1)
Public supply water use: water withdrawn by public and private water
suppliers that furnish water to at least 25 people or have a minimum of 15
connections. 2) Self-supply water use: Water withdrawn from a groundwater or
surface-water source by a user rather than being obtained from a public
supply. 3) USGS did not provide estimates of residential use from public
supplies in 2000. This value was estimated based on the residential portion
of public supply in 1995 and applied to the total public supply water use in
2000. |
