Domestic water use
Of course some of the most important uses for water are at our homes. Domestic water use is water used for indoor and outdoor household purposes— all the things you do at home: drinking, preparing food, bathing, washing clothes and dishes, brushing your teeth, watering the yard and garden, and even washing the dog.
Water generally gets to our homes in one of two ways. Either it is delivered by a city/county water department (or maybe from a private company), or people supply their own water, normally from a well. Water delivered to homes is called "public-supplied deliveries" and water that people supply themselves is called "self supplied", and is almost always from groundwater.
The majority of America's population gets their water delivered from a public-supply system. This makes sense, as America's population now largely live in urban centers. The trend over the last 70 years is of people moving to urban centers and is reflected in the shrinking numbers of self-supplied people in the Nation.
