JB Rainwater Harvesting is the leading rainwater harvesting company in India. We are committed to providing the best possible service and products to our customers.
Rainwater harvesting (RWH) is the collection and storage of rain, rather than allowing it to run off. Rainwater is collected from a roof-like surface and redirected to a tank, cistern, deep pit (well, shaft, or borehole), aquifer, or a reservoir with percolation, so that it seeps down and restores the ground water. Dew and fog can also be collected with nets or other tools.
Rainwater harvesting is one of the simplest and oldest methods of self-supply of water for households, having been used in India and other countries for many thousands of years. Installations can be designed for different scales including households, neighborhoods and communities and can also be designed to serve institutions such as schools, hospitals and other public facilities
Monsoon is the prime time where 90 percent rainwater is showered. In India Monsoon is between June to September. Therefore it is the time where most of the water can be conserved and preserved. The right action taken to save water at this time for summer can lead to the greatest results of saving the maximum amount of water.
