  1. Conduits

  2. Dam

  3. Lake

  4. None of the above

Show answer
Correct Option: A
Explanation:
  • Rainwater harvesting is the collection and storage of rainwater for reuse on-site, rather than allowing it to run off. These stored waters are used for various purposes such as gardening, irrigation, etc.
  • The components of the rainwater harvesting system include  Catchments, Coarse mesh, Gutters, Conduits, First-flushing,  Filter, Storage facility.
  • Conduits are pipelines or drains that carry rainwater from the catchment or rooftop area to the harvesting system. Conduits can be of any material like polyvinyl chloride (PVC) or galvanized iron (GI), materials that are commonly available.
  • Hence Conduits are the component of the rainwater harvesting system.
  • So, the correct answer is 'Conduits'.
