Rainwater harvesting and rainwater banking are similar concepts but have slight differences.

Rainwater harvesting refers to the process of collecting and storing rainwater for various uses such as irrigation, gardening, and even drinking water. This can be done using different techniques like rooftop rainwater collection systems, rain barrels, or underground tanks. The harvested rainwater can be used immediately or stored for future use.

On the other hand, rainwater banking is a specific type of rainwater harvesting that focuses on collecting and storing rainwater in underground storage facilities. These facilities are often built within urban areas where surface runoff is high, and the collected rainwater can be used to replenish underground aquifers or to prevent flooding.

Both rainwater harvesting and rainwater banking contribute to water conservation by reducing reliance on traditional water sources and minimizing water wastage. They promote sustainable water management practices and can help mitigate water scarcity issues in areas with limited water resources.
