Drinkwellsystems

Market position

Drinkwell positions itself as a lower-cost alternative to reverse osmosis for decentralised groundwater treatment in South Asia, emphasising regenerable media, government and multilateral backing, and scale of deployment. It reports 3.02M+ people served, 700+ treatment plants deployed and 2.5B+ litres processed, and is described as being in a mass roll-out/expansion stage.

Regenerable, reusable ion-exchange media targeted at specific contaminants rather than membrane-based reverse osmosis, claimed to cut lifecycle costs by about 70%, reduce waste by around 95% and lower energy consumption. The combination of locally regenerable filtration with a micro-franchise operating network and utility co-financing is presented as enabling decentralised scale where utilities supply land, water and power and Drinkwell supplies equipment at no upfront cost.

Technology

HIX-Nano, a patented hybrid ion exchange nanotechnology, uses multi-stage ion exchange to remove arsenic, fluoride, phosphate, uranium, lead, iron, nitrate and other heavy metals at the molecular level while reducing TDS and hardness. The media is fully regenerable and reusable, reducing filter waste and operating costs. The company reports 99.9%+ contaminant removal, compliance with WHO standards, 70% cost savings and 95% waste reduction versus reverse osmosis; third-party material cites claims of 60x more water delivered, 17x less energy consumed and seven orders of magnitude less waste than reverse osmosis. Delivery hardware spans household filters, water ATM dispensing booths with prepaid card payment, and piped municipal systems.

Go-to-market

Drinkwell sells through public-sector and institutional channels — partnerships with municipal water utilities and government agencies, NGOs, and multilateral and bilateral donors — using structured PPP arrangements and turnkey project delivery. At the community level, distribution relies on a micro-franchise network of local operators who run installations and serve end users directly.

Government bodies and municipal water utilities (such as Dhaka WASA), NGOs, multilateral and bilateral development institutions, and households and institutions in arsenic- and fluoride-affected, largely low-income communities in Bangladesh and India.

Geography

Headquartered in the United States, with a base in Dhaka, Dhaka Division, Bangladesh. Operations are concentrated in Bangladesh and India, including arsenic mitigation work in West Bengal, with deployments through local partners also reported in Laos and Cambodia. Employees are spread across Asia and North America.

History

Drinkwell was founded in 2013. By 2018 it was expanding turnkey decentralised water purification systems across arsenic-contaminated communities in Bangladesh, with a focus on approximately three million low-income residents of Dhaka who otherwise rely on unsafe or illegal water sources; the same year ADAP Capital led an investment round. As of April 2020 the company employed around 50 people, was based in the US and operated in Bangladesh and India. In 2023, Dhaka WASA (DWASA) announced a collaboration with Drinkwell to implement a water supply project. The company's site lists an ASSOCHAM National Water Award in 2025 and, in 2026, a World Economic Forum Social Entrepreneur of the Year recognition, inclusion in the Meaningful Business MB100 list, and an Asian Development Bank investment loan partnership tied to a $138M sovereign loan for safe water access in Bangladesh.

Risks & controversies

Performance and cost-comparison figures such as 99.9%+ removal, 70% cost savings, 95% waste reduction and multiples versus reverse osmosis are company claims. The business model depends on utility and donor co-financing, regulated water tariffs and limited end-user ability to pay, and on long payback periods typical of water infrastructure. Employee, revenue and industry classification data from aggregator listings are estimates and internally inconsistent.
