Description
Summary:Lower space requirement, simple operation and economical aspects as well as landscape integration make decentralized natural sanitation systems necessary in eco-city construction. This paper focuses on water management through natural and alternative solutions in urban and peri-urban areas. Results and efficiency of raw wastewater by decentralized natural systems, intelligent storm water management and reuse of treated water in urban irrigation are discussed. Several full scale examples are presented regarding to their removal efficiency and environmental benefits. Their contribution in climate change mitigation is presented as a necessity in today's eco-city conception.
