What Is Borehole Pump Maintenance?

Borehole pump maintenance is the planned inspection, monitoring, servicing and repair of a borehole pumping system to help keep it operating reliably.

The system may include a submersible pump, electric motor, power cable, control panel, delivery pipe, valves, level sensors, storage tanks and pressure-control equipment.

Maintenance does not always require removing the pump. Many checks can be completed by inspecting accessible equipment and recording operating measurements. Removal is considered when the symptoms and test results indicate that an internal fault needs further investigation.

A good maintenance programme combines routine observation with appropriate technical inspections. It also maintains records of the original installation, previous repairs and measured performance.

Why Is Borehole Pump Maintenance Important?

1. Reducing Unexpected Breakdowns

Regular checks can reveal changes in water flow, pressure, electrical readings or control-system behaviour before a major interruption occurs.

Early investigation may help prevent minor problems from developing into more expensive faults.

2. Maintaining Water Delivery

A pump must deliver sufficient water for the property's actual requirements. Monitoring discharge and pressure helps establish whether performance remains within the expected range.

A decline may indicate pump wear, pipe restrictions, leakage, groundwater changes or another problem that needs investigation.

3. Protecting the Electric Motor

Electrical faults, excessive loading and unsuitable operating conditions can contribute to motor damage.

Checking the electrical supply, operating current and protection arrangements helps identify abnormal conditions.

4. Reducing Unnecessary Repair Costs

Replacing a pump without diagnosing the fault may not solve the problem.

Maintenance checks help distinguish between a defective pump, a control-panel fault, a damaged cable, a pipe restriction and a limitation in the available groundwater supply.

5. Improving Operational Planning

Recorded measurements provide a baseline for future comparison. This helps property owners plan inspections and investigate deterioration based on evidence rather than waiting for complete failure.

Components to Check During Borehole Pump Maintenance

Submersible Pump

The pump assembly should be assessed for signs of reduced performance, abnormal operating conditions and suspected internal damage.

Discharge and pressure measurements help establish whether the pump is operating as expected.

Electric Motor

The motor should operate within its specified electrical and thermal limits. Current, voltage and other relevant measurements can help identify abnormal conditions.

The exact testing procedure depends on the motor design and manufacturer's instructions.

Power Cable

Accessible cable sections and connections should be checked for damage, deterioration and signs of overheating.

Electrical testing may be required if a cable fault is suspected.

Control Panel

The control panel should be checked for correct starting, stopping and protection functions.

Depending on the system, this may involve contactors, overload relays, level controls, pressure switches and variable-frequency drives.

Delivery Pipework

Accessible pipes, joints, valves and fittings should be inspected for leakage, restrictions and visible damage.

A leak or blockage may reduce the water reaching the storage tank even when the pump itself remains serviceable.

Water-Level Protection

Where installed, low-water protection should be checked according to the equipment specifications.

Repeated activation may indicate inadequate water availability, an unsuitable pumping rate or a sensor or control fault.

Storage and Pressure Equipment

Storage tanks, pressure vessels and associated controls should be checked where they form part of the installation.

Faults in these components may cause frequent pump cycling or poor pressure even when the borehole pump is functioning correctly.

Borehole Pump Maintenance Procedure

Step 1: Review Previous Performance

Review available records for the pump model, installation date, motor rating, previous faults and earlier measurements.

Comparing current conditions with previous records helps identify changes.

Step 2: Inspect Accessible Equipment

Check the control panel, accessible wiring, pipework and connections for visible damage, leakage, corrosion or overheating.

Any defect should be investigated before the equipment is returned to normal operation.

Step 3: Check Electrical Operation

A qualified technician may measure supply voltage and operating current and verify that the protection arrangements match the motor specifications.

Electrical work should follow appropriate isolation and testing procedures.

Step 4: Measure Water Discharge

Measure the water delivered under defined operating conditions and compare it with previous readings or expected performance.

A change in discharge may require further investigation of the pump, pipework or groundwater source.

Step 5: Assess Pressure

Pressure measurements help establish whether the system supplies water at the required operating pressure.

Flow and pressure should be interpreted together because either measurement alone may give an incomplete picture.

