The city is relying on nature to control storm water.
City Engineer Roger Sparks said the E.P.A. requires that the city use some forms of green infrastructure in their sewer overhaul program.
The city began construction on their first green project near Corby pond last year.
Sparks said the project has several benefits.
"For us what it will provide is also a classroom area for children," he said. "They can walk along it, look at the various plants that will be there...or even plants that grow in shallow water."
Sparks says the green sewer system could also help prevent flooding.
The total cost was about $400,000 and was paid for by the capital improvement tax.
