Question

Suggest a solution to the water crisis and explain its advantages.

Answer 1

Rainwater harvesting is the accumulation and storage of rainwater for reuse in-site rather than allowing it to run off. Rainwater can be collected from rivers, rooftops and the water collected is directed to a deep pit. The water percolates and gets stored in the pit. RWH is a sustainable water management practice implemented not only in the urban areas but also in agricultural fields, which is an important economical cost-effective method for the future. Environmental benefits of Rain Water Harvesting:

1. Promotes adequacy of underground water and water conservation.
2. Mitigates the effect of drought.
3. Reduces soil erosion as surface run-off is reduced.
4. Reduces flood hazards.
5. Improves groundwater quality and water table/ decreases salinity.
6. No land is wasted for storage purposes and no population displacement is involved.
7. Storing water underground is an eco-friendly measure and a part of a sustainable water storage strategy for local communities.
