The project includes the cathodic protection of approximately 12000m of watermain at various locations including the installation of approximately 1200 anodes and 100 tests stations. The project also includes excavation and installation as well as restoration works. The overall budget is $1.1M including design and construction.
This program is intended to apply cathodic protection to all ductile iron mains that are not otherwise proposed for replacement in other capital projects, and that fall within the recommended age (40 years or younger) to maximize the benefit of cathodic protection. Installation of cathodic protection is expected to increase the life of ductile iron watermains by up to 15 years.
The City of Barrie has approximately 177,700m of ductile iron watermain, (nearly 30% of the city's water distribution network). Watermains made of this type of material are prone to corrosion-related physical failure. Ductile iron watermains are more prone to corrosion than non-iron pipes. This results in damage to the pipe surface, including pitting, scaling, and other depressions, which eventually leads to cracks, holes, physical failures, and watermain breaks. This type of damage substantially reduces the maximum potential life of these watermains, resulting in increased operational and emergency repair costs and service disruptions.
Cathodic protection involves the installation of sacrificial anodes connected to ductile iron watermains. The attached anodes will corrode (rather than the watermain to which they are attached) thereby extending the life of the watermain.
Locations for 2018 cathodic protection include:
• Leacock Dr
• Longman Dr
• McVeigh Dr
• Mowatt Cr
• Scott Cr
• Shelly Lane

August 3, 2018
Construction is completed.
July 3, 2018
All streets will be completed by July 6, 2018.
June 8, 2018
The Contractor will begin work June 11, 2018. Work on each street shall be completed within one (1) to three (3) days depending on the length of the street. Single lane closures during the duration of the construction is expected.
Water, sanitary sewer, Hydro, telephone, Cable TV, and gas services should not be affected by the construction, barring any unforeseen circumstances.
All reasonable efforts will be made to maintain vehicle access to driveways. However, there may be some temporary interruptions to access during construction. Access will be restored as quickly as possible. The Contractor will provide prior notice of any imminent access restrictions to the businesses and residents. Pedestrian access to all homes and businesses will be maintained during construction.
The contractor is required to conduct his work in a safe manner, including fencing of deep excavations, etc. We ask that you take extra caution during the construction period to ensure everyone’s safety
All roads will remain open to through traffic during construction, although lane closures and restrictions can be expected in order to accommodate construction activities. We ask for your patience in such instances.
