A valve assembly for use in aquifer liquid flow control in accordance with one embodiment can be used to deliver liquid to and/or from at least one selected aquifer in a plural aquifer system. In accordance with an embodiment, the valve can be used to route liquid to or from a first aquifer without delivering liquid to or from a second aquifer, or to or from the second aquifer without delivering liquid to or from the first aquifer. As an aspect of an embodiment, the valve assembly can be used to shut off the flow of liquid to both the first and second aq...


1. A valve assembly for use in selectively delivering recharge liquid through one portion of the valve assembly to an aquifer or receiving liquid from an aquifer through the one portion of the valve assembly and selectively delivering recharge liquid through another portion of the valve assembly to an aquifer or receiving liquid from the aquifer through said another portion of the valve assembly, the valve assembly comprising: a pipe section comprising a wall with an interior surface and an exterior surface and a liquid flow passageway through the pipe s...
