Designed to be a response to the environmental crisis, the Tongzhou Project is largely self sufficient in terms of Energy and Water uses. The Tongzhou Ecocity is considering water as a primary vector for urban infrastructure. All waste water is recycled on site, part of the land is dedicated to production of renewable energy with a windmill farm and extensive implementation of hot water solar panels. Rainwater and grey water are treated within the boundaries of the project through a network of constructed wetlands and greenhouses serving the dual purpose of enhancing the aesthetic value of each neighbourhood and creating green waste and then irrigates parks and gardens. The overall master plan encourages walking, cycling and use of public transport.
