A bi-directional valve system for an aquifer thermal energy storage system includes a hydraulic control valve fluidly connected to the aquifer pump and pipeline. A control pump is selectively actuated to hydraulically open and close fluid outlets of the hydraulic control valve. When the fluid outlets are closed, a full flow of water can be pumped from the aquifer, or pressure in the pipeline of the system maintained or increased. However, when the fluid pressure needs to be reduced or water reintroduced into the aquifer, the fluid outlets of the hydraulic control valve are selectively opened.
