A properly maintained borehole system can provide a dependable water supply while helping protect your home's water quality.Introduction
A borehole can be one of the most valuable water sources in a home, particularly in areas where public water supply is unreliable. But drilling a borehole and installing a pump is only the beginning. The entire system — from the borehole head and submersible pump to the pipes, storage tank and taps — needs regular attention.
Poor maintenance can lead to reduced water pressure, dirty or cloudy water, unusual smells, pump failure, blocked pipes, overflowing tanks and expensive repairs. More importantly, a borehole should not automatically be assumed to provide drinking-quality water simply because the water looks clear.
In this guide, you'll learn practical borehole maintenance tips that can help you keep your water system working efficiently and identify problems before they become expensive. We'll cover routine inspections, pump maintenance, water-quality testing, storage tanks, rainy-season protection, common warning signs and situations where professional help is necessary.
This guide provides general home-maintenance information. Do not enter a borehole, attempt to remove a submersible pump yourself, work on electrical connections with power connected, or make changes to the borehole casing or well structure without appropriate professional assistance. If water quality is questionable, have the water tested before using it for drinking or food preparation.

Why Borehole Maintenance Matters
A borehole system is more than a hole drilled into the ground. It is a combination of underground water infrastructure, a pump, electrical equipment, pipes, valves, a storage system and household plumbing.
When one part begins to fail, the symptoms can appear somewhere else. For example, low water pressure may be caused by a clogged filter, a partially blocked pipe, a failing pump or a problem with the water level in the borehole.
Regular maintenance helps you identify these problems while they are still manageable.
- Protects your water supply: Routine inspections can help identify contamination risks early.
- Extends pump life: Pumps work more efficiently when the system is properly maintained.
- Reduces unexpected breakdowns: Small problems are usually easier and cheaper to correct than major failures.
- Protects your storage tank: Sediment and biofilm can accumulate when tanks are neglected.
- Improves system efficiency: Blocked filters, leaking pipes and faulty valves can make the system work harder.
- Supports better water quality: Regular testing and cleaning help you understand what is actually in your water.
Remember: Not Every Water Problem Is a Borehole Problem
Before assuming your borehole is failing, check whether the problem might actually be in your household plumbing or water system. Some common issues that are not borehole problems include:
- Blocked household filters: Sediment filters and carbon filters can become clogged and reduce pressure.
- Faulty pressure pumps: The booster pump that distributes water around your home may be the culprit.
- Closed or partially closed valves: A valve that was accidentally turned off can restrict flow.
- Internal plumbing leaks: Hidden leaks can reduce pressure at your taps.
- Tank float valve problems: A stuck or faulty float valve can prevent the tank from filling properly.
- Air locks in pipes: Trapped air can reduce water flow and cause sputtering taps.
Always check these simpler possibilities before assuming your borehole pump needs replacement.

Know the Main Parts of Your Borehole System
Before maintaining your borehole, learn the basic components of the system installed at your home. Your exact setup may differ, but most residential systems contain several of the following parts.
1. Borehole Casing
The casing supports the borehole and helps prevent surrounding soil and debris from entering the drilled hole. It should remain intact and protected from physical damage.
2. Borehole Head
The borehole head is the point where the underground borehole meets the surface. It should be protected from flooding, standing water, rubbish, chemicals and other contamination sources.
3. Submersible Pump
The submersible pump is installed below ground and pushes water through the delivery pipe. Because it is located inside the borehole, pump removal and major repairs are normally jobs for a qualified borehole technician.
4. Delivery Pipes
These carry water from the borehole toward the storage tank or pressure system. Leaks, damaged joints and blockages can reduce the amount of water reaching the house.
5. Control Box or Electrical Protection
Depending on the installation, the pump may have a control box, starter, protection device, pressure controls or other electrical equipment. These components should be kept dry and protected from tampering.
6. Water Storage Tank
Many homes pump borehole water into an overhead or ground-level storage tank before distributing it around the property.
7. Filters and Treatment Equipment
Some systems use sediment filters, carbon filters, iron-removal systems, softeners, UV treatment or other equipment. These components require maintenance according to the manufacturer's instructions.
Warning Signs Your Borehole Needs Attention
Do not wait for the pump to stop completely before investigating a problem. Changes in your water system can provide useful early warnings.
- Water pressure suddenly drops: Could indicate a blockage, leak, pump problem or pressure-system issue.
- Water becomes cloudy: May indicate sediment or another water-quality issue that needs investigation.
- Water develops an unusual smell: Have the water tested rather than assuming the smell is harmless.
- Water changes colour: Brown, yellow or reddish water may indicate sediment, iron or other dissolved substances.
- Pump runs much longer than usual: This may indicate increased demand, leakage, a failing pump or another system problem.
- Pump repeatedly starts and stops: Frequent cycling can indicate a pressure-control, tank or plumbing problem.
- Unusual electrical sounds: Buzzing, burning smells or repeated tripping require prompt professional attention.
- Tank overflows: A faulty float valve or level-control system may be responsible.
- Water contains visible particles: Investigate the source instead of simply continuing to use the water.
Monthly Borehole Maintenance Checks
You do not need to dismantle the borehole every month. Most routine maintenance involves inspection and observation.
Check the Borehole Area
- Keep the area around the borehole clean.
- Remove rubbish, standing water and vegetation that could interfere with inspection.
- Look for cracks or visible damage around the borehole head.
- Check that drainage prevents rainwater from collecting around the borehole.
- Keep fuel, pesticides, fertilizers and other chemicals away from the borehole area.
Check Pipes and Connections
- Look for leaking joints.
- Inspect exposed pipes for cracks or physical damage.
- Check valves for signs of leakage.
- Listen for unusual water-flow sounds when the system operates.
Observe the Pump's Behaviour
You don't need to open the pump to monitor it. Simply pay attention to how it behaves.
- Does it take longer than normal to fill the tank?
- Does it switch on and off unusually often?
- Does it make a new or unusual sound?
- Does the pump run continuously without reaching the expected water level?

