    Choke or Timer to restrict flow.

    Have choked back to 5 bar 72psi at wellhead. Result significant reduction in electric and no reduction in volume pumped over 24hrs. Pumping about 1 hr on 1 hr off to keep reservoir full. Still pumping at a faster rate than well can recover as flow slows after 30 minutes. When you say choke back...

If I can adjust flow to rate of well recovery in one way or another then I can use the reservoir as...

    Choke or Timer to restrict flow.

    Lowara 16GS40/B 3-phase 4kW pump. This is rated at 8 to 22 m3/hr at 83 to 25 m head. Flexiline riser. 200’ down borehole. Pumping up to 18,000 gallon reservoir where there is a level switch. Pressure at borehole head while pumping is 2bar. We use 80 to 100 m3/day for a couple of farms and...
