This is really a very important and thought provoking post. You have not only clarified the causes of the problem. You also suggested practical steps for resolution. Indeed water scarcity is not only a problem of supply. It is also of mismanagement, dilapidated infrastructure and inefficient use. Your point of view that water is a precious resource and everyone should play their part in saving it is very insightful. If communities are sensitized and household level rainwater harvesting from rooftops, repairing leaking pipes and curbing unnecessary water usage, this will save water as well as reduce pressure on urban infrastructure. Indeed change is not only possible by relying on the government, but by the responsibility of each individual.
