Drinkwell is poised to revolutionize the global water industry by transforming the world's water crisis into entrepreneurial opportunity by using a micro-franchise model to establish local water businesses in arsenic-affected areas. By providing affected villagers with water filtration technology and business tools, Drinkwell taps into the entrepreneurial spirit within these communities to create jobs, generate income, and improve health outcomes. Building off of 200 profitable deployments across India, Laos, and Cambodia through local partners, Drinkwell Systems deliver 60x more water, is 17x more energy efficient, and reduces waste by 7 orders of magnitude compared to Reverse Osmosis, the current best practice. Drinkwell aims to save the 200 million people from drinking arsenic and fluoride-contaminated water from death by giving them a healthier, profitable future.
Mitigating arsenic crisis in the developing world: role of robust, reusable and selective hybrid anion exchanger (HAIX)
Drinkwell's patented Hybrid Ion Exchange or "HIX" line of nanotechnology resins have been consistently removing arsenic and fluoride from groundwater to meet World Health Organization standards in the most challenging regions in South Asia thanks to its unique zirconium-based composition.
Brackish water desalination plants are mostly located inland and must resort to expensive concentrate disposal methods like deep well injection or evaporation ponds. Increasing the recovery of RO process would obviously reduce the volume of concentrate to be disposed of but cannot be implemented due to scaling of sulfate (CaSO4, BaSO4, etc.) and silica (SiO2) resulting in fouling of RO membranes. We have developed a hybrid Ion Exchange-Reverse Osmosis (HIX-RO) process where tunable anion exchange resins can eliminate sulfate precipitation (2) and silica fouling without addition of external regenerants or anti-scaling chemicals.
The World Health Organization reports that the arsenic water crisis, affecting over 200 million people across 70 countries, is the largest mass poisoning in human history (World Health Organization, 2000). Despite millions of dollars being spent, over 48 million people in India and Bangladesh alone are affected by widespread arsenic poisoning due to drinking water drawn from underground sources containing arsenic at concentrations well above the permissible limit of 50 ug/L. In Bangladesh, one in every five deaths occurs due to arsenic-contaminated water (The Lancet, 2010).
Since the 1970s, tens of millions of people in West Bengal and Bangladesh have been at risk of an early death from groundwater containing toxic levels of arsenic.
In Bangladesh alone, 90 % of the nation’s population uses groundwater as their primary source of fresh water, and there are over 77 million villagers in rural Bangladesh whose only water source is contaminated by the toxin. As the population has grown throughout the decades, the problem has gotten worse, and attempts to mitigate the disaster have been unsuccessful.
According to the World Bank, the arsenic crisis, stunts intellectual development, creates gender inequalities, and has already cost the Bangladesh economy US$22.89 Billion in lost GDP due to its debilitating health effects.
Arsenic is a colorless, odorless, naturally occurring metal that is found in dangerously high amounts within the groundwater of South Asia. Long-term exposure to such high levels of arsenic can lead to arsenicosis, an incurable cancer-causing disease.
Despite billions of dollars being spent, 780 million people still lack access to clean, potable drinking water. According to the UN Joint Monitoring Programme on Water and Sanitation, 50% of all water projects fail because communities have not or cannot assume responsibility for maintenance and repairs of water systems. Drinkwell leverages the profit incentive to sustain community involvement from project inception through maintenance and upkeep by using our "Select, Build, Sell, Collect" approach. We operate a network of entrepreneurs that generate an income by selling clean drinking water that can improve the health, wealth, and productivity of the world's poorest populations.
Drinkwell takes waste management very seriously, as the team has personally seen the adverse effects of improper waste management in current solutions that allow for arsenic to leach back into the soil, thereby repolluting the environment. Our system has an EPA-validated waste management process:
This disposal technique, developed and validated under rural conditions, is scientifically more appropriate than dumping arsenic-loaded adsorbents into landfills, which is the typical practice in developed nations.

Drinkwell uses award-winning technology developed by Dr. Arup SenGupta of Lehigh University. The technology has seen 200 successful deployments across Laos, Cambodia, and West Bengal (India) through investment of over $1 million as well as mentorship from the following public, private, and non-profit organizations:
Over the past decade, the SenGupta Research Lab of Lehigh University has partnered with Bengal Engineering and Science University in Bengal, India, and Water for People in Denver, Colorado to install 200 community-based wellhead arsenic removal units in remote villages in West Bengal, India. These systems supply nearly 200,000 villagers with arsenic-safe water. Each village manages the system through a local community-based committee and have been running successfully for several years.
In 2008, the Tagore-SenGupta Foundation was formed to introduce the technology using an innovative school-based business model. The work revealed the enormous potential for scaling a micro-franchise model that spurs entrepreneurship at the individual level, clean water access at the household level, and economic growth and global health improvement at the community level.
Throughout this process, the technology has won countless awards (for a full list of honors and awards please visit the Technology Milestones section).
Drinkwell was established in May 2013 as a part of WIST, Inc., to capitalize on the lessons learned of the over 200 implementations and take advantage of the enormous market opportunity of providing clean drinking water to rural and peri-urban communities that lack access to affordable sources of clean drinking water.
Drinkwell is born from over 30+ years of collective on-the-ground experience in the arsenic water space in India and Bangladesh.
Minhaj Chowdhury (CEO/Co-Founder) has 5 years of experience implementing arsenic projects with the Bangladesh Rural Advancement Committee (“BRAC”), the largest NGO in the world, and Johns Hopkins University. As a Fulbright Fellow to Bangladesh, he researched villager willingness to pay for clean water. His work has been acclaimed by UNICEF, WaterAid Bangladesh, the US Ambassador to Bangladesh, and the Bangladesh Health Secretary, and serves as the basis for Drinkwell's growth strategy. Minhaj has prior experience as a Consultant with Exeter Group where he held roles in product development for state-based health insurance exchanges as well as project management for an operational turnaround of a large non-profit organization with an annual budget of $3B. Minhaj holds a BA in Public Health from Johns Hopkins and has won multiple awards from organizations such as the US State Department, SXSW, and others.
