Characteristics of Pump Performance in Major Irrigated Areas of California

Well pump tests (12,876) in three Central California groundwater basins were characterized and described according to their spatial distribution.  The average overall pumping plant efficiency (wire-water, not including column losses and velocity head) was about 56%.  Characteristics such as drawdown, total dynamic heads, kW, and flow rate vary greatly between pumps within and between sub-basins.  This is the first well pump characterization of its type in California, although irrigation pump tests have been conducted for over 70 years in California.  This paper provides a summary of the spatial variation of well pump performance and characteristics.
