Engineered Wellpoint Dewatering Systems
Total Dewatering Services provides complete wellpoint dewatering solutions for civil infrastructure, construction, utility and mining projects throughout Perth and regional Western Australia.
Wellpoint dewatering is an effective method of lowering groundwater levels in sandy and permeable ground conditions. A series of closely spaced wellpoints is installed around or alongside the excavation and connected to a common header pipe and pumping system.
This creates controlled groundwater drawdown, helping maintain dry and stable conditions for excavation, trenching, pipework, foundations and other below-ground construction activities.
TDS can manage the complete wellpoint process, from early site assessment and system planning through to installation, commissioning, monitoring, maintenance and removal.

Where Are Wellpoint Systems Used?
Wellpoint dewatering can be used for a wide range of civil and construction applications, including:
Pipeline and utility trenches
Sewer and drainage installation
Pump station construction
Basement excavations
Building foundations
Road and rail infrastructure
Civil earthworks
Culvert installation
Tank and pit excavations
Temporary groundwater control
Wellpoint systems are particularly suited to shallow or staged excavations where groundwater needs to be consistently lowered across a defined work area.
Complete System Design and Installation
A successful dewatering system requires more than placing pumps around an excavation. Ground conditions, groundwater inflow, excavation staging and discharge arrangements all influence how the system should be designed.
TDS brings together technical knowledge and practical site experience to develop a wellpoint system suited to the project.
Our team can coordinate the required equipment, install the wellpoints and header pipe, commission the pumping system and manage it throughout the works. The system can also be adjusted as the excavation progresses or site conditions change.
Environmental and Discharge Management
Water removed during dewatering must be managed responsibly.
Depending on the project, discharge water may require monitoring, treatment, temporary storage or controlled transfer before it can be discharged or reused.
TDS can support the wider water-management process through:
Groundwater monitoring
Flow monitoring
Discharge planning
Temporary water storage
Water-transfer systems
Environmental compliance support
Water-treatment coordination
Project documentation and reporting
Where treatment is required, TDS can integrate suitable solutions through trusted specialist partners.
