Water Harvesting In India

Rainwater Harvesting

In India, 50% of water is used in urban areas and 85% of water is used in rural domestic areas. Today we rely on secondary sources of water such as lakes, rivers, ponds, etc and we forget the primary sources i.e Rain.

Rainwater harvest is the collection of rainwater, storing the rainwater in underground tanks and then supply it to many relevant places and some way or the other you are not dependent on the supply of water by the municipal corporation and rainwater harvesting basically done in the monsoon season {end of June to starting of September} and help to store water that can be used for a full year.


need for rainwater harvesting

  • The potable drinking water is in very less in amount to be used by people.

  • Rainwater harvesting helps in recharging the groundwater table and help to stop the reduction in the groundwater table.

  • The runoff rainwater cause soil erosion, if there is rainwater harvesting implemented then rainwater will be saved, and no erosion will be there.

  • We don’t face any shortage of electricity if we have rainwater harvest then if we have plenty of water we won’t face electricity breakdown.

  • Water collected through rainwater harvesting is a pure form of water with no or very few pollutants that can easily be filtered.

Process of rainwater harvesting

Basic Process

  • Rainfall that falls on the roof

  • Move through the pipes

  • Get filtered in the tank

  • Less Cost - It is not necessary to use the rainwater harvesting way we can also use a bucket or other utensils and in that, we can store water can we use in cooking, cleaning, etc.

  • Reduction water bill - It’s said by the government those who are using rainwater harvesting will be getting a rebate in the bill.

  • Promote both water & energy conservation in a way that water is saved and also increase in the generation of electricity as more and more water is getting stored.

  • The one who is installing a harvesting system is easy to install, understand and apply to use.

  • Other benefits could be quality & quantity of water can be improved, decrease the demand for water.

Advantages and Challenges of Rainwater Harvesting

Challenges faced

  • Somewhere or the other we are Dependent on rain for rainwater harvesting.

  • We need skilled personnel to install it.

  • We need to regularly maintain it such as protect it from mosquitoes or other waterborne diseases.


Other countries practice such as:

  • Israel - converting the wastewater to drinkable water through the use of the technique.

  • US- they use a smart water metering technique in which a monitor is installed in the customer house and it will regularly show in which area or through which tap more water is wasted. and the customer is charged according to the wastage of water.

Importance of rainwater harvesting

We should also implement such a technique to conserve water in India. As the requirement for water is very high in India and to preserve water for a large amount of population & various streams such as agriculture and industry we need to save water and best if we start concerting about it from today!
