Understanding Site Dewatering from Start to Finish

Understanding Site Dewatering from Start to Finish

Introduction

Dewatering is one of the first and most essential steps in preparing a construction site, especially in the UAE where high groundwater levels and sandy soil conditions are common. Whether you are building a foundation, trenching for utilities, or installing infrastructure, proper site dewatering ensures safety, stability, and compliance.

This blog will walk you through the full dewatering process from planning to execution, with insights from the experts at Arabian Equipment [AER].

Step 1:

Site Assessment and Groundwater Study

The first step is understanding the site conditions. A professional groundwater assessment is conducted to determine:

• Water table depth

• Soil permeability

• Expected inflow rate

• Required drawdown level

This information guides the choice of dewatering method and equipment sizing. AER works closely with contractors and consultants during this phase to provide technical input on system design.

Step 2:

Selecting the Dewatering Method

Based on the site study, you will choose a method that best fits the project’s requirements.

Common options include:

• Wellpoint System – ideal for shallow excavations in sandy soil

• Deep Well System – suited for deep excavations with high inflow

• Sump Pumping – simple setup for small-scale or short-term jobs

Arabian Equipment [AER] provides all these systems and can advise on the most efficient setup for your location.

Step 3:

System Design and Permit Preparation

Before installation, detailed drawings and technical documents are prepared. These include:

• Layout plan with pump and well locations

• Method statement and discharge strategy

• Flow rate and filtration details

• Environmental and safety considerations

Most municipalities in the UAE require this documentation to issue a dewatering permit or No Objection Certificate (NOC). AER supports clients by supplying equipment specifications and assisting with compliance requirements.

Step 4:

Equipment Mobilization and Installation

Once permits are secured, AER delivers and installs the selected dewatering system. This includes:

• Pumps and control panels• Suction and discharge piping• Filtration or silt control systems• Backup power or fuel sources as needed

Our field teams ensure the system is safely installed and tested before operation begins.

Step 5:

Dewatering Operations and Monitoring

With the system active, continuous monitoring is essential to ensure:

• Groundwater is maintained at the target level• Discharge quality meets environmental standards• Equipment performance remains stable• Emergency response is ready in case of failure

AER provides site visits, maintenance, and troubleshooting support throughout the duration of the project.

Step 6:

Demobilization and Site Closure

Once excavation or construction below ground is complete, the dewatering system is gradually shut down. Demobilization includes:

• Safe removal of pumps, wells, and pipes• Disinfection or sealing of boreholes• Final flow and soil condition reporting• Clearing discharge points and filtration units

AER handles the full removal process to leave your site clean and ready for the next construction phase.

Conclusion

Understanding the full dewatering process allows contractors to plan better, avoid delays, and meet compliance standards with confidence. From early site surveys to final pump removal, Arabian Equipment [AER] provides end-to-end support tailored to your project needs.
