Riverbed filtration(RBF) system is used to develop ground water and infiltrated water supplies from permeable sand and gravel deposits. RBF plants are constructed with a reinforced concrete caisson that serves as a wet well pumping station. The lateral well screens are projected horizontally into waterbearing deposits from inside the caisson. Riverbed filtration(RBF) is a low-cost and efficient alternative water treatment for drinking-water applications.
