Rooftop Rain Water Harvesting
Rooftop Rainwater Harvesting is a sustainable method that involves collecting and storing rainwater from building roofs. Here are the key components and benefits of rooftop rainwater harvesting:
Components of Rooftop Rainwater Harvesting:
Catchment: The catchment area is the surface (such as a courtyard, terrace, or open ground) that directly receives rainfall. It includes flat RCC or sloping roofs. Rainwater from this area contributes to the harvesting system.
Transportation: To carry rainwater from the rooftop to storage or harvesting systems, UV-resistant water pipes or drains are essential.
First Flush: A first flush device prevents contaminants (from the atmosphere and roof) from entering the stored or rechargeable water. It also helps clean silt and other deposits from the roof.
Filter: Filters effectively remove turbidity, color, and microorganisms from rainwater after the initial flushing1.
Benefits of Rooftop Rainwater Harvesting:
Water Availability: Harvested rainwater can be used for non-potable household activities such as garden watering, toilet flushing, irrigation, and laundry washing.
Reduced Dependency: It reduces reliance on traditional water sources, especially during water scarcity.
Groundwater Augmentation: Properly implemented rooftop harvesting helps augment groundwater levels in the area.
Soil Erosion Control: By capturing rainwater, it minimizes soil erosion.
Quality Improvement: Harvested rainwater is often softer and cleaner, leading to less consumption of washing and cleaning products.
Environmental Impact: Rooftop rainwater harvesting contributes to sustainable water management and reduces flooding of roads
