In order to construct a sustainable residential community a number of components need to build up and function well such as good quality housing apartments, efficient transport, children parks, green area, security, community center and a decentralized waste management facility. Water used in a community includes drinking water, rain water, ground water and wastewater. Wastewater coming from the housing complex are referred to as grey water that includes wastewater from washroom, kitchen, hand basins and black water that includes wastewater from toilets.
Wastewater from residential complex requires proper treatment and treated water can be used for saving freshwater sources and can be used in recreational activities. In this context, CWs technology can be used for treating Grey and Black water from residential complex due to low energy requirement, cost effective system with no odor and harmful gas emissions.
