The system of harvesting water from rooftops is useful mainly for drinking water purposes. In this system rain water falling on the roofs can be collected through a system of pipes and semi circular channel of galvanized iron or PVC and is stored in tanks in a suitably sized storage tank for providing sufficient water for reasonably long duration. The package of Rainwater harvesting provides a system of pipes for collecting rainwater from roofs and a 3000 liters Ferro Cement Tank for each household. The choice of Ferro cement for tank construction is guided by consideration of optimizing cost and performance characteristics. If cheaper options with equal strength and longevity are available elsewhere these can be adopted after due consultation with the beneficiaries.

If the present capacity of the tank is found inadequate and necessity for larger capacity tank is subsequently felt for the villagers who find the technology suitable, another storage tank of similar or slightly larger capacity (5000 Ltr.) can be provided. Rainwater harvesting from rooftops is most suited in the areas of severe water scarcity. e.g., absence of potable water source in the village, nearest water source being far away or drudgery involved in bringing water in hilly areas or other difficult terrains.
