The $232-million crosstown sewage interceptor being built under downtown is behind schedule by six months, the city says.

The six-kilometre tunnel network will capture overflows from combined sewers before the diluted sewage enters the Ottawa River. The intercepted wastewater will be sent to the sewage treatment facility.

In a memo sent to council Wednesday, infrastructure director Alain Gonthier says heavy construction was expected to be done in late 2019, but now it looks like it will last about six extra months, extending work into 2020. He attributes the delay to the excavation of the shaft and starter tunnel at Chamberlain Avenue and Kent Street in 2017 and challenges commissioning the tunnel boring machine.
