Abstract
A system controls leakage in a pit which contains equipment which uses pressurized hydraulic fluid. A tap communicates with a space holding leaked fluid, and directs leaked fluid to a fluid sump. A pump moves fluid from the fluid sump to a hydraulic fluid recapturing holding tank located outside the pit above a fluid reservoir. Fluid from the fluid reservoir is selectively relocated into the fluid reservoir, which re-supplies the equipment. An electronic control panel located outside the pit interacts with a remote computer to provide a remote user with information concerning operation of the system and to allow the remote user to monitor and control at least certain operations of the system, and which processor also controls operation of the pump and actuating valve. All of the mechanical and electrical equipment of the system is located outside of the pit.
