Clean Air & Water
Metro21 recognizes air quality and water as serious challenges for cities and its residents. Harmful industrial pollution and automobile emissions degrade air quality and cause severe health risks for exposed residents. Old stormwater and sewage systems, as well as increasingly severe storms due to climate change lead to flooding that threatens neighborhoods and drinking water. Successful solutions marry cutting-edge technology to smart use of green infrastructure and other innovations. Sensors track how well systems are working and guide immediate action and future planning.
