“The city of Portland has decided not to flush millions of gallons of drinking water that might have been tainted by a teenager who urinated at a reservoir. However, the water still won’t be going to customers’ taps. Instead, about 35 million gallons have been diverted from kidney-shaped Reservoir 5 to an empty reservoir to determine how long its quality can last as a public water feature. Officials had planned to drain the water from Reservoir 5 into the sewer system after authorities said Dallas Swonger, 19, was caught on camera two weeks ago appearing to urinate into it. It was the second time in less than three years the city has emptied a Mount Tabor reservoir due to a urination concern.”
