  • Question
  • Which one of the following methods is not suitable for urban rainwater harvesting?


  • Options
  • A. Rooftop recharge pit
  • B. Recharge wells
  • C. Gully plug
  • D. Recharge trench

  • Correct Answer
  • Gully plug 

    Explanation

    In urban areas, rain water available from roof tops of buildings, paved and unpaved areas goes waste. This water can be recharged to aquifer and can be utilized gainfully at the time of need. In areas where the surface soil is impervious and large quantities of roof water or surface runoff is available within a very short period of heavy rainfall, the use of trench/ pits is made to store the water in a filter media and subsequently recharge to ground water through specially constructed recharge wells.

    Gully plugs are built using local stones, clay and bushes across small gullies and streams running down the hill slopes carrying drainage to tiny catchments during rainy season.It is applicable only in rural areas.
