Imagine one of the Great Lakes on a sunny day – the water is clear and kids are playing in it. But the day after a big storm, that same lake can reek of raw sewage.
It’s caused by a combined sewer overflow – a common problem in over 700 cities and towns nationwide. Some cities are finding a solution underground.
By 2035, Cleveland will be home to seven enormous tunnels sunk more than 200 feet below ground. The Northeast Ohio Regional Sewer District is constructing tunnel number two on the city’s east side, just a couple of miles from Lake Erie.
