Conclusions The WIS has bridged two crucial gaps in the operation of an intermittent water distribution system: For City Residents: • Establishes a two way communication channel between the end-user and the utility
For the Utility: • Extracted additional efficiency from the existing water delivery infrastructure • Reduce operational problems such as unreliability and low water pressure
