Construction dewatering in fine soils can be difficult, becausewell yieldsare often low and it is usually necessary to apply a vacuum to assist drainage. Ejector systems are therefore ideally suited to groundwater control in fine soils and have been used increasingly in the UK in recent years. Although their efficiency is low, this is not usually an issue when the flow rate of groundwater is small...
