The use of sumps and ditches inside an excavation is one of the basis systems of dewatering found in construction. The water that goes into these installed units can be drained.
The general method of dewatering with sumps and ditches is demonstrated below.
The sump is situated under the ground level of the excavation at one or various corners or the sides. The method consists of the cutting of a small ditch close to the bottom of the excavation, that is dropping towards the sump.
The sump is titled for the shallow pits which are excavated along the boundary of the excavation or the drainage area. It is called as ditches. Due to the action of gravity, the water will pour to the sumps from the slopes. The sumps preserve the water and drenched later on.
Adequate amount of seepage can lead to raveling or sloughing or softening of the slope in the lower part. The slump bottom may depend on piping.
To get rid of the issue mentioned above, inverted filter, that contains various filters, should be utilized. It contains coarser material in successive layers from the bottom of the sump pit to the ascendant direction.
This easy-to-follow method is applied for dewatering shallow excavations containing coarse grained soils or the soils which have permeability in excess of 10-3 cm/sec.
