The ongoing rainfall and snowmelt is causing a significantly increased volume of water entering the Wastewater Treatment Plant, according to a City of Peterborough media release.
As a result of the current conditions, the Wastewater Treatment Plant is now in secondary by-pass mode. This means that while all of the sewage will be screened and will receive primary treatment and UV disinfection, it will not receive the secondary polishing treatment. Residents downstream of Peterborough who draw water from the river are advised to take necessary precautions and boil water.
