“Life is like a sewer... what you get out of it depends on what you put into it.”
– Tom Lehrer

Many communities with combined sanitary and stormwater sewers are exploring the best ways to reduce the incidence of combined sewer overflows (CSOs).  There has been much made about the battle. . .or more often blending. . . of grey and green infrastructure components to achieve overall CSO reductions.  Green infrastructure approaches show promise in that they can reduce stormwater runoff volumes (and associated pollutant loads) entering the combined system and can have multiple benefits, such as helping to “green” the city.  Many CSO communities are asking the tough questions, such as how much can green infrastructure actually reduce overflows and how do costs compare to the grey alternatives?  How can green infrastructure be incorporated into CSO Long Term Control Plans?  This webcast will explore how various CSO communities are seeking to implement green solutions.
