Listen now (19 min) | In this podcast I interview Angelina Cook, who has been working tirelessly for many years protecting the waters in Mt Shasta and McCloud area, where she is on the Water Council. We have a discussion around grey and green infrastructure of water. Gray infrastructure is human built structures to manage our water system. Green infrastructure, also called nature based solutions, is nature managing our water systems. Gray parts of the infrastructure use dams to store water. Green parts of the infrastructure use wetlands and aquifers to store water. Gray infrastructure uses chemical sewage plants to clean the water, green infrastructure uses wetlands, microbes, fungi, mussels etc to clean the water. Gray infrastructure uses electricity and aqueducts to move water. Green infrastructure uses the sun to evaporate the water and the wind to move it around. Gray infrastructure uses levees, deeper channelized rivers, and dams to do flood control. Green infrastructure uses floodplains, wetlands, rich soil, and vegetation for flood control.
