Rain Water Harvesting : Expert bite on AIR with Environmentalist SD Virendra, ITDC India Epress

रैन वॉटर हार्वेस्टिंग सड़क पर साइकल चलाने जैसा सरल है, यह वैज्ञानिक टूल अवश्य है, परंतु उसे समझना एक्ज़िट पोल से भी सरल है। Green Donor Series on All India Radio Sept 19 - Mother Nature, My promise. Episode 2

वर्षा जल संचयन वर्षा के जल को किसी खास माध्यम से संचय करने या इकट्ठा करने की प्रक्रिया को कहा जाता है। विश्व भर में पेयजल की कमी एक संकट बनती जा रही है। इसका कारण पृथ्वी के जलस्तर का लगातार नीचे जाना भी है। digital tools is useful. For instance, to detect if a region has a high rainwater harvesting potential, rainwater-harvesting GIS maps can be made using an online interactive tool, or, to estimate how much water is needed to fulfill a community's water needs, the Rain is Gain tool helps. Frankfurt Airport has the biggest rainwater harvesting system in Germany. The system helps save approximately 1 million cubic meters of water per year. The cost of the system was 1.5 million dm (US$63,000) in 1993. This system collects water from roofs of the new terminal which has an area of 26,800 square metres. The water is collected in the basement of the airport in six tanks with a storage capacity of 100 cubic meters. The water is mainly used for toilet flushing, watering plants and cleaning the air conditioning system.[ Government to 3D map aquifers in all villages it is a way to capture the rainwater when it rains, for later use. You, me and everybody! It will not only provide you with water in times of acute water shortage, but will also recharge the groundwater and increase its level. Volume of water harvested = 100 x 0.6 x 0.7 = 42,000 litre what: Rainwater harvesting will improve water supply, food production, and ultimately food security. Who: Water insecure households or individuals in rural areas will benefit the most from rainwater harvesting systems. How: Since rainwater harvesting leads to water supply which leads to food security, this will greatly contribute to income generation Reasons for ground water depletion • Increasing demand of ground water • Withdrawing more than recharge • Reduction of recharge area due to buildings, paved paths and roads • Diminishing surface water bodies • Uncertain rainfall Techniques to improve groundwater through Rainwater Harvesting • Creation of recharge pits, trenches and shafts in building premises, open space, parks and along roads. • Use of existing dry wells as recharge structures. • Rooftop and road top rain water should be channeled into recharge structures. • Protection and conservation of open areas, parks and surface water bodies.
