A water well recharge throttle valve is configured as a hydraulically actuated flow control device 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 eliminate the entrainment of air which may cause air fouling, bio-fouling, and calcite formation with a resultant reduction in permeability of the aquifer. The valve includes a fixed tubular member which is selectively mounted in one of three ways: (1) to the ...
[ What is claimed is:] [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 section, and a lower end for coupling with a flow inhibitor;a plurality of outlet ports in the intermediate section, through which outlet ports the pressurized water flows into the aquifer;a sleeve over at least the intermediate section, the sleeve being movable ...
