Why do we do rainwater harvesting?
Is rainwater harvesting necessary for all regions?
Rainwater harvesting can be beneficial in regions that experience a moderate to high amount of rainfall throughout the year. It may not be necessary in regions that receive low rainfall, as the collected water may not be enough to meet the demand. However, even in such regions, rainwater harvesting can be used as a supplement to other water sources.
