The drilling depth varies depending on your location and geological conditions:

• Coast: from about 30 metres
• Nairobi and surrounding areas: most new boreholes are between 150 and 300 metres because the upper aquifer is over extracted
• Arid Northern Kenya: often over 300 metres
• Hydrogeological surveys: we survey every site to determine the optimal depth before drilling

Our experienced team uses geophysical survey equipment to locate the best water source and the most efficient drilling depth for your specific location. Read more on the average water table in Kenya.

Actual drilling rarely takes more than 5 days. Typical drilling timeframes:

• Residential boreholes: 1 to 3 days depending on depth and soil conditions
• Commercial projects: 3 to 7 days for larger capacity requirements
• Community projects: 5 to 10 days including testing and setup
• Site conditions: rocky terrain may require additional time

From the first survey to commissioning, expect 4 to 10 weeks in total, as permits take the longest. We provide realistic timelines during our initial consultation and keep you updated throughout.

After successful drilling, we provide complete installation services:

• Water testing: quality analysis to ensure safe, clean water
• Pump installation: the right pumping system for your needs
• Tank construction: water storage solutions as required
• Distribution setup: plumbing connections to your property
• System testing: complete functionality checks before handover
• Training: basic maintenance and operation guidance

We don’t just drill and leave. We make sure you have a complete, functioning water system that meets your long term needs.

Borehole drilling costs vary based on several factors:

• Depth required: cost per metre varies by geological conditions
• Diameter size: larger boreholes cost more but provide higher yields
• Location accessibility: remote areas may have additional transport costs
• Additional services: pumping systems, tanks, and testing add to total cost
• Rock formations: harder geology requires specialised equipment

We provide site visits and detailed quotations with transparent pricing, with no hidden charges. For an instant estimate, try our borehole cost calculator.

Dry boreholes are rare when a proper hydrogeological survey is done first, which is why we never drill without one. Our approach to reducing risk:

• Pre drilling surveys: thorough geophysical assessment of your site
• Experience: 16+ years of drilling across Kenyan geology guides site selection
• Local knowledge: deep understanding of Kenyan aquifers and water patterns

No drilling company can guarantee water 100% of the time. If a borehole does come out dry, you are not charged the full cost. You pay only part of it, and the exact terms are written into your drilling agreement before any work starts.
