Common Dewatering Challenges and How to Solve Them

Dewatering is essential for safe and efficient construction, but it does not always go according to plan. Especially in the UAE, where ground conditions vary from coast to desert, contractors often face a range of site-specific challenges that can delay progress and increase costs.

At Arabian Equipment (AER), we help clients overcome these challenges with expert systems, local knowledge, and proven solutions. Below are the most common dewatering problems we see on UAE job sites and how to solve them.

1. High Water Table and Rapid Inflow

The challenge

Many areas in the UAE, especially along the coast, have shallow water tables. Once excavation begins, groundwater can rush in faster than expected and overwhelm basic pumping systems.

The solution

Use wellpoint systems for shallow water control or deep well systems for higher volume needs. AER assesses groundwater levels and provides customized solutions to ensure pumps are properly sized and installed for local conditions.

2. Fine Sand and Soil Instability

The challenge

Loose sand or silty soils, common across UAE projects, can clog pumps, collapse trench walls, or lead to unstable excavation zones.

The solution

Install proper filters and well screens to prevent clogging. AER also recommends gradual drawdown methods to stabilize soil layers and avoid settlement or collapse during excavation.

3. Power Supply Limitations on Remote Sites

The challenge

In desert or infrastructure projects far from urban centers, stable electricity may not be available, which causes delays and poor equipment performance.

The solution

AER provides diesel powered, trailer mounted pumps with backup options. These ensure reliable operation even in off grid locations such as oil fields, pipelines, or rural developments.

4. Delays in Permit Approval or Discharge Compliance

The challenge

All groundwater discharge must comply with UAE environmental and municipality regulations. Failure to secure permits or meet disposal standards can result in penalties or forced shutdowns.

The solution

AER supports contractors with documentation and system designs that meet UAE authority requirements. Our team helps with fast-track approvals and ensures full compliance with discharge policies and environmental controls.

5. Equipment Downtime and Maintenance Issues

The challenge

Harsh weather, continuous operation, and poor maintenance can cause pump failures and site flooding, which slows down project progress.

The solution

AER offers routine site inspections, scheduled maintenance, and quick equipment replacements. Our pumps are designed for heavy duty performance in UAE environments and come with onsite support.

6. Limited Access or Confined Excavation Areas

The challenge

In urban areas like Dubai or central Abu Dhabi, excavation often happens in tight locations where standard dewatering setups cannot fit.

The solution

AER provides compact submersible pumps and flexible pipe systems that work in restricted areas while still delivering strong performance.

Conclusion

Every construction site in the UAE brings its own set of dewatering challenges. Whether you are working on a villa foundation in Sharjah or a major infrastructure site in Abu Dhabi, having the right dewatering setup is crucial. Arabian Equipment provides the knowledge, tools, and on ground support to keep your site dry, stable, and on schedule.
