The quantity of water used depends upon the number of people using the dwelling, how water is used, and maintenance of the water supply system. Average water use in rural households is 75 gallons per person per day. Installing low-use water fixtures along with individual awareness, concern, and conservation efforts can greatly reduce the household water use. Turn off water between uses and fix plumbing fixture leaks. Consider which actions use the most water.
Toilet flushing usually ranks highest.
Low-flow models could decrease water use by more than half. At least consider filling a plastic bottle with water and putting it in the toilet tank to reduce the water required to refill the tank after a flush. The bottle size will vary, but a one-liter drink bottle may be a possibility. There are also commercially available devices available for putting in the toilet tank. Bathing and clothes washing are next in order of water use.