Step 6: Review Water-Level Behaviour

Where appropriate, check the static and pumping water levels.

A significant change in drawdown may indicate a change in groundwater conditions or that the pumping rate requires reassessment.

Step 7: Test Controls and Protection

Check the operation of relevant starting, stopping and protection devices according to the manufacturer's instructions.

Never bypass overload or low-water protection to keep the pump operating.

Step 8: Document Findings

Record the measurements, defects, corrective actions and recommendations.

These records support future maintenance and provide a reference for investigating subsequent changes.

Signs That Your Borehole Pump Needs Maintenance

A maintenance assessment is advisable when the pump produces less water, takes longer to fill storage tanks, develops unusual noise or vibration, trips repeatedly or fails to maintain expected pressure.

Other warning signs include unstable water delivery, abnormal electrical readings and repeated activation of low-water protection.

These symptoms do not automatically prove that the pump is damaged. They may arise from electrical, mechanical, hydraulic or groundwater-related causes.

Borehole Pump Maintenance for Residential Properties

Residential boreholes supply water for bathing, cooking, laundry, cleaning and other household activities.

Maintenance should consider the pump, control panel, delivery pipe, storage tank and any pressure-control equipment.

Monitoring tank-filling time and discharge can help identify changes in performance. If the water supply becomes unreliable, the system should be assessed before the pump is replaced.

Where demand changes, the pumping schedule and storage arrangement may also need review.

Borehole Pump Maintenance for Farms

Farm boreholes may supply irrigation, livestock and other agricultural operations.

Maintenance should consider the required flow rate, operating duration, pipework, irrigation equipment and borehole water levels where appropriate.

A reduction in discharge may be caused by pump wear, a restriction in the distribution system or a change in groundwater availability.

The findings should guide the corrective action rather than relying on pump replacement alone.

Borehole Pump Maintenance for Commercial Buildings

Hotels, schools, hospitals, apartment complexes and industrial premises may rely on boreholes for essential operations.

Maintenance planning should reflect the importance of the water supply, the pump's duty and the consequences of an interruption.

Keeping records of discharge, pressure, electrical measurements and repairs helps operators identify recurring faults and plan inspections.

Critical installations may also require contingency arrangements to reduce the effects of an unexpected breakdown.

Preventing Dry Running

Dry running occurs when a pump operates without sufficient water available for its intended operation. Depending on the pump design, this condition can cause overheating or internal damage.

Low-water protection and appropriate monitoring can help reduce the risk.

If the protection device repeatedly stops the pump, investigate the water level, pumping rate, sensor condition and control settings.

Do not repeatedly reset the system without identifying the cause.

Preventing Electrical Damage

Electrical faults can affect both the motor and the control equipment.

Maintenance should include appropriate checks of the supply, cables, connections and protective devices.

The technician should compare measurements with the motor nameplate and manufacturer's specifications.

Loose connections, damaged insulation and repeated overload trips require prompt investigation. Electrical protection should never be bypassed.

Maintenance and Pump Performance Testing

Maintenance and performance testing complement one another.

Maintenance involves planned checks and servicing, while performance testing uses measurements to assess how the system operates under defined conditions.

Performance measurements can help determine whether maintenance has restored the expected discharge or pressure.

If the measurements remain abnormal, further diagnosis may be required.

When Should a Borehole Pump Be Removed for Inspection?

A pump should not automatically be removed for every problem.

If the fault can be traced to an accessible control panel, supply connection, pipe or valve, the problem may be addressed without lifting the submerged assembly.

Removal may be appropriate when the evidence points to an internal pump or motor fault, damaged submerged cable or another issue that cannot be adequately assessed from the surface.

Removal and reinstallation require suitable lifting equipment and safe handling procedures.

How Often Should Borehole Pump Maintenance Be Done?

There is no single maintenance interval suitable for every borehole installation.

The frequency depends on operating hours, pump type, water quality, operating conditions, maintenance history and the importance of the water supply.

Follow the manufacturer's recommendations and establish an appropriate inspection schedule for the installation.

Additional checks are advisable when performance changes, repeated trips occur or the system has undergone significant repairs.
