[ 16] Water quality standards for surface waters vary significantly due to different environmental conditions, ecosystems, and intended human uses.
The study found that about 53% of total average household water use, or more than 192 US gallons (0.73 m 3) per household per day, was used for landscaping and other outdoor uses. Meanwhile, indoor use accounted for more than 170 US gallons (0.64 m 3) per household per day. The most in-home water consumption is toilet flushes, using 20% of the ...
