While the world's population tripled in the 20th century, the use of renewable water resources has grown six-fold. Within the next fifty years, the world population will increase by another 40 to 50 %. This population growth - coupled with industrialization and urbanization - will result in an increasing demand for water and will have serious consequences on the environment. Millions of Indians currently lack access to clean drinking water, and the situation is only getting worse. India’s demand for water is growing at an alarming rate  putting increase strain on water resources as the number of people grows.

Though India has many rivers but most of them are coastal or are fed by the Himalayas. The people in the central and western region mainly depend on rainwater and groundwater. However due to unabated use, the level of groundwater has decreased significantly. The quality is worsening in many areas due to contamination with chemicals and many region have high arsenic and flouride content  which cause acute health problems. The only possible solution to this problem is by Rainwater Harvesting .

Most Indian homes dont employ rainwater harvesting or use the roof for other purposes rendering it unable to be used for harvesting. So our project aims not only at providing incentives to them to install rainwater harvesting but our innovation allows them to significantly increase the catchment area by adding our system of retractable folds during the rainfall. We expect that this system will increase the rainwater harvesting capacity of an average home by 75 to 100 % or even more depending on the surrounding available. We want to use sand filters aided with charcoal for decontamination of any pollutants that may be present in the rainwater which can be used by the entire community without depending on electricity for supply of clean water.
