Odisha Drinking Water Project


Many rivers and lakes are drying up because of climate change. They are also becoming increasingly polluted. An increasing number of people must rely on ground water for drinking.

A large number of wells must be established annually to replace the failing surface waters. Some of the new wells may contain Arsenic, Fluoride, Uranium, Radon, Aluminum, Copper, Cadmium, Barium, Lead, Manganese and other heavy metals and minerals in larger concentrations that will affect human health.

These minerals have always been there. But it has not been a concern as the water was not been used for drinking before when pure surface water was amply available.

According to latest reports, up to 500 million people worldwide suffer from arsenic or fluoride poisoning. Many others are slowly being poisoned by well water containing high levels of other unhealthy natural minerals.

More than one billion people now drink water that is poisoned by natural minerals.

HVR has devised inexpensive, absolutely reliable and robust equipment that will remove all contaminants from water. Just starting to drink pure water will restore the health of millions. A demonstration unit will be installed in Odisha, India, in 2018.

The first demo is sponsored by the Indo-Swedish Rheumatology foundation in Odisha, India

Over half of groundwater sources in India have fluoride above recommended levels. Endemic skeletal fluorosis is widely prevalent and is a major public health problem.

The bone is hardened and thus less elastic. Thickening of the bone structure and accumulation of bone tissue in ligaments and cartilage contribute to impaired joint mobility, impairment of muscles and pain. Chronic
intoxication may cause untimely death. ISRFT (Indo-Swedish Rheumatology Foundation Trust) operates a charity hospital in the town of Balasore in Odisha (www.shakuntalahospital.com).

In a village close to Balasore the whole population shows severe signs of fluorosis, i.e. growth disturbances and discolored teeth in children, joint contractures, pain and premature death in adults. One well serves the school as well as many inhabitants. Water purification at the well could thus be helpful for many people, and especially save school children from intoxication.

If fluoride intake is stopped, the fluoride existing in bone structures will deplete and be excreted via urine. However, it is a very slow process to eliminate the fluoride from the body completely. ISRFT will purify the drinking water in the above-mentioned village and will make a long-term study of the results by analysis of fluoride content in blood and urine as well as by clinical follow-ups.


Research has been conducted at the Royal Institute of Technology (KTH) in Stockholm, Sweden about how to design a sustainable solution for providing pure drinking water to people with poisoned wells. Many engineers, students and scientists have been involved. Masters and Doctoral studies have been completed. Experimental models and prototypes have been built. Feasibility studies have been performed. The final step to commercialize the technology was taken by the group of people below after which the implementation was left to HVR Water Purification AB, a Swedish start-up with close to 4 000 private individuals as shareholders

KTH participates in the project with two Bachelor’s studies and one Masters Study. Here is a kick-off for the two Bachelor’s Studies at the Royal Institute of Technology in February 2018.
