Unlocking the Potential of Rainwater Harvesting Practises in Bangladesh

Due to high salinity in surface and groundwater and natural arsenic pollution, people in the coastal region of Bangladesh, are facing water crisis in many areas and are looking for alternatives. In Bangladesh coastal region rainfall in the monsoon season is abundant, but almost absent during the dry season, leading to water scarcity for households and farmers. To address the water crisis in this region rain water harvesting practises (or 3R, recharge, retention and reuse) are often thought as a potential solution to enhance the availability of water. RAIN, with funding of the WASH Alliance International, initiated an in-country study to understand the context of current water supply in the coastal region, to identify main challenges in implementation of the 3R practices, the benefits of such practices and the potential for scaling up of successful practises.


RAIN, in cooperation with Bangladesh University of Engineering and Technology (ITN-BUET), facilitated an expert consultation workshop in Dhaka on January 10. In the workshop the results of the research on the potential of rain water harvesting practises were discussed. This workshop was scheduled after completing a desk study and field visits in the coastal regions of Bangladesh. The workshop was participated by partners of WASH Alliance International as well as other organizations implementing WASH in coastal areas. Academicians, researchers and experts having experience of working on RWH practises in the coastal region also attended the workshop and shared their feedback on the research findings. In a presentation existing local 3R practices and the results of a FIETS sustainability assessment of these practises were shared. After the presentation participants shared their opinion on challenges and opportunities regarding up-scaling of successful practises. The recommendations from the participants will be addressed in the final version of the research report.

RAIN is a brand of Aidenvironment, setting up programs and projects focusing on rainwater harvesting and 3R techniques.
