Water collected from rooftop water harvesting system was directed into _____.

  1. Ponds

  2. Lakes

  3. Underground tanks

  4. Farms
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

i) In semi-arid and arid regions of Rajasthan almost all the houses traditionally had underground tanks for storing drinking water. They are extremely reliable source of drinking water when other sources are dried up. This is considered the purest form of natural water.

(ii) The tanks can be as large as big rooms.

(iii) The tanks were part of the well-developed rooftop rainwater harvesting system.

(iv) The tanks were built inside the main house or the courtyard giving cooling effect to the rooms in the summer.

 (v) Those tanks were connected to the sloping roofs of the houses through a pipe.

(vi) Rain falling on these roof tops would travel down the pipe and stored in these underground tanks.

(vii) Usually first rain water is not collected to clean the roof top and the pipe.

C Correct answer
Explanation

In the semi-arid and arid regions of Rajasthan, particularly in Bikaner, Phalodi and Barmer, almost all the houses traditionally had underground tanks or tanks for storing drinking water.

A deficiency in ______ for successive years result in serious water shortages. 

  1. Monsoon rainfall

  2. Winter rainfall

  3. Summer heat

  4. None of these
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

In many regions, especially those dependent on agriculture, a deficiency in monsoon rainfall for successive years leads to drought and severe water shortages.

Multiple choice evs receding water table water resources and conservation water conservation and irrigation water a precious resource

Which one is not a beneficial effect of water conservation?

  1. Reduction in water loss

  2. Reduction in water fall

  3. Reduction in waste of resources

  4. All of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Water conservation aims to reduce waste and loss. A reduction in 'water fall' (precipitation) is a natural climatic event, not a beneficial effect of human water conservation efforts.

The component of rainwater harvesting system is

  1. Conduits

  2. Dam

  3. Lake

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
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'.

Identify the types of rainwater harvesting method.

  1. Roof top

  2. Run off

  3. Dam

  4. Both A and B
Reveal answer Fill a bubble to check yourself
D Correct answer
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.
  • Broadly there are two ways of harvesting rainwater. They are Surface runoff harvesting and Rooftop rainwater harvesting.
  • Hence Rooftop and runoff are the types of rainwater harvesting methods.
  • So, the correct answer is 'Both A and B'.

Water scarcity is caused due to:

  1. population growth

  2. water cycle

  3. non-melting of snow

  4. rain fall
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The population is a major cause of water shortage. Water is polluted when industrial wastes are deposited into water bodies thus making it unfit for human consumption. Thus there is a need for water security.

Under or non-availability of usable water is called:

  1. purification of water

  2. pollution of water

  3. rationing of water

  4. scarcity of water
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Scarcity of water is the under or non-availability of usable water. This water presence in the ground is very less and this may sometimes lead to draughts.

  3. distribution of stored water

  4. water supply
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Rainwater harvesting is the process of collection of rainwater from surfaces on which rain falls, filtering it and storing it for multiple uses  'OR' the method of collecting, storing and distributing rainwater for different uses. 

The collected water can be stored for direct use or it can be diverted for groundwater recharge.
