If it hadn't been for those corrupt and totally useless bureaucrats and their systems, the Melamchi water would be there in KTM by now...unfortunately that is not the case and i agree with big K that water is a big issue. I have dug few wells in my home to keep up my supplies. There are still plenty of water basins underneath KTM valley - if managed well could provide regular supply. In many case, the issue is not the water, it is the poor management of it and its unfair distribution. But this theory would apply to most things not working in nepal....
