Answer 1

Each point: 1 Mark

1. Rainwater harvesting is the accumulation and deposition of rainwater for reuse before it percolates through rocks and reaches the groundwater table. Uses include water for garden, water for livestock, water for irrigation, and indoor heating for houses etc.
2. In many places the water collected is just redirected to a deep pit with percolation. The harvested water can be used as drinking water as well as for storage and other purpose like irrigation.
