Slide 2/11


Background Hubli Dharwad twin cities supply municipal water every 3-4 days • About 114,000 direct water connections in a population of 150,000 households • Bulk supply to the city reduced from 185 to 150 MLD • No information system to inform residents and utility

Applications of WIS 1) Increased certainty on water supply for residents •

Residents informed about water supply 30-120 minutes in advance

2) Validation of supply timings with customer feedback Areas Surveyed

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
