Dewatering is an essential process in construction, infrastructure, mining, and water management projects where groundwater or accumulated water must be removed to maintain safe and dry working conditions. Depending on the project requirements, dewatering systems can be classified as either temporary or permanent.
Understanding the differences between temporary and permanent dewatering systems helps engineers, contractors, and project owners select the most effective solution for their specific application. Each system serves a different purpose and is designed to operate for varying durations.

What Is a Dewatering System?
A dewatering system is a combination of pumps, pipelines, wells, drainage structures, and control equipment used to remove groundwater or surface water from a specific area.
The primary objectives are to:
  • Lower groundwater levels
  • Maintain dry working conditions
  • Improve soil stability
  • Protect structures and equipment
  • Prevent flooding
The choice between temporary and permanent dewatering depends on the long-term water management needs of the site.

What Is a Temporary Dewatering System?
A temporary dewatering system is installed for a limited period during construction or excavation activities. Once the project phase is completed, the dewatering equipment is removed.

Image description
Dewatering pumps are widely used in construction sites, excavation projects, mining operations, tunneling works, and infrastructure developments to remove groundwater and accumulated water. However, groundwater is not always clean. In many cases, especially in the UAE, water contains suspended particles such as sand, silt, and fine sediments that can significantly affect pump performance and lifespan.
Understanding how sand and silt impact dewatering pumps is essential for selecting the right equipment, reducing maintenance costs, and ensuring reliable operation throughout a project.

What Are Sand and Silt?
Sand and silt are naturally occurring soil particles commonly found in groundwater and excavation sites.
Sand
Sand particles are relatively coarse and abrasive. They can vary in size from fine grains to larger particles that are easily carried by flowing water.
Silt
Silt consists of much finer particles than sand. These particles remain suspended in water for longer periods and can pass through many filtration systems.
Both materials are commonly encountered during:
  • Basement excavations
  • Foundation works
  • Utility trenching
  • Mining operations
  • Quarry dewatering
  • Coastal construction projects

Increased Abrasive Wear
One of the most significant effects of sand and silt is abrasive wear on pump components.
As particles pass through the pump at high velocity, they act like sandpaper on internal surfaces.

Components Most Affected:
  • Impellers
  • Wear plates
  • Diffusers
  • Pump casings
  • Mechanical seals
Over time, this abrasion reduces component thickness and affects pump efficiency.

Impeller Erosion
The impeller is responsible for generating flow and pressure within the pump.
Continuous exposure to sand-laden water can cause:
  • Surface erosion
  • Reduced vane thickness
  • Loss of hydraulic efficiency
  • Increased vibration
As the impeller wears, the pump must work harder to deliver the same flow rate.

Reduced Pump Efficiency
Sand and silt gradually increase internal clearances between moving and stationary components.
This can result in:
  • Internal recirculation
  • Reduced discharge pressure
  • Lower flow rates
  • Increased energy consumption
Even moderate wear can noticeably reduce pump performance over time.

Mechanical Seal Damage
Mechanical seals protect the motor from water intrusion.
Sand particles can become trapped between seal faces and cause:
  • Scratching
  • Seal leakage
  • Increased friction
  • Premature seal failure
Seal failure is one of the most common maintenance issues in dewatering pumps operating in sandy conditions.

Bearing Wear
Fine abrasive particles may eventually affect bearing systems.
Potential problems include:
  • Increased friction
  • Excessive vibration
  • Bearing overheating
  • Reduced bearing life
Proper sealing and regular maintenance are important for protecting bearings from contamination.

Increased Risk of Clogging
Although dewatering pumps are designed to handle some solids, excessive sediment can cause blockages.
Common clogging points include:
  • Pump inlets
  • Suction strainers
  • Impeller passages
  • Discharge pipelines
Clogging reduces flow and may lead to pump shutdowns.

Reduced Cooling Efficiency
Many submersible pumps rely on surrounding water for motor cooling.
Heavy sediment accumulation around the pump can:
  • Restrict water circulation
  • Reduce heat dissipation
  • Increase motor temperatures
Elevated operating temperatures can shorten motor life and reduce reliability.

