To provide safe drinking water, the European Union is collaborating with many renowned Indian institutes to introduce natural and proven techniques of water filtration techniques and begun a EU-India River Bank Filtration Network. A center for competence on River Bank Filtration has been set up at Indian Institute of Technology at Roorkee and partners such as Uttaranchal Jal Sansthan, Benares Hindu University (BHU), and Centre for Flood Management Studies at Patna have been included as partners.
River Bank Filtraton is a technique that is cost-effective to remove harmful nmicrobes and organic materials and is achieved through using natural filtered groundwater from aquifers hydraulically connected to rivers and lakes. Wells along rivers are naturally filled after filtration and then accessible by people for harnessing drinking water. Experts say that this technique is cleaner than surface river water. Several experimental sites have already been installed at Haridwar, Varanasi, and Patna and experts are studying the results of these experiments. This technique is used extensively in Europe
