Phase 2 Construction Update: May 29 to June 2
Note: Construction updates are being provided as a courtesy to keep residents appraised of upcoming work. Due to the nature of construction, schedules can quickly change and residents should be prepared for unexpected changes.
The following update is for the week of May 29th:
- Finish replacing water and sanitary service laterals to property.
- Begin process of commissioning new watermain
- Build road structure, including the removal of existing soil, replacement with granular road base material, and installation of sub-drains.
Please note that the commissioning of the new watermain is a rigorous process of testing and certifying that the new watermain is safe to connect to the existing water distribution system. The process includes swabbing, pressure testing, disinfection, chlorine residual and bacteriological sampling tests. The bacteriological sampling requirements are extremely stringent and two consecutive tests taken 24 hours apart must meet bacteriological standards in order to gain approval to connect the new watermain to the existing system. It is not uncommon for tests to fail, however it is rare that the tests fail due to an improperly constructed watermain. There is a joke that a gust of wind can stir up enough dust during sample collection that the sample will fail.
During commissioning the contractor will continue to do as much work as they can concurrently with the testing, but it’s possible they will run out of work that can be performed prior to the watermain being commissioned. At this time it may appear that work on the project has ceased, however that is not the case as sample collection will continue and the project team will be busy trying to determine the cause of sample failures and get the project going again as soon as possible.
Please be advised that CN Rail is continuing construction on the Spurline rail tracks will block roadways in the neighbourhood over the next several weeks. The tentative schedule for this work is:
May 29th to June 2nd – Roger Street
