Water Engineering: Drilling, Rehabilitation & Development Solutions

  • Drilling and development of boreholes
  • Rehabilitation and repairs of boreholes

 

At OAJ & Company Investment Limited, we provide integrated water infrastructure services designed to construct, restore, and maximize clean water access for corporate, commercial, and industrial operations. By combining geophysical expertise, advanced heavy machinery, and precise hydrogeological testing, we deliver reliable and high-yielding borehole systems built to stand the test of time.

Our end-to-end water engineering solutions span three critical stages: Precision Drilling, System Repair & Rehabilitation, and Flow Yield Development.

Our Core Water Services

1. Professional Borehole Drilling

We execute turn-key well construction using high-capacity rotary drilling rigs tailored to varied geological formations.

  • Geophysical Site Survey: Advanced ground-resistivity testing and hydrogeological analysis to identify optimal aquifer depths before drilling begins.

  • Deep Borehole Boring: Heavy-duty mechanical drilling through diverse soil, clay, and hard-rock formations.

  • Casing & Screen Installation: Precision installation of heavy-duty PVC or steel casings and engineered well screens to lock out sediment and maintain structural integrity.

2. Borehole Repairs & System Rehabilitation

Restoring aging, clogged, or low-performing water wells back to peak operational capacity.

  • High-Pressure Flushing: Utilizing air compressors and high-pressure water jets to blast out sand, mud, and organic sediment blockages.

  • Safe Chemical Rehabilitation: Applying eco-friendly, food-grade chemical treatments to dissolve mineral scaling, rust deposits, and bio-fouling.

  • Submersible Pump Overhaul: Diagnostic evaluation, repair, or replacement of damaged submersible pumps, control panels, and mechanical components.

3. Well Development & Flow Optimization

Maximizing water output, increasing aquifer recharge rates, and ensuring long-term water safety.

  • Surging & Air-Lifting: Reversing water flow dynamics to clear micro-particulates from the surrounding formation and maximize filter sleeve permeability.

  • Yield Boosting & Capacity Enhancement: Enhancing fluid flow channels to ensure sustained, high-volume discharge under continuous industrial demand.

  • Water Quality & Flow Testing: Comprehensive pumping tests paired with laboratory water quality analysis to guarantee physical, chemical, and microbiological safety.

Why Work with OAJ?

  • Turnkey Execution: From ground survey to final laboratory water certification, we manage every phase under a single contract.

  • Industrial Grade Equipment: Modern rotary rigs, heavy-lift cranes, and precision hydro-testing gear capable of handling deep commercial installations.

  • Long-Term Asset Protection: Our preventive maintenance and rehabilitation techniques double the operational lifespan of commercial wells while reducing pump failures.
