Imagine you are a municipal sewer system operator in an urban area. You probably would be well aware of the millions of gallons of untreated water that enter your combined sewer systems creating a big old mess in your local water bodies. But what if there was a cost effective solution available? And even better than low-cost, what if the solution made your community pretty and created a great community for people to live, work and play? You would jump on it, right?

Well, many communities with combined sewer overflows have been using green infrastructure – rain barrels, rain gardens, greenways, green roofs etc. – as an attractive way to reduce the stormwater runoff that goes into a sewer system. (We have blogged about it many times before.)  Green infrastructure helps reduce capital costs – traditional grey infrastructure made of pipes and other systems is often cost prohibitive – and has been shown to also reduce operational costs at publicly owned treatment works.

EPA scientists helped develop a resource guide to help more communities manage stormwater and wastewater with green infrastructure. The resource, released Greening CSO Plans: Planning and Modeling Green Infrastructure for Combined Sewer Overflow (CSO) Control (pdf),” will help communities make cost-effective decisions to maximize water quality benefits. The resource explains how to use modeling tools such as EPA’s Stormwater Management Model to optimize different combinations of green and grey infrastructure to reduce both sewer overflow volume and total number of overflow events.  The guide also has relevant case studies to showcase how different communities are using green infrastructure.

Hopefully using this resource can help you plan green infrastructure solutions and provide a variety of tools that can help you measure and reduce stormwater runoff.

    Future Developments : Green Desert For Global Community.-

    Concrete, illegal logging and urban cities cut down the water reservoir so the Global Community should look for replacement area, one of its is desert. Could we change it and then, probably, Mars, and other…?
