Sixty-six million litres of combined sewage overflow sloshed into the Ottawa River during Sunday's record rain fall. That's the highest amount of mixed storm water and sewage water to overflow into the Ottawa River in the past 12 months.

On Sunday, 36.4 mm of rain fell, smashing the old record for June 5th of 15 mm set in 1975. There are currently 18 locations in Ottawa where sewer overflows may enter the Ottawa River.
