Rainwater Harvesting Techniques:
The accumulation of rainwater from the roofs of buildings can easily take place within cities and towns. All that is needed to gather this water is to steer the flow of rainwater from roof gutters to a rainwater storage tank. Water can thus be stored for future uses.
If you are dependent on collected rainwater and are not attached to a town’s water supply, then the water collected plays a significant role in your life. If you are from the city, then it is feasible to substitute all or, at least, a considerable portion of your fresh water requirements by the capture and storage of rainwater from your roof.
