I recall that there was a new water tower under construction in the old U2 area in the latest DLR-commissioned map. There is another new water tower adjacent to the original tower. It is visible in both Bing and Yahoo maps. Google Earth still has "our" image, so you can only see the pads for the new tower's legs and pipe.
