Pumping data was collected from over 15,000 well and non-well pumps throughout the Sacramento, Salinas, and San Joaquin Valley groundwater basins of California. Each of these basins is divided into a number of subbasins. A map of the general layout is shown below (gray lines outside of basins represent county lines; gray lines inside basins represent subbasins).

Data was analyzed by basin and subbasin for well pumps and non-well pumps. For each pump type, averages were calculated based on:

  • The whole basin
  • Overall pumping plant efficiency (OPPE)
  • kWh/AF
  • Subbasins

General conclusions were drawn for each set of averages, and a final summary of conclusions is given at the end of each pump type section.
