Riverbank Filtration (RBF) is the influx of river water to the aquifer induced by a hydraulic gradient and it is a low-cost and efficient alternative water treatment for drinking-water applications. The objectives of the project are to study the feasibility of RBF technology, design the pilot system, evaluate the feasibility of the project on socio-economic and environmental impact and transfer the knowledge of RBF technology to the state enterprise organizations, local administrative authorities and other related parties. The project consists of 3 phases, fesibility study (11 months), design and construction (14 months) and operation and maintenance (12 months). Therefore, the specific objective of this paper is to review the basic concepts of the first phase and present some case studies such as Kompahangpet area for detailed study prior the design and construction phase. The target areas are initially focused along the main river courses in Thailand such as Mekong, Ping and Chaophraya Rivers. The study procedure consists of detailed investigations: hydrology, hydrogeology, water demand, suitable socio-economic conditions, and appropriate environments. Mathematical groundwater modeling will be employed to evaluate the suitability of the selected sites. Then we will design pilot system for large scale groundwater resources development to verify that the method could be successfully employed for water resources management and could be further expanded to other areas and extended to other interested parties or organizations in the future.
