Which of the following is considered a part of average residential water usage?

• A. Recycling
• B. Flushing toilet
• C. Swimming pool
• D. Electricity generation

Answer: (B)

Flushing a toilet is considered a part of average residential water usage because it represents a primary way in which indoor household water is consumed. Toilets account for a significant portion of total water use in a home, often totaling around 24% of the average residential water use. This statistic highlights how everyday activities, such as using toilets, contribute to overall water consumption in residential settings.

In contrast, options like recycling, swimming pools, and electricity generation do not reflect typical daily water usage for most households. While swimming pools can increase water demand, they are not part of the average daily water usage like toilets are. Recycling may involve water use, but it is not a direct part of water usage as it pertains mainly to resource management rather than consumption. Electricity generation refers to industrial processes that typically take place outside residential water use calculations. Hence, focusing on the utility of toilets within homes makes the answer clear in the context of average residential water usage.
