Rain Water Harvesting: Look towards a better future
The fight of the clean drinking water is increasing day by day. So we have to think wisely to protect and conserve our water resources. There are many techniques to conserve water. Through this hub I am promoting an awareness program to conserve rain water for our daily requirements. Everyone knows about this old technology, but now it is gaining more popularity as the unavailability of fresh water.
What is Rain Water Harvesting?
We all know that harvesting of rain water means collecting of rainwater during rainy seasons for future use. This is an old technology that existed early as third millennium BC. Now many of the nations including India is making strict laws to implement rain water harvesting and also to protect the water resources.
What is the requirement of Rain Water Harvesting?
Why is it important because,
- The available surface water is inadequate to meet our requirements, in order to overcome this we are exploiting ground water by drilling bore wells. Thus the under water level is decreasing.
- Due to rapid urbanization, forests are cleared and thus rain reduced. Thus the infiltration of rain water into the soil decrease and ground water level reduced.
- Infiltration of water is reduced by covering the ground by placing concrete slabs.
If we continue this without considering the importance of rain water harvesting, then we have to fight between us to get water or we have to give our land for a bottle of water.
- Depends more on ground water by digging bore wells.
- Increase in water usage
- Over use of Ground water.
- Destruction of forest land and thus reduction in rain water.
- Reduction in open soil surface area as ground is covered by concrete slabs.
- Due to unavailability of open soil places, infiltration of water is reduced and also quality of water reduced.
- Industrialization causes water pollution.
- Unavailability of better waste water treatment.

Water harvesting is a great way to help curtail your dependence on municipal water to irrigate your landscaping. If you are thinking about constructing some swales, micro-basins, or even rain barrels to capture rainfall, it would be wise to estimate
Techniques for Rain Water Harvesting:
Two main techniques can be adopted for Rain Water Harvesting.
- Recharge to Ground water.
- Storage of rain water on the surface by different methods for future use.
Storage of rain water on the surface is one of the old techniques. This can be done by building underground tanks, ponds, check dams, weirs, tanks etc.
Recharge to ground water can be done by the following techniques…
- Making Pits: These can be constructed for recharging ground water, it’s a traditional method. Make a 1-2m wide and 3m deep pits.
- Dug wells: Constructing dug wells or using already existing wells can be used for recharge ground water. Pass water through filter before putting to dug well.
- Hand Pumps: The hand pumps can be used for recharging the shallow aquifers. A filter can be used to purify water before passing in to pumps.
- Recharge wells and Shafts: Recharging ground water can be done with the help of building wells and shafts. Wells can be constructed with 100-300mm diameter and shafts can be building with 0.5-3m diameter and 10-15 m deep. Choking of wells can be avoided by filter medium.
- Lateral shafts with bore wells: recharging upper and deeper streams can be done by making lateral shafts of 2m wide and 10-30 m long.
Artificial recharge in urban areas:
Recharge of ground water be done with the help of following methods,
1. Recharging through pits, trenches, wells, shafts etc.
2. Collection of rain water on Rooftop.
3. Water spreading.
4. Rain Water collection by making collectors on over bridges.
5. Induced recharge from surface water bodies.
How we can make Roof top rainwater collection:
For making rooftop rainwater collection we have to consider the following factors...
- Rooftop area should be 100sq.m for single stage house and 500sq.m for multi storage building.
- 2000-25000rs can be used for building different collection tanks.
If the rain water is collected about 55cu.m from a single house, then this can be used for 100days for a 5 member family.
Benefits of Artificial recharge:
- Improvement in groundwater levels.
- Improvement in infiltration of ground water levels.
- Improvement in ground water quality.
- Reduce depending on govt: bodies.
- Throughout availability of water.
Benefits of Rain water Harvesting:
- Improve ground water
- No need of paying money for water.
- Throughout availability of water.
- Less vulnerable to pollution.
- Better availability of pure water.
- Little treatment is required for rain water.
- No smell or taste for ground water.
- Fewer burdens for govt. bodies.
- Improve ground water level.
- Improve the flow of water in rivers and streams.
"Always believe that life starts from water and we need the water to continue to live in this beautiful earth…."
So please starts considering implementation of rain water harvesting methods in your place and conserve some water for future
