Step 1: Collecting RainwaterRooftop CollectionInstall gutters along the edges of your roof to collect rainwater.Ensure the gutters are clean and free from debris.DownspoutsConnect downspouts to the gutters to direct the collected water.Make sure the downspouts lead to the filtration system.Step 2: Pre-Filtering the RainwaterGutter ScreensInstall gutter screens to filter out large debris like leaves and twigs.First Flush DiverterSet up a first flush diverter to remove the initial runoff that may contain contaminants.Step 3: Filtering Rainwater with Sand and CharcoalPrimary FilterConstruct a filter using layers of sand and charcoal.Layer 1: Coarse sand at the bottom.Layer 2: Fine sand in the middle.Layer 3: Activated charcoal on top.Ensure water passes through each layer for thorough filtration.Step 4: Storing Filtered WaterStorage TankDirect the filtered water into a storage tank.Cover the tank to prevent contamination and evaporation.Overflow SystemInstall an overflow pipe to manage excess water and direct it safely away from the tank.Step 5: Recharging GroundwaterInlet to BorewellConnect an outlet from the storage tank to the inlet of the borewell.Ensure the connection is secure and free from leaks.Groundwater RechargeAllow the filtered water to flow into the borewell, aiding in groundwater recharge.Regularly monitor the system to ensure efficient operation.ConclusionBy following these steps, you can effectively harvest rainwater from your house roof, filter it using a sand and charcoal combination, and recharge the groundwater via a borewell. This sustainable practice helps conserve water and supports environmental sustainability. Start implementing rainwater harvesting today for a greener future!
