5 Common Borehole Issues and How to Fix Them

Boreholes are a reliable source of water for many households and businesses. However, like any mechanical system, they can encounter issues that may disrupt their performance. Here are some common borehole problems and solutions to get your water flowing again:

1. Low Water Yield

Cause: Depletion of the aquifer, clogged filters, or a poorly designed borehole.
Solution:
- Recharge the Aquifer: Implement water conservation measures and avoid excessive pumping.
- Clean the Filters: Hire a professional to clean or replace the filters.
- Redrill the Borehole: In severe cases, consider deepening the borehole or drilling a new one.

2. Water Quality Problems

Cause: Contamination from surface runoff, mineral deposits, or bacterial growth.
Solution:
- Install a Water Treatment System: Use filters, chlorination, or UV disinfection to purify the water.
- Regular Maintenance: Clean the borehole and pump regularly to prevent contamination.
- Conduct Water Testing: Regularly test the water quality to identify and address any issues.

3. Pump Failure

Cause: Mechanical wear and tear, power surges, or incorrect installation.
Solution:
- Regular Maintenance: Schedule regular inspections and servicing of the pump.
- Install a Surge Protector: Protect the pump from power fluctuations.
- Replace Worn Parts: Replace any damaged or worn-out components.

4. Sand Ingress

Cause: Loose borehole casing, worn-out pump components, or excessive pumping.
Solution:
- Repair the Casing: Seal any gaps or cracks in the casing.
- Replace Pump Components: Replace worn-out impellers and other components.
- Reduce Pumping Rate: Lower the pumping rate to reduce stress on the borehole.

5. Noise and Vibration

Cause: Cavitation, misalignment, or worn-out bearings.
Solution:
- Check Pump Alignment: Ensure the pump is properly aligned with the motor.
- Replace Worn Bearings: Replace any damaged bearings.
- Adjust Pump Settings: Adjust the pump's settings to reduce cavitation.

Essential Drilling Facts

Fact 1: Know Your Borehole Casings

The Preferred Borehole Casing In Zimbabwe Is Class 9 and 10 (Pressure Classes.)

This is because Class 9 and Class 10 Casings are more collapse resistant. The strength of a Casing is often described as collapse resistance.

Fact 2: Borehole Drilling Depth

The exact depth, of where the water is located, cannot be established by the drilling contractor nor the Water Surveyor (Borehole Siter).

Fact 3: There Is No 100% Guarantee

It is important to note that it is never a 100% guarantee that any hole will yield water, the amount and water quality can also not be guaranteed by the drilling contractor and water surveyor.

Fact 4: Siting Is Important

Making use of a hydrologist or traditional water diviner will increase your chances of having a successful borehole that will yield a sufficient amount of water.

Fact 5: Know The Risks

The risk of the borehole drilling lies with the property owner. The client will still be liable for the drilling costs irrespective of a borehole yielding water or not.
