• It is occupied by alluvium consisting of sand clay and gravel. Ground water occurs both inder water table and confined conditions in the granular beds in the alluvial deposits. It is developed by means of shallow filterpoints wells within a depth of nine metres. The soil is greyish black and is essentially clayey in composition. A few thin layers of sandy clay or  sand, not exceeding 0.3 metre in thickness are intercalated with the clayedsoil.
