Work being completed on two major sanitary sewer projects will impact traffic in busy areas of Mississauga in the coming weeks and months.
Peel Region officials said this week that work to rehabilitate the sanitary sewer at Dundas Street West and Old Carriage Road, just west of Erindale Station Road by Westdale Mall, will affect road traffic for at least the next six weeks.
“The contractor will be required to perform work within the left-turn lane on Old Carriage Road. During this work, left turns from Old Carriage Road onto Dundas Street West will not be permitted,” Peel officials said in an Oct. 12 project update.
The left-turn restriction will be in place “intermittently” until Nov. 30, the region added.
Project leaders said work crews will clean the sewer pipe and place a new resin (plastic) lining inside to extend its life. They added the work will be completed underground and will not require digging trenches in the neighbourhood.
Region officials said sanitary sewers “are underground pipes that carry wastewater from your home to a water resource recovery facility. Wastewater is created when water goes down a drain or toilet.”
Weather and other factors could cause delays and extend the timeline of the project beyond Nov. 30, project officials noted.
The work is being completed by Capital Sewer Services Inc. under contract to Peel Region. Working hours are from 7 a.m. to 7 p.m., Monday to Friday.
Officials said area residents and businesses will be notified at least 24 hours in advance of any temporary wastewater service interruptions.

Will Mississauga ever get a subway?
During those periods, people “may smell odours, which will go away within a few hours,” project leaders said.

Meanwhile, in southwest Mississauga, work crews are installing new sanitary sewers that will result in some closures in the coming weeks and months.
Starting Oct. 13, Avonhead Road will be closed to all through traffic at Royal Windsor Drive until Oct. 30, the region said.
Traffic on nearby Southdown Road and Royal Windsor Drive has also been impacted as the work has progressed.
“Peel Region has been installing new sanitary sewers along Southdown Road and Royal Windsor Drive. Local impacts along Avonhead Road are also planned to facilitate abandonment of existing sewers,” regional officials said in an earlier project update. “This work is required to keep providing (the area) with high-quality wastewater services.”
Construction in the area is expexted to finish by the end of the year.
“We understand construction can be disruptive, and we appreciate your patience as we work to improve our community’s infrastructure,” project leaders said in their earlier update to residents, motorists and businesses. “This work both maintains and improves Peel’s world-class water systems, allowing us to provide reliable wastewater services to support a thriving community for life.”
