Restoring Cal Water to Better-Than-New Performance
When first put into production, DOM 294-01 produced approximately 1,200 gpm with 45 feet of drawdown, for a specific capacity of 26.7. Over the next several years, the well was mostly idle for extended periods of time (due to water quality issues), punctuated with periodic pump-to-waste events. By October 2014, during testing with a new pump/motor, the pump/motor broke suction within 1 to 2 minutes of startup. Rehabilitation consisted of WellJet service followed development by airlifting and swabbing. Post-rehabilitation, the well produced 1,200 gpm, with a drawdown of 24 feet, for a specific capacity of 51. This was the design discharge rate, with an overall efficiency considerably better than when the well was new.