Frequent Maintenance Requirements
Pumps operating in sandy groundwater typically require more frequent inspections and maintenance.
Common maintenance tasks include:
  • Impeller inspection
  • Seal replacement
  • Wear plate replacement
  • Strainer cleaning
  • Bearing inspection
Ignoring maintenance can lead to unexpected failures and costly downtime.

Higher Energy Consumption
As wear increases and efficiency decreases, pumps consume more energy to achieve the same performance.
This results in:
  • Higher operating costs
  • Increased power demand
  • Reduced overall system efficiency
For long-term dewatering projects, energy losses can become significant.

Shortened Pump Lifespan
Continuous exposure to abrasive particles accelerates wear throughout the pump.
Consequences include:
  • More frequent repairs
  • Increased spare parts consumption
  • Reduced service life
  • Earlier equipment replacement
Selecting the correct pump for abrasive conditions can significantly extend equipment life.

Common Sources of Sand and Silt in UAE Projects
Construction projects in the UAE often encounter sandy groundwater due to local geological conditions.
Common sources include:
  • Desert soils
  • Coastal developments
  • Excavation below groundwater level
  • Reclaimed land projects
  • Infrastructure construction
These conditions make abrasion resistance an important consideration when selecting dewatering equipment.

How Modern Dewatering Pumps Handle Sand and Silt
Manufacturers design specialized dewatering pumps for abrasive applications.

Wear-Resistant Impellers
Constructed from:
  • High-chrome alloys
  • Hardened cast iron
  • Stainless steel
These materials resist abrasion better than standard components.

Heavy-Duty Mechanical Seals
Specialized seal materials provide improved resistance to abrasive particles.

Hardened Wear Plates
Replaceable wear plates protect major pump components from excessive damage.

Open or Semi-Open Impeller Designs
These designs allow better passage of sediment and reduce clogging risks.

Best Practices for Pumping Sandy Water
Select the Right Pump
Choose a pump specifically designed for abrasive conditions.

Avoid Oversizing
Oversized pumps can create excessive velocities that increase wear.

Monitor Pump Performance
Regularly check:
  • Flow rate
  • Pressure

  • Strainers
Regular maintenance prevents major failures.

Position Pumps Properly
Avoid placing pumps directly on the bottom of excavation pits where sediment concentration is highest.
Using pump stands can reduce sediment intake.

Consider Sediment Control Measures
Methods may include:
  • Settlement pits
  • Sedimentation tanks
  • Filter systems
  • Geotextile barriers
Reducing sediment levels helps protect pumping equipment.

Signs of Sand-Related Pump Wear
Common indicators include:
  • Reduced flow rate
  • Lower discharge pressure
  • Increased energy consumption
  • Excessive vibration
  • Seal leakage
  • Frequent clogging
  • Unusual operating noise
Early detection helps minimize repair costs and downtime.

  • Increased Power Usage: As the pump works harder to move more water, its energy consumption rises. Submersible pumps may become less energy-efficient during heavy rainfall due to higher load conditions, which translates to higher operational costs.
  • Efficiency Drop with Time: When pumps work harder than usual for prolonged periods, their efficiency can decrease over time. A pump that isn’t regularly maintained or that has become worn down from excessive rainfall may require more energy to achieve the same level of performance, increasing electricity bills.

9. Potential for Overflows and Flooding
  • Risk of Pump Failure: In extreme rainfall, the water volume may exceed the pump's capacity, especially if it is undersized or not operating at peak efficiency. This can result in flooding or overflow, which may damage infrastructure or require additional intervention.
  • Delayed Drainage: Pumps that are not functioning optimally may take longer to remove water, delaying the drainage process and increasing the risk of water accumulation in low-lying areas.

10. Mitigating the Impact of Heavy Rain on Submersible Pumps
  • Regular Maintenance: To minimize the impact of heavy rainfall on submersible pump efficiency, regular inspections and maintenance are critical. This includes cleaning filters, checking for debris, inspecting seals, and ensuring the electrical components are dry and secure.
  • Proper Sizing and Backup Systems: Ensuring the pump is appropriately sized for the expected rainfall volume is key. Additionally, using backup pumps or power systems can help ensure continuous operation during extreme conditions.

Heavy rainfall can put significant strain on submersible pumps, impacting their efficiency and longevity. While they are built to withstand wet conditions, the increased water volume, debris, power supply issues, and continuous operation required during intense rain can lead to reduced performance.