How to Maintain Your Borehole Pump
The pump is one of the most important and expensive components of the system. Fortunately, homeowners can perform several observations without physically removing or opening the pump.
Don't Run the Pump Without Water
A pump designed to operate underwater should not be allowed to run without an adequate water supply. Dry running can cause serious damage to some pump systems.
If your system frequently runs low on water, ask a qualified technician to investigate the borehole yield, pump setting and protection system.
Watch for Frequent Cycling
If the pump repeatedly starts and stops within short intervals, do not simply ignore it. The cause may be related to pressure controls, a pressure tank, a leak, a faulty sensor or another component.
Protect the Electrical System
Keep electrical control equipment protected from rain, flooding and unnecessary moisture. Do not attempt electrical repairs unless you are appropriately qualified.
Don't Pull the Pump Out Yourself
Removing a submersible pump can involve electrical cables, lifting equipment, pipes and a significant amount of weight. Improper removal can damage the pump, cable or borehole installation.
If the pump needs to be removed, inspected or replaced, use a qualified borehole technician.
Borehole Water Quality: Clear Does Not Always Mean Safe
One of the most important lessons for every borehole owner is this: water that looks clear is not necessarily safe to drink.
Some contaminants cannot be detected by sight, smell or taste. The only reliable way to understand the quality of your borehole water is to have it tested by an appropriate water-testing laboratory.
When Should You Test Borehole Water?
- When a new borehole has just been completed.
- Before using borehole water as drinking water.
- After major repairs to the borehole or plumbing system.
- When the taste, smell or appearance changes.
- After flooding or suspected contamination.
- When household members develop concerns about the water.
- Periodically according to local water-quality guidance or professional advice.
What Can Water Testing Check?
Depending on the laboratory and the intended use of the water, testing may include physical, chemical and microbiological parameters.
Possible parameters include pH, turbidity, hardness, iron, manganese, nitrate, other dissolved substances and microbiological indicators. The correct testing panel depends on your location and how the water will be used.
If a test identifies a problem, do not randomly add chemicals to the water. Use the test results to determine what treatment is actually required.

