Water Conservation and Management Questions
-
A bucket for collecting excess water
-
A glass for rinsing after brushing teeth
-
A 3 star energy efficient showerhead
-
Repairing a leaking tap
C
Correct answer
Explanation
3-star (or higher) water-efficient showerheads can reduce water usage from 15-20 liters per minute to 6-9 liters per minute, making them the most effective single product for bathroom water savings.
B
Correct answer
Explanation
According to EPA data, the average household loses approximately 13.7% of water through leaks. This statistic highlights the importance of fixing leaky faucets and pipes for water conservation.
-
50-100 litres
-
500-800 litres
-
100-200 litres
-
250-500 litres
B
Correct answer
Explanation
Developed countries have much higher per capita water consumption due to practices like frequent showers, washing machines, dishwashers, lawn watering, and car washing. The 500-800 litre range reflects this high usage pattern. Developing countries typically use much less (50-150 litres per person daily). 250-500 litres would be on the lower end for developed nations.
C
Correct answer
Explanation
Fresh water makes up only about 2.5-3% of all water on Earth, with most of that trapped in glaciers and ice caps. The 2.7% figure correctly represents this small proportion of usable fresh water relative to total planetary water.

400 billion gallons
-
100 billion gallons
-
200 billion gallons
-
500 billion gallons
A
Correct answer
Explanation
Global water consumption estimates vary by source and year. 400 billion gallons (approximately 1.5 trillion liters) is a commonly cited total for daily worldwide use across agricultural, industrial, and domestic sectors.
-
Water that is spilled onto the ground
-
Water beneath the ground surface
-
The bottom part of a lake or river
-
Rainwater that lands on the ground
B
Correct answer
Explanation
Groundwater is defined as water found underground in the cracks and spaces in soil, sand, and rock. It is stored in and moves slowly through geologic formations of soil, sand, and rocks called aquifers.
-
A place to store water.
-
An area of land that drains into a particular lake or river.
-
An area of sandy soil that collects pollutants.
-
Stationary wetlands that act as a sponge.
B
Correct answer
Explanation
A watershed is an area of land where all flowing water (from rain, snow, or springs) converges to a single point before exiting the area - typically draining into a lake, river, or ocean. It's defined by topographic high points that determine drainage boundaries.
-
Wells
-
Canals
-
Tanks
-
River lift system
-
River valley system
D
Correct answer
Explanation
In this system, water is directly drawn from the rivers for supplementing irrigation.
-
It should be ensured that there are no open drains.
-
Chemical waste from factories should be properly treated before its release into water.
-
Proper toilet facilities should be provided to the rural people.
-
Sewage from the cities should be discharged directly into rivers.
-
It should be ensured that there are no leaking sewage pipes.
D
Correct answer
Explanation
This is the correct option as this is not a step that should be taken to maintain sanitation and avoid water pollution. Sewage from the cities should not be discharged directly into rivers. It must be treated and made harmless before its release into the rivers.
-
Storing it again
-
Using it for watering plants
-
Removing the pollutants and reusing it
-
Injecting it into the ground
-
All of the above
C
Correct answer
Explanation
Yes, it is correct. Waste water can be saved by treating it and then reusing it.
-
Sewer
-
Drain
-
Sewerage
-
Sewage
-
None of these
C
Correct answer
Explanation
Yes, it is correct. The network of pipes below the ground for carrying sewage forms the sewerage.
-
Pasture lands
-
Water in wells
-
Roads
-
Canals
-
Public parks
E
Correct answer
Explanation
This is the correct answer as public parks or play grounds etc. in urban and rural areas are de facto accessible to all the people living there. Thus, these are community owned.
-
A cirque
-
Acave
-
A mushroom rock
-
A cliff
B
Correct answer
Explanation
Caves are formed by the dissolution of limestone by groundwater, making them a feature of underground water action. Cirques are formed by glaciers, mushroom rocks by wind abrasion, and cliffs by various erosion processes - none involve underground water.
-
Seas
-
Sewerage
-
Rivers
-
Ground water
B
Correct answer
Explanation
Sewerage is not the destination of treated water.
