Which water-saving technology utilizes a dual-flush mechanism to reduce water consumption in toilets?

  1. Low-flow toilets

  2. Dual-flush toilets

  3. Composting toilets

  4. Waterless urinals
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Dual-flush toilets offer two flush options, allowing users to choose between a full flush for solid waste and a half flush for liquid waste, reducing water usage.

Multiple choice

What is the primary benefit of using greywater recycling systems in commercial and industrial settings?

  1. Reducing the demand for potable water

  2. Improving the quality of wastewater discharge

  3. Generating electricity from wastewater

  4. Eliminating the need for water treatment plants
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Greywater recycling systems reuse wastewater from sinks, showers, and washing machines for non-potable purposes, such as irrigation or cleaning, reducing the demand for fresh water.

Multiple choice

Which water-saving technology involves using a porous material to capture and store rainwater for later use?

  1. Rain barrels

  2. Cisterns

  3. Aquifers

  4. Water tanks
