City of Hamilton says 59 million more litres of wastewater flowed into Lake Ontario

The City of Hamilton says roughly 59 million litres of sewage had flowed from 11 homes near Rutherford Avenue and Myrtle Avenue straight into Lake Ontario since 1996. "City staff developed this estimate based on the water meter usage data from the 11 properties connected to the combined sewer pipe," reads a release, which adds this method was identified as the most accurate way to represent the discharge. The city confirmed the sewage leak on Monday during a risk-based proactive inspection program prompted by a separate, 337-million-litre sewage spill discovered in late November.
