Some Lowertown residents are receiving notices that the ground 10 metres underneath their homes is about to be expropriated as the city prepares to dig a large sewage storage tunnel underground to improve storm water management and protect the Ottawa River.

The tunnel is a key component of the Ottawa River action plan, which is aimed at reducing sewage contamination.

It will stretch from LeBreton Flats to New Edinburgh Park. Another tunnel will run north-south along Kent Street. They will cost between $130 million and $150 million, split between the province and city.

During heavy rainfall the tunnels will hold up to 43,000 cubic meters of sewage and water; enough to fill an Olympic pool about 18 times.
