Rainwater Harvesting: Kerala Says No to Drought

Rainwater Harvesting: Kerala Says No to  Drought

India’s requirement for water is anticipated to be double the supply by 2030.  Whilst the government is taking measures to overcome the water crisis, hundreds of citizens and communities across the country are doing their part by practicing rainwater harvesting.

Kerala witnessed a drought-like scenario soon after the flood of 2018. This was ironic in the context of the ‘water world,’ from which the state had just managed to escape. Undoubtedly, we need to have a sense of guilt concerning our wrong perceptions of development. We can rectify it only by thinking sustainably. Proper rainwater harvesting and management is one of such scientific methods.

The government of Kerala has recently made it mandatory for all new constructions to install a rainwater harvesting system.

Rainwater harvesting is a necessity, not an option

Through proper rainwater harvesting, we can conserve and manage water as per our requirements.

* Rainwater harvesting helps in replenishing groundwater level and improves the quality of groundwater through dilution.

* It is an alternative when surface water cannot meet our demand for water.

* We can use stored water for agriculture and household needs.

* Above all, more dependency on rainwater harvesting means less exploitation of nature.

How?

Rainwater can be collected from the rooftops to lakes. Dams have become a threat at times of heavy rainfall. This was what happened in Kerala. The amounts of water that can be stored in dams crossed the limit and the officials had to open shutters to release the excess water. This intensified the 2018 flood.

By capturing water directly to rainwater tanks or reservoirs, we can drastically cut down our dependence on dams. This can lessen pressure on the existing dams and reduce the need for building new ones.

Similarly, at times of drought, we can use this collected water for daily purpose and irrigation. We can do this by capturing the rainwater and directing the flow of rainwater from roof gutters to a rainwater storage tank. By doing so, water can be collected and used for various purposes.
