A water well recharge throttle valve (1) is configured as a hydraulic actuated flow control device (5) that permits calibrated throttling of water used in Artificial Storage and Recovery (ASR), Salt Water Barrier, Dedicated Recharge and Injection Wells to prevent the free cascading of water and thereby eliminating the entrainment of air which may cause air fouling, bio-fouling, calcite formation with a resultant reduction in permeability of the aquifer.
1. A downhole flow control for use in combination with a recharge well for recharging aquifers, the flow control comprising:a valve configured as a pipe section having an upper end for coupling through the recharge pipe with a source of pressurized water, an intermediate portion, and a lower end for coupling with a flow inhibitor; an outlet section in the intermediate portion, through which outlet section the pressurized water flows into the aquifer; a sleeve over at least the intermediate portion, the sleeve being movable between a first position in whi...
