Rainwater harvesting is not a new concept, but because municipal water has been plentiful and of good quality, the modern generation has forgotten that many of our forefathers only had rainwater as a source of drinking water. We now have to re-discover the process of harvesting rainwater and apply modern technology and sophistication to supplement the dwindling supply water .A rainwater harvesting system comprises components of various stages – transporting rainwater through pipes or drains, filtration, and storage in tanks for recharge. The rain water is being transported through RCC pipes and being sent to RAIN WATER RECHARCHING PITSthrough desalting chamber. Now question comes why we should go for this project/installation? Rainwater is a clean source of water that can be harvested to solve the water needs as it lacks in contaminants and hard metals, can have good quality water in a cost-effective manner and the main ecological benefit offered by the use of rainwater collection systems is the reduction in this use of mains water which means that less water will need to be artificially drawn from the environment, a supply that is best used for drinking, bathing and cooking as well for commercial purpose.
