You think you can read, I thought you could. ;) Because I specifically mentioned quot: taken than the leadership is provided ...

and that implies all kinds of leadership. Helping to organize, management, help of qualified engineers, consultations and their services, overseers in the field, and/or training specialists. It's not that it is a rocket science, and we are not talking about skyscrapers. Any body can be a builder after some explaining, if we are talking about single store simple hause with running watter, sewer. And anybody can dig and lay pipes. Hell, they already had ramp, lever, clay brics, stone blocs, ropes, paper, maths, and even a wheel there, more than a 5 thousand years ago. More than 2 thousands years ago they already had there a water wheel, pipes and other water technologies. It is not that a rocket science is needed to develop the enviroment. It can be needed if we want to do it fast, labour and economicaly efective, but that is not a case here. We are talking about supported people – it's not that they use their time efectively now or will lose something by taking two hours per day to improve their enviroment themselves.
