NextDrop is a social enterprise that collects and shares water delivery information with city residents and water utilities companies. NextDrop was launched in 2010, in Hubli-Dharwad, twin cities in the southern state of Karnataka in India. Urban Indians have mobile phones, yet access to water is still a challenge. The nearly 1 million people of Hubli get water only every three to five days, for about four hours a day. Using a Smart Water Supply Message Service, Next Drop helps bring water information more transparently to more than 25,000 subscribers by sending them an SMS letting them know when water services will be available in their area that day. NextDrop has expanded its operations to Bangalore, Karnataka’s capital.
