Two more residential streets will be rebuilt this year as part of Sarnia’s generation-long sewer separation project.
Van Bree Drainage and Bulldozing Limited won two separate contracts to install new sewers under parts of Stuart Street and Queen Street.
Many older parts of the city were built with combined sanitary and storm sewers. During heavy rain or snowmelt the volume in the shared sewers can exceed capacity, forcing the system to overflow. Storm water mixed with untreated human waste, toxic materials and debris can then enter the river and surge up through basement drains.
About 39 kilometres of sewers have been separated since 2004, and about 15 kilometres remain, said city engineer David Jackson.
“In general, it’s going to take us another 20 years to fully separate them all.”
Queen Street south of Devine will be replaced as a cost of just under $2 million.
The winning bid for Stuart Street between Wellington and Talfourd was $935,000.
