PUC wishes to advise the public of the following activities for the week of July 17th, 2017. This notice is organised into four sections; Electrical Line Clearing (Tree Trimming), Water Infrastructure Renewal, Water Operations Activities, and Unidirectional Flushing Program (UDF).

Electrical line clearing program (Tree trimming)

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 Asplundh Canada 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 four years.

For the week of July 17 – 21 street tree trimming will continue in the area of, Third Line West and Carpin Beach Road. 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.

Water infrastructure renewal

This year’s Water Infrastructure Renewal Projects (Street Reconstruction)are underway. The PUC will be working with city staff to keep affected customers informed on the following renewal projects:

  • Franklin Street
  • Grace Street
  • John Street (City Aqueduct Project)

Water operations activities 

Operational activities for the week are: 

Annual Hydrant Testing

  • The testing of the city’s 2,500 fire hydrants is currently underway. This work is necessary to ensure all hydrants are functioning properly. Testing will occur across the city throughout the summer. There will be no hydrant testing on weekends and holidays.

Bridge Plaza - New Water Service

  • A developer is installing new commercial water service at the Bridge Plaza (at Queen Street West and Hudson Street). During this process, PUC will oversee the testing and commissioning of this new service.

John Street

  • Commissioning of the new watermain is underway.  

There is a chance customers in the area impacted by operational activities may experience a change in water quality. This is because anytime there is a significant shift 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.  

Unidirectional flushing program

PUC water customers are advised that the Unidirectional Flushing (UDF) Program for 2017 is underway in the east end of the city. Customers are encouraged to visit the PUC website at for regular updates and to see a map(s) of the flushing area. The UDF Program is performed to remove sediment from within the city’s watermains and is a recognised industry best practice for improving water quality.

  • UDF flushing for the week of July 17th – July 20th will occur in the area generally bounded by Shannon Road to Sutton Park, and Trunk Road to Greenview Lane (map).

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.
