FAQs on Rainwater Harvesting Video Lecture - Science for Class 6
| 1. What is rainwater harvesting? |  |
Ans. Rainwater harvesting is the process of collecting and storing rainwater for various uses such as irrigation, household chores, and groundwater recharge. It involves the collection of rainwater from rooftops or other surfaces and directing it into a storage system for future use.
| 2. How does rainwater harvesting work? | |
Ans. Rainwater harvesting works by collecting rainwater from surfaces such as rooftops, terraces, or even the ground. The collected rainwater is then directed into a storage system such as a tank or underground reservoir. This stored rainwater can be used for various purposes like watering plants, flushing toilets, or even for drinking after proper filtration and treatment.
| 3. What are the benefits of rainwater harvesting? | |
Ans. Rainwater harvesting has several benefits. It helps in conserving water by utilizing rainwater for various purposes, reducing the dependency on freshwater sources. It can also help in reducing water bills, especially in areas where water scarcity is a concern. Additionally, rainwater harvesting promotes self-sufficiency and provides an alternative source of water during droughts or water shortages.
| 4. How can rainwater harvesting help in groundwater recharge? | |
Ans. Rainwater harvesting plays a crucial role in recharging groundwater. When rainwater is collected and stored in underground reservoirs, it percolates into the ground, replenishing the groundwater table. By allowing rainwater to seep into the soil, it helps in maintaining the natural water cycle and recharging the underground water sources, which are essential for sustaining ecosystems and meeting water demands.
| 5. Is rainwater safe for drinking purposes after harvesting? | |
Ans. While rainwater is generally considered safe for various non-potable uses, such as irrigation or washing, it may not be safe for drinking purposes without proper treatment. Rainwater can pick up contaminants from the atmosphere, roofs, or storage tanks during collection and storage. Therefore, it is recommended to treat rainwater before consuming it, using methods like filtration, disinfection, or boiling. Proper filtration and treatment processes ensure that rainwater is safe and suitable for drinking.
