In general, groundwater levels in London vary from 10m to 40m below ground level, reaching their highest point towards the east in such areas as Woolwich and Barking. Without action it had been estimated that the water table would return to its natural level of between 20m and ground level by 2010 and had been rising, according to some estimates, by more that 2 metres per year.
