London 'Micro tunneling' under Wharncliffe Road will open capacity for development A micro tunneling machine will be lowered into this hole as they will drill across Wharncliffe Road in London, Ont. (Brent Lale/CTV News London) Share The City of London has brought in a massive drilling machine to tunnel under Wharncliffe Road. It is part of a $7.
3 million project. “This micro tunneling machine is doing a section of this trunk sewer underneath Wharncliffe Road so that we can get this put in without any disruption to people using Wharncliffe,” explained Ashley Rammeloo, London’s director of water, wastewater and stormwater. She continued, “It's part of an overall project to increase the trunk sewer size that goes between the Downtown and Greenway Wastewater Treatment Plant.
This is important because it accommodates housing, infill and intensification in the downtown, as well as along Wellington Road and the rapid transit corridor. But it also takes more wet weather flow during those big rainstorms.” The machine, belonging to Erritt Construction, has 10 cutting disks and is estimated to weigh more than 80,000 lbs and is worth more than $2 million.
