A flood defence system (100) includes a perimeter barrier (14) around an asset or zone (22) to be protected and a soak way system (32-34) disposed sub-surface within the protected zone (22) and designed to collect surface water from within the protected zone (22). A sump (30) is provided within the protected zone (22) and includes a pump (170) for pumping water from the sump outside the protected zone (22) beyond the perimeter barrier (14). A series of sensors (102-106) senses for the presence of ground water inside and outside of the protected zone (22) and within the sump (30) and a control unit (108) coupled to the sensors (102-108) controls the operation of the pump (170) in order to remove water from the sump (30) at a rate sufficient for preventing flooding within the protected zone (32). A control unit (108) can provide warning of impending flooding. |
