Rooftop Rain water Harvesting
Rooftop rainwater harvesting is a straightforward technique that involves collecting and storing rainwater from a house’s roof for various purposes. The harvested rainwater can be utilized for non-potable household activities, such as watering gardens, thereby diminishing reliance on conventional water sources1. Here are the key components of rooftop rainwater harvesting:
Catchment: The catchment area is the surface (such as a courtyard, terrace, or unpaved/open ground) that directly receives rainfall. It includes flat RCC or sloping roofs, stone roofs, or any other surface that contributes rainwater to the harvesting system.
Transportation: Rainwater from the rooftop needs to be carried down to the storage or harvesting system. UV-resistant water pipes of the required capacity are used for this purpose.
First Flush: A first flush device is employed to prevent contamination of stored or rechargeable water by potential atmospheric contaminants and roof debris. It also helps clean silt and other materials deposited on the roof during dry seasons.
Filter: Filters are used to treat rainwater effectively, removing turbidity, color, and microorganisms. After the initial flushing of rainfall, water passes through these filters.
Rooftop rainwater structures play a crucial role in water management, empowering people to conserve water and nurture democratic routines. By adopting this method, we contribute to sustainable water usage and reduce our dependence on traditional water sources
