Answer 1

The correct option is D This technology can be further improved by removing W and Y as they reduce the amount of rainwater reaching the storage well.

In the sandier tracts, the villagers of the Thar Desert had evolved an ingenious system of rainwater harvesting known as kundis the local name given to a covered underground tank, was developed primarily for tackling drinking water problems. The rainfall data collected showed that areas with 100 mm of rainfall can use the kund system effectively. Even if the kunds do not collect sufficient water they can be used as water reservoirs which can be filled by transporting water through water tankers.
