Cincinnati’s green approach to sewer discharge expected to save $100 million
By Peter Fabris, Contributing Editor
Under orders from the U.S. Environmental Protection Agency to largely eliminate the flow of sewage into rivers and streams, Cincinnati is moving forward with a plan using green solutions.
The city’s approach to controlling storm runoff will include a one-mile-long restored stream, water features, rain gardens, a recreation area, and a trail. Officials believe that results of the green approach will include revitalization of blighted areas, cleaner air, cooler temperatures, and less flooding.
The green alternative to a concrete tunnel to hold overflow for later treatment is projected to cost $100 million less to construct. Green solutions can help many communities reduce stormwater runoff, but cannot by themselves be the answer everywhere.
Pittsburgh, for example, with its numerous hills, has a much different topography than Cincinnati. Pittsburgh officials favor a combination of green and gray approaches to meet the requirements for reducing the outflow of sewage into the Ohio River.
