A flood defense system includes a perimeter barrier around an asset or zone to be protected and a soak way system disposed sub-surface within the protected zone and designed to collect surface water from within the protected zone. A sump is provided within the protected zone and includes a pump for pumping water from the sump outside the protected zone beyond the perimeter barrier. A series of sensors senses for the presence of ground water inside and outside of the protected zone and within the sump and a control unit coupled to the sensors controls the operation of the pump in order to remove water from the sump at a rate sufficient for preventing, or at least reducing, flooding within the protected zone. A control unit can provide warning of impending flooding. |
