The Deep Hand Tube Well (DHTW) is necessarily a crucial option under RRAP implementation. Access to pure drinking water is a pre-requisite in ensuring healthy living around the world. But, in case of project intervened areas, the acute crisis of drinkable water, during disaster and even regular time, is an every-day cry and needs to be addresses properly and on an urgent basis. Nevertheless, this option came as a general output/demand of every CRA, conducted around the southern part of Bangladesh, where salinity intrusion is making the life more difficult over the time.  

With this intervention, CDMP approached to help the southern dwellers (predominantly) having access to improved drinking water source. However, nn improved drinking-water source is defined as one that, by nature of its construction or through active intervention, is protected from outside contamination, in particular from contamination with fatal matter/compounds.
