Roof-top Runoff Jinya Yamakawa
background Nyc sewer system is 6600 miles First modern sewage treatment plant in the us : late 19th century each year snow and rain end up as billions of gallons
structure
What’s the issue? Health issues Beach closings Swimming/fishing advisories Habitat degradation
What’s the cause? The High volume amount of water that is released into our water system too quickly with each rainfall Impervious surfaces such as concrete or asphalt prevent water from naturally The water picks up polluted materials from the surface
Green roofs A rooftop filled with vegetation and a growing medium. Provides insulation, a wildlife habitat and absorbs water.
Water barrels Stores rain water Provides water storage, recycling water, prevents sewage contamination.
other solutions Revise state/local regulations to encourage green roof infrastructures. Re-construct all piping's under the asphalt/concrete/buildings. Develop infrastructures with green roofs pre-installed.
