Ground Dewatering: Wellpoint & Basement Solutions
United Rentals provides wellpoint, deep well and basement dewatering solutions to lower groundwater and keep excavation, foundation and lift pit works safe, stable and on schedule. Whether you're excavating a shallow trench or managing groundwater on a multi-level basement, our engineered systems are matched to your site's soil conditions and depth requirements. Extracted groundwater may need treatment before discharge - see our water treatment solutions for testing, clarification, filtration and dosing.
Our fleet includes submersible pumps to extract groundwater from wellpoint and deep well systems, powered by diesel or electric generators on sites without mains power, supported by our in-house temporary works engineering team for lift pit and basement construction.
- Wellpoint dewatering for shallow to medium-depth excavations
- Deep well dewatering for larger or deeper groundwater control
- Basement and foundation dewatering for lift pits and substructure works
- Submersible pumps to extract groundwater, powered by diesel or electric generators
- Temporary works design (TWD) support for lift pits and basement construction
- Remote telemetry monitoring of water levels and pump performance
- Water treatment solutions to help meet discharge requirements
Groundwater is one of the most common causes of delay on excavation and foundation projects. Our teams assess site conditions and design a dewatering system that lowers groundwater to a safe working level, keeping your excavation stable and your project moving.
Services
Wellpoint & Deep Well Dewatering
Our wellpoint systems lower groundwater in shallow to medium-depth excavations, while deep well systems support larger or deeper groundwater control needs, in both diesel and electric configurations.
Basement & Foundation Dewatering (Lift Pits)
We support basement, foundation and lift pit dewatering on tight or complex sites, including multi-level substructure works where groundwater control is critical to safety and schedule.
Temporary Works Engineering & Design
Our in-house engineering team designs dewatering systems for lift pits and basement construction, including layout, pump sizing and staging to suit your site's soil and groundwater conditions.
Submersible Pumps & Power Supply
Our submersible pumps extract groundwater from wellpoint and deep well systems, powered by diesel or electric generators selected to suit noise, power access and site conditions.
Remote Monitoring
Telemetry monitoring of water levels and pump performance gives your team real-time visibility without requiring constant site presence.
Water Treatment
Groundwater from wellpoint and deep well systems may need treatment before discharge. Our water treatment solutions cover testing, clarification, filtration and dosing to help meet your discharge requirements.
Industries We Support
- Residential and commercial basement construction
- Civil infrastructure and utility trenching
- Mining and quarry excavation
- Road, rail and tunnel substructure works
- Environmental remediation and groundwater control
Frequently Asked Questions
It depends on soil permeability, excavation depth and how far you need to lower the water table. Our team assesses these factors on site rather than recommending a standard package.
Wellpoint systems generally suit shallower excavations in sandy or permeable soils, while deep well dewatering suits larger or deeper groundwater control needs. We'll assess your soil report and excavation plan to recommend the right fit.
Cost depends on the system type, hire duration, depth and pump configuration required. Contact us with your site details for a tailored quote.
Yes, our submersible pumps are powered by diesel or electric generators, so you can choose the configuration that suits your site's power access and noise requirements.
Yes, our teams regularly design and install dewatering systems for basement and lift pit works on constrained or multi-level sites.
Yes, our in-house engineering team designs dewatering layouts, pump sizing and staging for lift pit, basement and excavation projects.
Yes, our telemetry systems track water levels and pump performance remotely, reducing the need for constant on-site monitoring.
In most cases, extracted groundwater needs treatment before discharge. Discharging to stormwater or sewer without treatment can breach your discharge licence or trade waste agreement. Our water treatment solutions test your site's water quality and recommend clarification, filtration or dosing to meet your discharge requirements.
