Smart Water Distribution Network

Brief Description

Smart water distribution network consists of (a) Water Storage points with water level and quality sensors along with water pumps, (b) distribution lines with pressure/flow sensors and electrically actuated valves, (c) Consumer points with flow meters.

The backbone of the smart water network is the water distribution network with electrically actuated valves (butterfly valves) that controls the flow of water to the households, area-wise and street-wise. At the pump side, the system monitors all the electrical parameters of the pump and also controls the pump speed (Variable Frequency Drive) taking the inputs from different control valves at every distribution level. The water level sensors will be designed to monitor the availability of water in the ground level storage points. The system identifies the leaks based on pressure information or with other simpler techniques and informs the authority the position of leak accurately so that the water gets conserved and also helps the authority to send the labour force to the right place of leak in a right time. Water quality parameters like, pH, Turbidity and free residual chlorine are monitored and informed to the authority and also the consumers. Other water quality parameters like, temperature, conductivity, dissolved oxygen would also be considered in the system design. The sensors and actuators data at every place in the water network are wirelessly communicated to the central server for the authority to view and take decisions. Figure below, shows a typical view of any city wide water distribution network.
