On either side of Niagara Falls, when it rains, it pours sewage and stormwater
From the Buffalo News:
An estimated 800 million gallons of untreated sewage and stormwater have flowed into the Niagara River from the American and Canadian sides so far this year, eight times more than last year.
It’s enough to pour over the Horseshoe Falls for 20 minutes.
The American side accounts for about three-quarters of the sewage and overflow, according to discharge data The Buffalo News reviewed. But most of the time, neither side’s wastewater system can handle an inch of daily rainfall without overflows into the river.
