Riverbank Filtration

Riverbank Filtration Test Well

Riverbank Filtration Test Well ₁

A Riverbank Filtration (RBF) test well began pumping 20 million gallons of water a day from underneath the Ohio River. The water is drawn through the acquifer, which serves as a natural filter. This provides a much cleaner source of water.₁

Louisville Water completed the Riverbank Filtration Project at its B.E. Payne Treatment Plant in December 2010. The project is unique because Louisville Water is the first water utility in the world to combine a gravity tunnel with wells as a source for drinking water.2

Technology for Filtration at River Bank in Uttarakhand

Department of Sciense and Technology (DST) in partnership with Uttarakhand State S&T council and Uttarakhand Jal Sansthan has set up a cost effective sustainable River Bank Filtration System (10000-60000 lph) using natural aquifer material catering to a population of more than 60,000 people at Augustmuni, Karnaprayag, Satpuli, Srinagar and Gaucher.

The challenge was to tackle seasonal variation in water supply, avoid surface run-off due to geological terrain and address high turbidity and biological contamination. The intervention has resulted in increasing per capita water availability at affordable cost. The quality of water has also improved and users now only need to disinfect the water before filtrationas against coagulation and filtration along with disinfection, required previously.

Drinking water production requires minimal post treatment and costs less than Rs 2 per cubic meter. Riverbank filtration is providing drinking water for five clusters covering 61159 people at in Uttarakhand. The Technology has been developed and demonstrated in the field but not commercialised.
