The City of Omaha will spend about a half-million dollars of sewer bond revenue to study new “green” projects for the city’s ongoing sewer separation project.
City Council members unanimously approved a $498,000 agreement with the Tetra Tech Inc. firm on Tuesday, continuing an effort by public works officials to find environmentally-friendly ways to offset the $2 billion overhaul’s price tag.
One example of how the concept works is seen in the series of concrete walls and ditches that now line the southeastern corner of Elmwood Park.
Stormwater pipe there is designed to send water downhill through a stretch of grasses and plants, then through gaps in the concrete toward a nearby creek, a process that naturally filters and soaks up stormwater runoff instead of sending it to a treatment plant. Officials have said a similar green project at Spring Lake Park in South Omaha could also save millions of dollars.
The city’s agreement with Tetra Tech Inc. says the project is expected “to develop five projects that can proceed into implementation.”
