The City of Peterborough is advising residents who draw their water from the Otonabee River downstream from Peterborough to boil their water on Monday, January 25th.
The boil water advisory does not affect municipal tap water supplied to residents of the City of Peterborough.
From 9 a.m. to 10 a.m. on Monday, the Peterborough Wastewater Treatment Plant will be discharging partially treated water into the river during planned maintenance on equipment at the facility.
Only one of the six stages in the water treatment process — the ultraviolet disinfection stage — will be bypassed during the maintenance work.
The discharged water will still be treated through all other processes, including screening, grit removal, primary clarification, aeration/biological treatment, and final clarification.
However, residents downstream of Peterborough who draw water from the river are advised to take necessary precautions and boil their water.
