In the indoor water use breakdown, which item accounts for 11%?

• A. Bath - 1%
• B. Other - 3%
• C. Leak - 11%
• D. Washer - 1%

Answer: (C)

Understanding how indoor water use splits among categories helps you know where savings can come from. In this breakdown, the leaks category uses 11% of indoor water, which makes it the largest single contributor among the options. That’s why it’s the best target for reducing indoor water use: small drips and hidden leaks in toilets, faucets, or appliances can waste a lot of water over time, and fixing them often yields quick, meaningful savings. The other categories are much smaller in this breakdown—bath and washer each around 1%, and other about 3%—so they contribute far less to the total indoors, making leaks the priority to address.
