Hot and dry weather this summer in Thunder Bay, Ont., meant the Bare Point Water Treatment Plant pumped a bit more of Lake Superior though the city than normal. Based on the past two summers, the plant produced, on average, 42.3 million litres of water per day. The summer of 2021 saw that figure increase by 13 percent, to 47.9 million litres per day, said Erin Marcella-Fui, the plant superintendent. "It's certainly an increase in demand, so our production goes up. We are prepared for that production level, so it didn't impact us that way, she said, noting the plant's maximum production is 113 million litres of water per day.
