Domestic self-supplied water use map, monthly averages for 2020 by watershed

Detailed Description

This map represents the average amount of water withdrawn each month for domestic self-supply use for all subwatersheds (12-digit Hydrologic Unit Codes or HUC12s) in the conterminous United States (CONUS).

Domestic self-supplied water is water used at home that does not come from a public water utility. This can include potable and non-potable water. The most common source of self-supplied water is a well. Less common self-supplied water sources include rainwater captured in a cistern or spring water piped to a home or outdoor faucet. Domestic self-supplied water is used for all home water uses such as watering gardens, drinking water, or household functions.
