A system for controlling one or more borehole pumps to enable pumping-on-demand is described. The system uses a computerized controller which, in combination with sensors, monitors and controls the activity of the pump, thereby controlling fluid in the borehole. The system is continually in one of three modes, the monitoring mode, the pump mode, and the recovery mode. Within each cycle of modes, the system performs multiple checks on the apparatus involved. The data obtained during the check is stored in appropriate databases as well as checked against predetermined norms. In the event of a malfunction within the apparatus, or other supervised and/or monitored functions, the system can activate a notification system, such as a centralized monitoring facility. A pump is disclosed with a fluid sensor to detect the presence of fluid and transmit this presence to the computerized monitoring system. A slug sensor notifies the computer of the beginning and end of a predetermined quantity of fluid. An exterior housing with a lightning protector can be placed over the borehole to contain the monitoring computer and associated read outs. At least one shunt valve is affixed along the propellant and return lines inline to accommodate accumulation of fluid. A receiver/separator tank has a separator member to separate the gas from the fluid.

[ What is claimed is:] [1.] A pump for removing fluid from boreholes based on the fluid achieving a predetermined level, said pump having:a. an elongated pump housing, said elongated pump housing having an interior, an exterior, a first end and a second end;b. an inlet chamber, said inlet chamber being adjacent said second end of said pump housing, said inlet chamber having multiple fluid inlets to permit fluid to enter said inlet chamber;c. a valve system, said valve system extending from said second end of said pump housing into said inlet chamber, said valve system enabling one way fluid flow between said pump housing and said inlet chamber to enable said fluid to flow from said inlet chamber into said pump housing during a filling mode and preventing said fluid from exiting said pump chamber during a pumping mode;d. a propellant line, said propellant line having an outlet entering said housing proximate said first end and a compressor connected to an inlet of said propellant line to send propellant into said propellant line;e. a fluid return line, a first end of said fluid return line extending into said pump housing through said housing first end and a second end extending into a fluid storage area;f. a fluid sensor, said fluid sensor detecting the presence of fluid within said pump chamber,wherein fluid enters said inlet chamber and is forced by hydrostatic pressure into said pump housing, said fluid rising until said fluid sensor activates said propellant, said propellant forcing said fluid through said fluid return line into said storage area.
