Bansi Dhar Yadav of Pacheri Khurd in Buhana tehsil of Rajasthan’s Jhunjhunu district is mostly confined to a chair these days. It started about 10 years ago as a pain in his lower back. The pain would steadily increase by the day, until one day when he tried lifting something and couldn’t. “I began to get numbness in my fingers, and soon it spread to my entire body,” the 63-year-old recalls. His younger brother had died after similar symptoms, so, in 2006, Yadav’s son took him to Delhi. After an MRI scan that showed nerve compression, the doctor said it was the increased fluoride level in the water that was causing his problems. “I couldn’t move or eat food or even turn. I tried many treatments, including Ayurveda and yoga in nearby Sikar, but nothing seemed to work,” says the former forest contractor. He admits that since Sarvajal brought its purified water system to nearby Bagar in 2008, there has been an improvement. “I can now walk for a few metres. Earlier, someone had to help with everything.”
Against a normal acceptable TDS (total dissolved solids or impurities) level of 50-150 ppm for packaged or purified water, TDS levels in Pacheri’s ground water have been at 2,500-3,000 ppm, according to a Sarvajal officer. Mahendra Singh, 51, and Raj Singh Yadav, 53, together run the local franchise for Sarvajal at Pacheri Khurd. They sell purified water at 25 paise a litre, less than the 30 paise per litre price stipulated by the company. “That’s what it costs us. My objective was to do social work,” Singh says of his decision.
“Water and health linkages are not easily understood in rural areas,” says Sarvajal COO Anuj Sharma. He points to the presence of bacterial contaminants as well as chemicals such as arsenic and fluoride due to agricultural and industrial pollution. “These are hard-to-remove chemicals and cause irreversible damage. Prevention is the only cure,” he says, adding that it takes time to convince villagers of the dangers of contaminated water and gain acceptance for water projects. “You can fall sick in one day, but the positive effects take time to show.”
Started with a rural focus, Sarvajal now aims to replicate its hub-and-spoke model with a plant and dispensing machines — water ATMs — in urban areas as well, to address limitations with traditional piped water supply in serving the growing population in and around cities. It also works with other coporate organisations by installing filtration units in corporate campuses and for their CSR activities. Sarvajal’s project in Savda Ghevra, a resettlement colony near the Haryana border in the western fringes of Delhi, is “India’s first decentralised drinking water tender in an urban area,” says Sharma. With a source water TDS of 1500-1800 ppm, Sarvajal’s service, which started in 2013, already has over 400 paying members buying water from its 15 water ATMS here.
Like Saravajal, Waterlife, too, operates RO-based water purification systems in rural areas of Kerala, Andhra Pradesh, Karnataka, Maharashtra, Rajasthan, UP, Bihar, Jharkhand and West Bengal. It also works in the slums of Puducherry, Bengaluru, Ranchi and Kolkata. Funded by Aavishkaar and Matrix Partners, Waterlife was started in 2006 by three senior corporate executives — Sudesh Menon, formerly GE’s South East Asia head, and Mohan Ranbaore and Indranil Das from Xerox.“The key was the business model, not so much the technology; how to make it work in rural areas and execute in difficult conditions,” says Menon. “We have been profitable from the first year of operations.”
That’s been possible because Waterlife partners with local governments to fund the cost of its filtration systems, which cost between ₹2 lakh and ₹20 lakh.It has over 100 projects in operation where it helps set up community water stations and units for treatment of water for fluoride, nitrate and other high TDS contaminants, which reach out to over 4,000 villages with population between 500 and 20,000. In remote areas, Waterlife provides contamination removal units that can be attached to handpumps.
Not all drinking water initiatives are capital intensive. Spring Health is creating an alternative option through the simple and basic process of chlorination. Spring Health is part of Windhorse International, founded by US-based social entrepreneur Paul Polack. It is funded by a group of investors, including First Light Ventures, Acumen Fund (which had invested in the pilot stage and has now exited), Calvert Fund, Phil Friedmann Foundation, Chris Goggin, Mal Warwick, Rianta Capital and Stone Foundation, who have brought in $550,000 to the venture, so far. The project is spread across 107 villages in six districts of Odisha, where drinking water is sold at 40 paise per litre. After months of testing, the commercial rollout for Spring Health began in June 2013. The franchisee, usually a popular kirana, mobile or medical store, is signed on for two years. “In the past four months, we have added 73 villages, averaging around one village a day,” says Spring Health CEO Kishan Nanavati.
Spring Health purifies water removing bacterial contamination using chlorination. “We are not in a position to address chemical and mineral contamination, so we look at water table depth of not more than 30 ft,” points out Nanavati. The water is tested at government-approved labs for pH level, presence of iron, nitrates, sulphur, fluoride, arsenic and bacterial contamination before it is considered for use. At the franchisee’s location, the water runs through two filters into a storage tank above, where it is treated with chlorine oxidants and tested before being made available for drinking. Spring Health’s team also carries out random tests at point of consumption in customers’ homes.
Spring Health works with franchisees on a staggered revenue share plan. From launch to reaching 1,250 litres, it makes 75% of the revenues generated from sale of the chlorinated drinking water. Once the franchisee crosses 1,250 litres and up to 2,000 litres, the share is 50:50. Over 2,000 litres of water sold, the franchisee makes 75% of revenues generated.
The rural market has its own challenges, though. Caste considerations can be a trigger point. To avoid any conflict between upper and lower castes (who are often not permitted to share common water resources), Spring Health started home delivery of water to the Dalit households in one village. The other communities then promptly demanded home delivery for themselves. Today, 95% of the water is delivered at customers’ homes. The jerry can stays with the customers, reassuring them that no one else has touched the water. For the company, it is a time-saving move, since customers are responsible for cleaning their own jerry cans.
