HAMILTON - The City of Hamilton is estimating that approximately 59 million litres of waste has been dumped into Lake Ontario over more than two decades as the result of a sewage leak discovered this week.

The city says it developed the estimate based on water meter usage data from the 11 residential properties connected to the combined sewer pipe in the 27 years it went undetected.
