Question

Briefly discuss why rainwater harvesting is considered an important method of conserving water.

Answer 1

Rainwater harvesting is regarded as an important method in the following ways:

1. The majority of rainwater seeps into the ground, raising the level of groundwater. However, because of concrete covering brought about by urbanization, the soil areas have decreased. As a result, groundwater levels are declining. Due to a lack of groundwater, some areas have experienced droughts. However, by using rainwater harvesting techniques, water can be preserved.
2. Increasing population and urbanisation have increased the demand of water for domestic and industrial use. This is causing shortage of water in cities. Rainwater harvesting provides an effective way to overcome the problem of water shortage.
3. Even on residential roofs, rainwater collection is a simple process to implement. Water can be gathered in wells, tanks, and reservoirs, or tubes can be run straight from roofs to groundwater levels. The water that is gathered and stored underground aids in the replenishment of groundwater levels. We call this recharge of groundwater. Rainwater can be cleaned and prepared for use in industrial settings, as well as for laundry and irrigation. It is simple to conserve water in this way.
4. It can lower water costs, stop flooding and soil erosion, and give communities access to clean, safe water. Because of all of this, collecting rainwater is a simple and efficient method of conserving water.
