A strong chemical odour has forced the city to stop sewer repair work in
Ottawa's Hintonburg neighbourhood after homes were evacuated and store owners
complained to the City of Ottawa. On Feb. 2, work began to rehabilitate older
sanitary sewer pipes to seal leaks and cracks, while also extending the lifespan
of the pipes. via
