Groundwater is without doubt the greatest natural cause of problems in civil engineering construction. Dewatering is therefore a very common requirement. It is needed in particular for temporary works, such as excavations below the water table and embankments on waterlogged ground. Dewatering is also needed for some permanent works such as slopes and dams. This chapter gives a review of the subject and further information can be found in Bell (1987), BS 5930 (1981), Cripps et al. (1986), Hanrahan et al. (1989), ICE (1982, 1987, 1989), Patrick Powers (1981), Somerville (1986) and Weltman and Head (1983).
