Surface dewatering system 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 self priming and vacuum assisted centrifugal pumps.
General applications and benefits: Surface Dewatering System
1. Excavation and Foundation Works
Primary Use: Removing surface water from open excavations, foundations, or trenches.
Purpose: Keeps the work area dry to allow safe excavation, concrete placement, and structural works.
Example: During basement or footing construction in high water table areas, surface pumps prevent flooding.
2. Road and Highway Projects
Application: Dewatering of low-lying stretches or borrow pits during roadbed preparation and compaction.
Purpose: Ensures uniform soil compaction and prevents surface runoff from damaging under-construction pavements.
3. Mining and Quarrying Operations
Application: Temporary removal of accumulated rainwater or seepage from open pits or working benches.
Purpose: Prevents operational downtime and allows continuous excavation and hauling activities.
4. Infrastructure and Utility Projects
Application: Draining water from construction of metro lines, drainage systems, culverts, underpasses, and tunnels.
Purpose: Maintains dry conditions for concrete and mechanical works, and protects equipment from submersion.
5. Stormwater and Monsoon Management
Application: Emergency or seasonal dewatering of flooded construction sites, storage yards, and access roads.
Purpose: Quick restoration of site accessibility after heavy rainfall or monsoon events.
6. Groundwater Level Control (Temporary)
Application: Works alongside wellpoint or deep well systems where combined control of surface and subsurface water is required.
Purpose: Prevents surface inflow that can re-flood areas already treated by subsurface dewatering.
Typical Equipment Used
Centrifugal cum vacuum dewatering pumps (diesel or electric driven) like ADS LHF, MHF & BHF series pumps
Vacuum-assisted dewatering pumps for rapid priming
Flexible suction/discharge hoses, strainers, and pipelines
