No 'feasible' solution to sewage overflow from Ottawa storms

No 'feasible' solution to sewage overflow from Ottawa storms

When Ottawa was hit by more than 75 millimetres of rain last week it filled a $232 million sewage tunnel, sending nearly 316 million litres of raw sewage into the Ottawa River. Unfortunately, it's not unexpected or unusual. "It was always known that if there were very large storms the city would be faced with a choice of either flooding sewage into people's basements or into the river," explained Dianne Saxe, a former environmental commissioner and the last person to hold that provincial post.
