Installing a well on your property that is equipped with effective well pump services will enable users to tap into groundwater which can save you money on the metered water bills. You can also get water butts to collect and store rainwater that you can use to rinse your garden, wash your car, and eliminate the need for sprinklers for your garden.
The washing machine consumes the most water. Upgrade old models to energy star certified washers that require 40 percent less energy. Make sure to run the washing machine for less than half your clothing. An entire load will mean the washing of more clothes all at once, saving water and power usage.
