Country Gets First River Bank Filtration System
Published on by Water Network Research, Official research team of The Water Network in Government
The Uttarakhand Jal Sansthan is Going to Set up India's First River Bank Filtration System, a New Low-cost Water Supply Arrangement
The system will be set up in places where the water supply lines were ravaged in last year's flash floods and the hilly areas where the ground water is too low.
The Asian Development Bank is funding the Rs 5 crore project. Karnprayag and Gowchar in Chamoli district, Srinagar and Satpuli in Pauri district, Agasthamoni in Rudraprayag, Haridwar and Uttarkashi have been selected for RBF. The system is widely used in foreign countries but in India it will be started from this year, with Uttarakhand being the first state to introduce it in a full fledged manner.
"We in India were unaware of RBF technique. Uttarakhand is the first state to start work in this regard and hopefully other states will follow."
Two major reasons cited by the UJS to implement this system are high geographical variation in some regions and unstable water tapping systems. "The lowest areas are about 200 meters above the sea level, whereas the highest inhabited areas are more than 3500 meters above the sea level. There are steep slopes, valleys, high ridges, among others. Another major challenge is that because of the steep slopes of the hills, the catchment area created by rain water is very large. This, in turn results in a change in the course of water from season to season. The changing course of water leaves the water tapping structure useless and hiders the supply of water," said PC Kimothi, general manager, UJS.
He added, "Valley fills are abundant in Uttarakhand and that is what gave us the idea to set up the RBF system as these valleys have formed over a period of hundred years and the hydraulic materials act as natural filters."
