ALEXANDRIA, July 12, 2019 – On Monday, July 15, the North Glengarry Water Works Department will break ground on a project that aims to improve the water distribution network in downtown Alexandria, by replacing a number of watermains.

The impacted areas have been broken into phases. 

  • Phase 1- Mill Square from Main Street South, to Ottawa Street and Ottawa Street from Kenyon Street West to Mill Square.
  • Phase 2- Catherine Frasier Street, from Harrison Street to Ottawa Street.
  • Kenyon Street West (1 day) for water main tie in.

During this process, affected residents will be placed on a temporary overland service.  During the installation of this piping, residents can expect short service interruptions.  Staff may have to enter the residences to ensure service connections.  Once on the temporary service, residents will be placed on a mandatory boil water advisory.

The Water Works Department is focused on improving the distribution system to ensure better water quality and to remove system risk when possible.  The existing iron pipes that were historically used throughout the municipality are still operational, and maintain structural integrity, but they are more susceptible to degradation and breakage due to soil conditions and lack of flexibility.  They also have shown increased tuberculation (build up of corrosion inside iron pipes) in lower flow areas, reducing available flows to residents and increasing the likelihood of water colour issues.  Current practices now prefer PVC mains, which have the structural integrity, but are more flexible and do not interact with soils and distribution water, as iron-based materials do.    

The watermain running from Ottawa Street to Mill Square is a 100 mm (4”) ductile iron pipe that dead ends just prior to Main Street South. During the extended cold snap in 2015 the watermain froze, due to low flows.  This watermain is being replaced with a 150 mm (6”) PVC pipe that will be connected to Main Street, ensuring increased water quantity and improved quality.  It is unclear the age of this pipe, but it is estimated to be more than 50 years old.      

The watermain on Catherine Frasier Street is a 19 mm (3/4”) copper pipe that dead ends just prior to Ottawa Street. This watermain is being replaced with a 150 mm (6”) PVC pipe that will be connected to Ottawa Street, ensuring increased water quantity and improved quality.    It is unclear the age of this pipe, but it is also estimated to more than 50 years old.

During this project new fire hydrants will also be installed. This will allow for greater access and safety for our residents. New hydrants will be placed in Mill Square and on the corner of Kenyon Street West and Ottawa Street.

Throughout this process, there will be moving road closures. In some areas, traffic will be restricted to local traffic only. We apologize for any convenience this may cause and we will do our best to reduce disruption where possible.

How Will I be affected by this project?

  • Affected residents will be asked to boil their potable water before consuming it or using it to prepare food.
  • Some roads will be closed to enable crews to work.
  • Some roads will only be open to local traffic.
  • Trucks and heavy equipment will be operating and motorists will be asked to reduce their speed and obey the direction of our flaggers and construction staff.
