Toronto faces multi-million-dollar fines for sewage overflows
September 21, 2009

Canada's largest city could face multi-million-dollar fines for allowing untreated wastewater to spill into Lake Ontario back in 2006. As with most overflow events, the 2006 incident was the result of heavy rainfall that overwhelmed the capacity of the municipal wastewater-treatment plant, but it was made worse when plant staff apparently forgot to reinstate normal controls to keep the sewage from bypassing the plant once conditions returned to normal. In most overflow situations, the inflow of rainwater is sufficient to dilute the sewage down to contamination levels that are more or less safe for the environment -- but they are still carefully regulated and monitored.

We offer several methods of wastewater disinfection that can be used to scale up treatment capacity in case of emergencies, including ultraviolet disinfection and tablet-style chlorination. Please feel free to contact us with your questions.