Clean and Maintain Your Water Storage Tank
Maintaining the borehole while ignoring the storage tank defeats part of the purpose of a clean water system. Water can become contaminated or develop unpleasant odours inside a poorly maintained tank.
Inspect the Tank Regularly
- Check the tank lid or cover.
- Make sure the cover closes properly.
- Check for cracks or leaks.
- Look for signs of insects, dirt or other contamination.
- Inspect the overflow pipe and outlet.
- Check that the tank is securely supported.
Clean the Tank When Necessary
Sediment can accumulate at the bottom of a storage tank over time. The appropriate cleaning interval depends on the tank, water source, sediment load and local conditions.
Before cleaning, isolate the water supply and follow the tank manufacturer's instructions. If disinfection is required, use an appropriate water-system procedure rather than guessing the chemical concentration.
Never enter a water tank. Confined spaces can present serious risks, including drowning, falls and poor air quality.
Keep the Tank Covered
A properly fitted cover helps prevent dust, insects, leaves and other contaminants from entering the tank.
Maintain Pipes, Filters and Water Pressure
Good borehole maintenance does not stop at the pump. Water still has to travel through pipes, filters, valves and household plumbing before it reaches your taps.
Check for Hidden Leaks
A leak can make the pump operate more frequently and waste water. Check visible pipework and investigate unexplained wet areas, damp soil or unusually high water usage.
Maintain Filters
If your borehole system has a sediment filter or other treatment equipment, follow the manufacturer's recommended cleaning or replacement schedule.
A neglected filter can become clogged and reduce water pressure. On the other hand, replacing a filter too early may waste money. Keep a simple record of when cartridges were installed and replaced.
Don't Ignore Low Pressure
Low water pressure may have many causes. Before replacing the pump, check for simple possibilities such as blocked filters, closed valves, leaking pipes or plumbing restrictions.
Protect Your Borehole During the Rainy Season
Heavy rainfall can increase the risk of surface water entering poorly protected areas around a borehole. Good drainage and a properly protected borehole head are therefore particularly important during the rainy season.
Before Heavy Rains
- Inspect the area around the borehole.
- Clear nearby drainage channels.
- Make sure rainwater flows away from the borehole head.
- Check the borehole cover and surrounding structure.
- Inspect the storage tank cover.
- Check exposed electrical equipment for weather protection.
After Flooding
If floodwater reaches the borehole head, do not automatically assume the water remains safe for household use. Flooding can introduce contaminants into water systems.
Stop using the water for drinking and food preparation until the situation has been assessed and appropriate testing or disinfection has been completed.
Common Borehole Problems and What They May Mean
| Problem | Possible Causes | What to Do |
|---|---|---|
| Low water pressure | Blocked filter, leak, pump issue or plumbing restriction | Inspect accessible components and call a technician if unresolved |
| Cloudy water | Sediment, disturbance or water-quality issue | Investigate and test the water |
| Yellow or reddish water | Iron, sediment or other dissolved substances | Test water before selecting treatment |
| Pump runs continuously | Low water level, leak, control problem or pump issue | Switch off if unsafe and have the system inspected |
| Frequent pump cycling | Pressure-control or storage-system problem | Have the pressure system checked |
| Tank overflowing | Faulty float valve or level-control system | Inspect accessible valve and repair or replace if necessary |
| Unusual water smell | Water-quality or plumbing issue | Stop drinking the water and arrange testing |

Common Borehole Maintenance Mistakes to Avoid
1. Assuming Clear Water Is Safe to Drink
Appearance alone cannot confirm drinking-water safety. Test the water if it will be used for drinking or cooking.
2. Waiting Until the Pump Fails
Unusual noise, reduced flow and repeated cycling can be early warning signs. Investigate changes before the system stops working completely.
3. Ignoring the Storage Tank
A clean borehole does not guarantee a clean storage system. The tank, lid, pipes and treatment equipment also matter.
4. Using Chemicals Without Testing
Do not randomly add chlorine, acids or other chemicals because water looks or smells unusual. First identify the problem and use the correct treatment method.
5. Allowing Floodwater to Collect Around the Borehole
Poor drainage around the borehole head can increase contamination risk. Keep surface water moving away from the installation.
6. Attempting Major Pump Repairs Without the Right Equipment
A submersible pump is not a normal household appliance. Removing it can require specialized equipment and knowledge.
7. Forgetting to Keep Maintenance Records
Record pump repairs, water tests, filter changes, tank cleaning and other important maintenance activities. These records make it easier to identify changes over time.
Pro Tips for a More Reliable Borehole System
• Know your normal: Pay attention to normal pump runtime, water pressure and tank-filling time so unusual changes are easier to detect.
• Keep a maintenance log: Write down water-test dates, filter changes, pump repairs and tank cleaning.
• Protect the borehole head: Keep it away from flooding, rubbish, chemicals and other contamination sources.
• Test before treating: Don't spend money on unnecessary filtration equipment until you understand the water-quality problem.
• Maintain the entire system: The borehole, pump, pipes, filters, tank and household plumbing all work together.
• Act on changes early: A small change in pressure, colour, smell or pump behaviour deserves investigation.

Frequently Asked Questions
Routine homeowner inspections can be performed regularly, while professional servicing should depend on the condition and design of the borehole system, pump, water quality and manufacturer's recommendations. Don't wait for a complete failure before arranging an inspection.
Not automatically. Borehole water should be tested before being considered suitable for drinking or food preparation. Clear-looking water can still contain contaminants that cannot be seen, smelled or tasted.
Possible causes include sediment, iron or changes in the water source or plumbing system. The correct response depends on the cause, so water testing is preferable to guessing.
Possible causes include increased water demand, leaks, reduced pump performance, changes in water level or a problem with the control system. A sudden change should be investigated.
The appropriate interval depends on the tank, water source and amount of sediment entering the system. Inspect the tank regularly and clean it when sediment or contamination is found, following appropriate cleaning and disinfection procedures.
It is generally not a suitable DIY task. Removing a pump can require specialized lifting equipment and knowledge of the pump, cable and pipe installation. Use a qualified technician.
Treat the water as potentially contaminated. Avoid using it for drinking or food preparation until the borehole system and water quality have been properly assessed.
