was planning to bring the new watermain into service by transferring from the old watermain to the new watermain. Due to supply chain issues, the construction start date has been delayed as work cannot take place until the underground infrastructure is marked on the ground.

Construction timelines

We are working to determine when the proposed works may resume.We will temporarily be reopening Diplock Lane by the end of the day on Friday, October 22, 2022, until we can resume this work.
