The Water Witch is a versatile vessel, best described as a floating 'JCB' or bulldozer, which has been developed for marine clean-up operations. It was first developed in the early 1960's, when the British Port of Liverpool was choked with rubbish which was then trapped within the dock system. There are now 69 Water Witch Vessels in operation for the major ports of the world including Hong Kong, New York, Singapore, Cape Town and London.
