Meet the AER Team: A Day in the Life of a Dewatering Technician

Behind every successful construction project is a team of professionals working to keep operations running safely and efficiently. In dewatering, one of the most important roles is that of the dewatering technician, who helps ensure that pumping systems operate reliably and groundwater is managed throughout construction activities.

At Arabian Equipment Rental LLC (AER), dewatering equipment and operational support play an important role in helping contractors address groundwater challenges across construction and infrastructure projects.

But what does a typical day look like for a dewatering technician? From inspecting pumps and monitoring water levels to troubleshooting equipment and coordinating with site teams, the role requires technical knowledge, practical skills, attention to detail, and a strong commitment to safety.

1. Starting the Day: Site Preparation and Safety Checks

A dewatering technician's day often begins with reviewing the work schedule, checking site conditions, and preparing for planned inspections or maintenance activities.

Before starting work, the technician should understand the day's priorities, any reported equipment issues, and the operational requirements of the dewatering system.

Safety is a key priority. Depending on the site and equipment involved, initial preparations may include:

• Inspecting the work area for visible hazards.

• Confirming that access routes around pumps and pipelines are safe.

• Reviewing equipment operating records and previous shift reports.

• Checking that emergency procedures and communication arrangements are understood.

• Identifying outstanding maintenance or operational concerns.

These preparations help ensure that daily activities begin in a controlled and organised manner.

2. Inspecting Dewatering Equipment

Once the initial safety checks are complete, the technician inspects the dewatering equipment to confirm that it is operating as expected.

Depending on the system, this may involve diesel-driven pumps, electric pumps, submersible pumps, wellpoint systems, generators, hoses, manifolds, and discharge pipelines.

Typical inspection activities include:

Pump performance: Checking operating conditions and confirming that the pump is functioning within its specified limits.

Pipelines and connections: Looking for leaks, loose fittings, blockages, and signs of wear that could affect water movement.

Power supply: Inspecting electrical connections or generator operating conditions, where applicable, and checking for reported power interruptions.

Supporting equipment: Confirming that accessories, controls, and other system components are in suitable working condition.

Any significant defect should be reported and addressed according to the applicable safety procedures and maintenance requirements.

Regular inspections help identify developing problems before they lead to unplanned downtime.

3. Monitoring Groundwater Levels

One of the most important responsibilities in dewatering is helping maintain groundwater levels within the requirements established for the project.

Excavation activities can be affected by changing groundwater conditions, particularly in areas with shallow water tables or permeable soils. Rainfall, variations in groundwater inflow, and changes in excavation depth can also influence system performance.

A dewatering technician may record groundwater measurements, review pump operating data, and report changes to the site engineer or responsible supervisor.

Monitoring activities can include:

• Recording groundwater levels at designated monitoring points.

• Checking pump operation and flow measurements where available.

• Observing changes in water accumulation within excavations.

• Reporting unusual increases in groundwater inflow.

• Maintaining accurate inspection and operating records.

These observations help the project team determine whether the system is performing as intended and whether further investigation or adjustment is necessary.

Technicians should follow the project's monitoring plan and obtain the required authorisation before changing critical groundwater targets or system settings.

4. Troubleshooting and Solving Site Problems

Construction sites are dynamic environments, and equipment problems can arise even when systems are properly planned and maintained.

A technician may encounter reduced pumping performance, blocked strainers, leaking hoses, unexpected water inflow, or interruptions to the power supply.

The first step is to identify the issue, assess the associated risks, and inform the responsible supervisor. Where necessary, equipment must be isolated before inspection or repair, following the applicable procedures.

Depending on the problem, corrective work may involve cleaning accessible components, checking connections, arranging equipment servicing, or assisting with an approved change to the pumping arrangement.

For example, if a pump's performance decreases, the technician may help investigate whether the cause is a blocked intake, an air leak, a pipeline restriction, or a mechanical issue.

The objective is to identify the underlying cause rather than simply address the immediate symptom. Effective troubleshooting requires technical understanding, attention to detail, clear communication, and a disciplined approach to safety.

5. Working with the Construction Team

Dewatering technicians do not work in isolation. Their responsibilities are closely connected to the activities of excavation crews, site engineers, plant operators, and other construction personnel.

Communication is essential when excavation progresses into a new area, equipment needs to be relocated, or pipeline routes must be adjusted.

For example, the construction team may require a change in the dewatering layout as work advances. The technician can help identify practical installation considerations and communicate operational risks to the responsible team.

Coordination also helps prevent pipelines from obstructing vehicle movements, lifting operations, or site access routes.

By sharing accurate information and reporting concerns promptly, technicians contribute to better coordination and help the wider team make informed decisions.

6. Preventive Maintenance: Keeping Equipment Reliable

Preventive maintenance is another important part of a dewatering technician's routine.

Pumping equipment may operate for long periods under demanding site conditions. Without appropriate inspections and servicing, normal wear, contamination, or component deterioration can affect reliability.

Depending on the equipment type and manufacturer recommendations, maintenance activities may include:

• Checking filters, strainers, and accessible intake components.

• Inspecting hoses, seals, couplings, and fittings.

• Reviewing operating hours and scheduled service intervals.

• Checking generator fuel and servicing requirements where applicable.

• Recording equipment defects and maintenance actions.

• Reporting components that require repair or replacement.

Maintenance should be performed by appropriately authorised personnel using the correct procedures.

A structured maintenance routine helps reduce avoidable failures, support equipment reliability, and maintain effective pumping operations throughout the project.

7. Maintaining Accurate Records

Documentation is an essential part of professional dewatering operations.

Accurate records help supervisors understand equipment performance, identify recurring problems, and track changes in groundwater conditions over time.

Depending on project requirements, a technician may complete daily inspection checklists, record operating hours, document maintenance activities, and report unusual groundwater measurements or equipment failures.

Clear records also support communication between shifts, helping incoming personnel understand the current operating status and any outstanding issues.

Consistent documentation contributes to accountability and provides useful information for maintenance planning and project management.

8. End-of-Day Checks and Handover

Before finishing the shift, the technician reviews the condition of the equipment and confirms that important operational information has been communicated.

Where continuous pumping is required, the system must remain in its approved operating condition and should not be shut down simply because the technician's shift has ended.

End-of-day responsibilities may include:

• Completing outstanding inspections and maintenance records.

• Reporting defects or unusual operating conditions.

• Confirming that equipment and work areas are left in a safe condition.

• Communicating unresolved issues to the supervisor or incoming shift.

• Highlighting planned maintenance or operational changes.

A thorough handover helps maintain continuity between shifts and reduces the likelihood of important information being missed.

The Skills Behind a Successful Dewatering Technician

Working in dewatering requires a combination of practical experience, technical understanding, and professional responsibility.

Technical knowledge: Understanding pump operation, pipelines, supporting equipment, and basic groundwater control principles.

Problem-solving: Recognising unusual equipment behaviour and helping identify the underlying cause of operational issues.
