Rainwater harvesting MCQ - Practice Questions with Answers

Tamil Nadu is credited as the first Indian state to make rainwater harvesting structures compulsory for houses, especially through its early 2000s municipal and state-level measures. The rule was meant to recharge groundwater and reduce urban water stress. Rajasthan faces severe water scarcity, but it was not the first state to impose this house-level compulsory requirement. Gujarat has important water-conservation programmes, yet this specific first-state distinction is not attached to it. Odisha also has rainwater and watershed initiatives, but not the pioneering compulsory-household rule asked here.
