PUC Weekly Corporate Activity Notice


PUC wishes to advise the public of the following activities for the week of December 14th, 2015. This notice is organized into four sections; Electrical Line Clearing (Tree Trimming), Water Infrastructure Renewal, Water Operations Activities, and the LED Streetlight Conversion Project.


Each year, PUC Forestry Technicians inspect Sault Ste. Marie’s electrical distribution system. During this process, trees near power lines are trimmed or removed as needed by our line-clearing contractor Wilderness Environmental Services to reduce the risk of contact with high voltage electrical wires. The purpose of this work is to ensure public safety while at the same time improving the reliability of our city’s electrical system by reducing the number of unplanned power interruptions. Completing this inspection and trimming program for the entire city takes approximately three years.

The line-clearing program for 2015 is complete. However, customers are reminded that if they have a dead tree or notice one near overhead electrical lines to please contact PUC Customer Care at 705-759-6522.


The all planned water infrastructure renewal projects for 2015 are now complete.


Operational activities for the week are:

·         Lorna Wells

o   PUC will be test operating the equipment at the Lorna Wells that is presently on standby. These tests are necessary to ensure the equipment functions properly should its use be required in the future. During these tests, the Lorna Well will be isolated from the distribution system, meaning no water from the Well will enter the system. However, during the isolation process, the operation of valves on Queen Street East has the potential to cause flow reversals within the distribution system. This flow reversal has the potential to cause discoloured water in isolated areas.

·         400 block of Trunk Road

o   A developer is installing a commercial water service. During this process, PUC will oversee the testing and commissioning of this new service.

·         Huron Street – Bridge Plaza

o   Construction of the bridge plaza’s new watermain is ongoing.

There is a chance customers in the areas impacted by Infrastructure Renewal, or Operational Activities may experience a change in water quality. This is because anytime there is a significant change in the rate or direction of flow of water in the distribution system, sediment in the watermains can be disturbed and carried along with the water. Customers are asked to contact PUC Customer Care should they experience discoloured water or any unusual change in water quality.


The conversion of Sault Ste. Marie’s 9,050 High-Pressure Sodium (HPS) streetlights to the more efficient Light Emitting Diode (LED) fixtures is underway. Streetlight Conversion began in the east end of the city and is moving west. Customers looking for more information on the project, or for project status updates, are encouraged to visit PUC’s LED project website.

The PUC would like to remind all customers that work scheduled for next week is tentative and subject to change due to weather or resource constraints.
