Water Conservation Quiz: Questions And Answers

1. Why do we need to conserve water?

There is a lot of water.

It is an unlimited resource.

There is a lot of water.

It is a limited resource.

Water is a limited resource because there is a finite amount of fresh water available on Earth. Although water covers about 70% of the planet's surface, only a small percentage of it is freshwater that is suitable for drinking and other essential uses. With increasing population and industrialization, the demand for water is also growing. Therefore, it is crucial to conserve water to ensure its availability for future generations and to sustain ecosystems that rely on it.

2. Which of the following is the least effective method for conserving water in a residential setting?

Installing low-flow showerheads and faucets

Using a dishwasher instead of hand-washing dishes

Watering the lawn during the hottest part of the day

Fixing leaky faucets and toilets promptly

Watering the lawn during the hottest part of the day leads to significant water loss due to evaporation. It is much more effective to water lawns early in the morning or late in the evening when temperatures are cooler and evaporation is minimized. The other options are all recognized water conservation practices that can significantly reduce water usage in a household.

3. A water-efficient irrigation system may include which features?

Drip irrigation.

Rain shut off devices.

Moisture sensors.

All of the above.

Inefficient irrigation systems can waste a great deal of water each month. Look for sprinklers that produce droplets—not mist. Also, systems with rain shutoff devices and moisture sensors reduce excess watering and runoff.

4. "Ensuring availability of water for the future generations" is a:

Strategy of water conservation.

Key activity of water conservation.

Goal of water conservation.

None of the above.

The statement "Ensuring availability of water for the future generations" indicates a long-term objective or aim that water conservation aims to achieve. It highlights the ultimate purpose of conserving water, which is to secure a sustainable water supply for future generations. Therefore, the answer is "Goal of water conservation."

5. How much water is saved per flush with a high-efficiency toilet?

6 gallons.

2.2 to 5.7 gallons.

6 to 8.5 gallons.

10 gallons.

A toilet from 1992 or earlier is probably an inefficient model that uses between 3.5 to 7 gallons per flush. New high-efficiency models use less than 1.3 gallons per flush. That is 60 to 80 % less water.

6. Which of the following uses less water?

Taking a 5-minute shower.

Taking a 5-minute bath.

Both

None

a 5 minute shower uses 10-25 gallons of water. It does not matter how long you spend in the bath tub. It takes 70 gallons to fill a tub.

7. Which of the following water conservation techniques is most effective in reducing water usage in agriculture while maintaining crop yields?

Flood irrigation

Drip irrigation

Furrow irrigation

Overhead sprinkler systems

Drip irrigation is the most effective water conservation technique in agriculture. It delivers water directly to the plant's root zone, minimizing evaporation and runoff. This method ensures that water is used efficiently, reducing overall usage while maintaining or even improving crop yields. Unlike flood or furrow irrigation, which can lead to significant water waste, drip irrigation targets water delivery where it's needed most, enhancing both conservation and agricultural productivity.

8. Which of the following is a way of conserving water?

Leave the tap running while brushing teeth.

Use a hose to wash the car.

Use the washing machine at full load.

Leave the shower running while soaping.

Using the washing machine at full load is a way of conserving water because it maximizes the amount of laundry being washed per cycle, reducing the number of times the machine needs to be run. This helps to minimize water waste and promote water conservation.

9. Easily corrected household water leaks account for what % of the water bill?

8 %

10%

18%

1%

A leaking faucet that drips 1 drip per second can waste up to 3000 gallons of water each year. to test for leaks - read meter before and after a 2 hour period when water is not being used. If the readings do not match exactly, there is a leak.

10. Which one of the following generally accounts for the major use of household water?

Landscaping

Shower

Washing Machine

Dishwasher

Landscaping generally accounts for the major use of household water. This is because maintaining a garden or lawn requires regular watering, which can consume a significant amount of water. Showers, washing machines, and dishwashers also contribute to household water usage, but landscaping tends to have a larger impact due to the frequency and volume of water required for irrigation purposes.
