In Lagos, where water scarcity and unreliable municipal supplies are common challenges, boreholes have become a lifeline for many residential, commercial, and industrial properties. At Naki Services Limited, with over nine years of experience drilling and maintaining boreholes across the state, we understand the importance of a reliable water source. This guide provides essential tips on borehole drilling, installation, and ongoing maintenance to help you avoid common pitfalls and ensure long-term efficiency.

Why Boreholes Are Essential in Lagos

Lagos’s growing population and urban development have strained traditional water sources, making boreholes a popular alternative. A well-drilled borehole can provide consistent access to groundwater, reducing dependency on erratic public supplies or expensive tanker deliveries. However, success depends on proper site selection, drilling techniques, and maintenance. Poorly executed projects can lead to low yield, contamination, or structural failures, costing thousands in repairs.

Key factors influencing borehole viability in Lagos include soil composition (often sandy or clay-heavy), depth requirements (typically 60-300 meters), and proximity to contaminants like septic systems or industrial areas. Professional assessment is crucial to determine feasibility and optimal depth.

Step-by-Step Guide to Borehole Drilling

1. Site Survey and Planning

Before drilling begins, conduct a geophysical survey using resistivity methods to identify aquifers. This step helps estimate water yield and depth, avoiding dry holes. In Lagos, coastal areas may require deeper drilling due to saline intrusion, while inland spots like Ikorodu offer better shallow options.

  • Tip: Engage certified experts like our team at Naki Services to handle permits from the Lagos State Water Regulatory Commission, ensuring compliance with environmental standards.

2. Drilling Process

Using rotary or percussion drilling rigs, create a hole lined with PVC or steel casings to prevent collapse. Depths vary: residential boreholes often reach 100-150 meters, while industrial ones may go deeper for higher volume.

  • Benefits: Modern equipment minimizes noise and disruption, completing most projects in 2-5 days.
  • Considerations: Monitor for artesian pressure to avoid overflows, and test water quality immediately after drilling.

3. Pump Installation and Commissioning

Install submersible pumps suited to your needs—solar-powered for eco-friendly options or electric for high-demand setups. Commissioning includes flow testing and electrical integration.

  • Tip: Opt for energy-efficient pumps to reduce operational costs, especially in areas with frequent power outages.

Maintenance Best Practices

Regular maintenance extends your borehole’s lifespan from 10-20 years and prevents issues like silt buildup or pump failure.

Routine Checks

  • Monthly: Inspect pumps for unusual noises or reduced flow; clean screens to remove sediments.
  • Quarterly: Test water for pH, bacteria, and minerals; rehabilitate if yield drops below 50%.
  • Annually: Professional servicing, including casing integrity checks and geophysical re-assessment.

Common Issues and Solutions

  • Low Water Yield: Caused by aquifer depletion or blockages—solve with hydro-fracturing or deeper redrilling.
  • Contamination: Prevent with proper sealing and regular disinfection using UV or chlorine treatments.
  • Pump Failures: Address through timely replacements and surge protection against power fluctuations.

Pro Tip: Sign up for maintenance contracts to ensure 24/7 emergency response, minimizing downtime.

Cost Factors and Long-Term Savings

Drilling costs in Lagos range from ₦500,000 for shallow residential boreholes to ₦5,000,000+ for deep commercial ones, including pumps and tanks. Maintenance packages start at ₦50,000 annually. The ROI is evident: a well-maintained borehole can save up to ₦200,000 yearly on water purchases while increasing property value.

Conclusion

A properly drilled and maintained borehole is a smart investment for sustainable water access in Lagos. By following these tips, you can enjoy reliable, clean water for years. At Naki Services Limited, our certified professionals handle everything from initial surveys to ongoing support, ensuring excellence every step of the way.
