Arihant dewatering Systems believes the key to successful dewatering is reliable and personalized service. Great care is taken to satisfy the contractor's specific needs, develop the proper system for the specific site conditions and maintaining a reliable operation until the project is complete.

Open dewatering systems enable one to lower the groundwater table adequately in cohesive and low permeable soils. Water is pumped off directly from sumps (ditches) along the toes of the slopes of the excavation works. The suction hose with strainer is merely placed in the sump and the collected water is primed and discharged. This makes the open dewatering system easy to install and simple to operate. The open dewatering system utilizes selfpriming or vacuum assisted centrifugal pumps

As shown in well point system consists of a number of wellpoints spaced along a trench or around an excavation site, all connected to a common header which is attached to one or more wellpoint pupms. Wellpoint assemblies-made up of a wellpoint, screen, riser pipe, and swing joint with tuning-are genrally installed by jetting. They provide for entry of water into the system by creation of a partial vacuum. The water is then pumped off through the header pipe. A wellpoint pump is a combination of two pumps, one of which pumps water from the header and the other of which is a vacuum pump to remove air which enters the system. Control of air is important, as excessive air causes cavitation which reduces pump efficiency.

Dewatering pumps are designed specifically for the dewatering function. They are available in capacities from 50-200 ltrs per second. Wellpoint systems are frequently the logical and economic choice for dewatering construction sites where the required lowering of ground water level is on the order of 15 feet or less. Greater lifts are possible by lowering the water in two or more stages. The 15-foot lift restriction results from the fact that the water islifted by difference between ambient air pressure and the lowered pressure created by the pump.
