  1. 1. What is Green Infrastructure and HowDoes It Reduce Wet Weather Issues?Making natural systems work for us:using soil and vegetation - rather than concrete and pipe,to manage stormwater volume, rate, and water quality impacts Prepared for: Onondaga County, New York Prepared by: October 2008 1
  2. 2. During dry weather, sanitary flows are collected in combined sewers for treatment at Metro Catch BasinCombined Sewer Sanitary Sewer Dry Weather Flow Creek Interceptor Sewer to Wastewater Treatment Facility 2
  3. 3. During wet weather, inflows exceed the collection system’s capacity and trigger a CSO Roof LeadersStormwater Runoff Catch Basin Combined Combined Sewer Sewer Sanitary Sewer Overflow Creek Interceptor Sewer to Wastewater Treatment Facility 3
  4. 4. Green solutions intercept and reduce stormwater flows to sewers, providing storage, infiltration, and treatment Roof Leader VegetatedStormwater Swale Runoff Porous Roadway Sanitary Combined Sewer Sewer Dry Weather Flow Creek Interceptor Sewer to Wastewater Treatment Facility 4
  5. 5. Green infrastructure reduces…. Flooding Erosion Stormwater runoff volume Stormwater pollutant loadings CSOs Gray infrastructure operation, maintenance, energy and treatment costs 5
  6. 6. Green Infrastructure Technologies and Example Applications Porous pavement  Bioretention/vegetated infiltration  Parking lots  Rain Gardens  Roadways  Vegetated curb extensions  Sidewalks  Tree trenches  Basketball courts  Planter boxes  Cisterns for capture/re-use  Vegetated roofs  Green streets  Combinations of the above 6
