Complete answer:
Rainwater harvesting is a basic method of capturing and deploying rainwater for further use. This is an increasingly important form of water conservation in apartments and gated complexes. It's common because it can result in big savings and is easy to implement.
For eg, in Panchsheel Park Colony, Delhi, a group of 1,000 residents pooled in Rs. 800 per flat in June 2004 to develop a rainwater harvesting system. Today, more than 170 million litres of water are harvested annually – and this is Delhi's inadequate rainfall.
Rooftop Rainwater harvesting is the cheapest and most reliable method of harvesting rainwater for apartments, because it is cheaper and if implemented effectively, helps to increase the groundwater level of the city. This is a rainwater catching device where it falls.
In this process, the roof becomes a catchment area, and rainwater is collected from the roof of the house, which can either be stored in a tank or redirected to an artificial recharging device.
The semi-arid and arid regions of Rajasthan, primarily in Bikaner, Phalodi and Barmer, have introduced these systems of harvesting. This system is known as tankas in Rajasthan. Nowadays in western Rajasthan, the tradition of rainwater harvesting on the rooftops is on the decline, as a lot of water is available due to the perennial Rajasthan Canal, although some houses still keep tanks because they don't like the taste of tap water.
The given options are as follows.
Punjab is not the state using roof rainwater harvesting on an extensive scale. Thus, option A is not the right answer.
Delhi is also not the state that uses roof rainwater harvesting on a great scale. Thus, Option B is not the right answer.
The State which uses roof rainwater harvesting largely is not Haryana. Hence, Option C is not the correct option.
The state using roof rainwater harvesting on an extensive scale is Rajasthan. Thus, Option D is the right alternative.
Therefore, the correct answer is B
Note:
The average Indian household consumes 350 litres of water every day.
Tamil Nadu is the first state in India to make rooftop rainwater harvesting structures mandatory for all homes throughout the state.
At present, rainwater harvesting in Pune is compulsory for every new housing company to be licenced.
