Study Notes
Rain Water Harvesting
- Rain water harvesting is a method to collect rain water for later use, which occurs naturally in open rural areas.
- In urban cities, a method is needed to capture rain water, such as 'Roof Top Rain Water Harvesting'.
Roof Top Rain Water Harvesting
- Rain water is collected at roof tops (terrace) of houses.
- Collected water is transferred to tanks, pits, or small wells through pipes.
- The collected water should be used for household purposes only after filtration and purification.
Benefits of Rain Water Harvesting
- Supplements water requirements in cities.
- Raises the sub-soil water level.
- Helps in maintaining and increasing greenery in urban areas.
Importance of Rain Water Harvesting
- If rain water is not collected, it flows down to rivers far away through drains and is not available for immediate use.
- Rain water that falls on roads or concrete areas goes into drains.
- Rain water that falls on untreated ground recharges groundwater.
Innovative Water Collection Methods
- Needed to collect and use rain water in different areas.
- Can be used to collect rain water and make it available for use.
