Abstract: Embodiments of the disclosure provide a method and system for removing water build-up in a hydrocarbon storage tank. An oil-water interface sensor is located in the hydrocarbon storage tank and includes a first probe and a second probe. The first probe is located at a bottom portion of the hydrocarbon storage tank. The first probe generates a first input data stream. The second probe is located above the first probe. The second probe generates a second input data stream. The first and second input data streams are processed to determine a vertical displacement of an oil-water interface, which is compared against a predetermined value. An output data stream responsive to the comparison is generated including instructions to maintain a controllable valve either in an open position or in a closed position.
