The City of Ottawa has reached an early milestone on its other major underground project — the sewage storage tunnels meant to keep sewage overflows from entering the Ottawa River.
The Combined Sewage Storage Tunnel is a $232.3-million project funded by all three levels of government, but it's been overshadowed by work on the multi-billion-dollar light-rail transit system.
Work began in June 2016 on an access shaft to the site of the future sewage tunnel at the intersection of Kent Street and Chamberlain Avenue.
