What we have learnt
- Rainwater harvesting involves various components including gutters, first-flushing devices, and filters to ensure clean water collection.
- Groundwater can be recharged through diverse structures like recharge pits and trenches, facilitating percolation of rainwater.
- Watershed management is crucial for sustainable resource utilization, minimizing ecological degradation, and addressing socio-economic impacts of displacement.
Key Concepts
- -- Gutters
- Channels around a sloping roof that collect rainwater and transport it to a storage tank.
- -- Filtration
- The process of removing suspended pollutants from harvested rainwater using media such as sand, gravel, and charcoal.
- -- Watershed
- The land area that drains water under gravity to a common outlet, crucial for water management and ecological stability.
- -- Groundwater Recharge
- Methods employed to facilitate the percolation of rainwater into underground aquifers for sustainable water use.
- -- Global Warming
- The increase in Earth's average temperature due to human activities, significantly impacting climate and environmental conditions.
