How Piramal Sarvajal Is Solving Rural Water Access in India Through Solar Water ATMs

What is the problem?
The Indian government has tried to resolve water access in rural India for decades. Almost all Indian villages have drinking water infrastructure available. Yet 150 million Indians still lack access to safe, affordable drinking water.
Groundwater in several rural areas is contaminated with fluoride, arsenic, iron, or salinity. Surface water is also heavily polluted with agricultural fertilizers and sewage. Piped municipal water in villages is available intermittently.
Rural women and girls suffer the most. Women often walk distances ranging from 2 to 5 kilometers to get water. Worse, the water they bring home is not always fit to drink. The problem isn't a shortage of water, rather the availability of clean water.
What is the solution?
“Piramal Sarvajal,” which means "water for all" in Sanskrit, provides communities with water treatment systems along with automatic water dispensers known as Water ATMs.
Sarvajal’s standard configuration includes a village water purification system that purifies the groundwater using a five-step process, including media filtration, micron filtration, reverse osmosis, and UV filtration.
The purified water is dispensed through a solar-powered, cloud-connected Water ATM. Villagers use prepaid RFID smart cards to draw water as needed from the Water ATM located near their residence.
Each transaction takes place in real-time on a cloud platform, allowing Sarvajal to monitor water quality, system health, and other consumption parameters. However, Sarvajal does not operate the Water ATMs. Rather, it leases its machinery to a local entrepreneur to manage.
What is the business model?
Sarvajal is a mission-driven social enterprise with two revenue streams. Villagers are charged based on the amount of water they use: 30 paise per liter, a fraction of bottled water prices.
The franchise entrepreneur who manages the ATM pays a portion of revenue to the company for leasing the Water ATM. Corporate partners cover the system’s capital costs.
Sarvajal covers its operational expenses with earned revenue and finances capital expenditures with external capital from Corporate partners or government subsidies.
Why is it innovative?
Sarvajal shifted the paradigm of rural water as a service (government brings water for you) to a utility where you collect the water yourself. The Water ATM engineering allows this solution to scale. Each kiosk operates on solar energy, allowing it to function in villages with unstable electricity. Each kiosk is cloud-connected, so the company can control water quality, equipment status, and water consumption rates through the dashboard. Prepaid RFID cards help to avoid handling money every day, which makes running such a rural business difficult. Also, since the local operator is a franchisee and not an employee, it is much easier for Sarvajal to scale its business.
What is the impact?
Based on Sarvajal’s annual report:
765,000+ Daily Beneficiaries: Delivers a reliable, continuous source of safe drinking water to over three-quarters of a million people every day.
2.45+ Billion Liters Dispensed: Distributed an immense cumulative volume of safe, purified drinking water since inception.
1,965+ Active Touchpoints: Operates a vast decentralized network of local purification plants and solar-powered Water ATMs.
300+ Local Entrepreneurs Empowered: Drives economic growth by using a franchise model that turns local citizens into water entrepreneurs.
What needs to improve?
Dependent on Corporate Social Responsibility funding, Sarvajal growth may stall should spending patterns change. Maintaining service quality across 300+ franchises across 20 states is challenging, and a poorly performing franchisee can negatively affect community perception across an entire region. Competition from government programs such as India’s Jal Jeevan Mission seeks to provide piped water connections to every rural household by 2028. If the government succeeds, the need for community water ATMs could decline.
