FAQs

A complete drilling project typically takes 3–7 days, depending on geology, depth, and site access. The workflow includes a hydrogeological survey, mobilization, drilling, casing, test pumping, and final equipping.

Yes. A survey identifies underground water zones, estimates depth, and predicts yield. It significantly reduces the risk of drilling a dry or low‑yield borehole. We coordinate surveys through licensed professionals.

You will need approvals from:
• Water Resources Authority (WRA)
• NEMA (where environmental assessment is required)
• County Government
• Additional clearance letters where applicable

Milimani Drilling supports clients through the entire permit process.

Costs vary by location and geology. Drilling rates generally fall between KES 6,000–10,000 per meter. A fully equipped borehole — including drilling, casing, pump installation, tower, and permits — may range from KES 500,000 to several million, depending on system design.

Depth depends on geological conditions. Most boreholes in Kenya range between 50m and 250m. The hydrogeological report determines the recommended depth.

Absolutely. A properly drilled borehole can supply water for irrigation, livestock, crop spraying, greenhouses, and general farm operations. It is a long‑term investment for agribusiness.

Yield variations can occur, but several improvement methods exist, including:
• Borehole development
• Airlifting
• Adjusting screens and casing
• Re‑evaluation of the aquifer
We advise on the best yield optimization approach for your site.

Borehole water can be safe for drinking, but water quality testing is essential. Testing identifies whether treatment such as filtration, chlorination, or mineral balancing is needed before domestic use.

Pump selection depends on depth, yield, and available power.
Options include:
• Electric submersible pumps
• Solar‑powered pumps for off‑grid or cost‑efficient operation

We provide full pump sizing and installation guidance.

Routine maintenance includes:
• Annual water testing
• Pump inspection
• Electrical system checks
• Occasional cleaning or rehabilitation

Regular servicing ensures long‑term reliability.

A well‑constructed and properly maintained borehole can remain functional for 20–50 years or more.

Yes. We design and install steel towers, elevated stands, plastic or steel tanks, and pressure management systems tailored to your water needs.

Yes. Solar pumping systems are ideal for farms, institutions, and rural homes. They reduce operational costs and provide dependable water supply even in off‑grid areas.

Yes. We perform 24‑hour pump tests to determine borehole yield, recovery rate, and sustainable pumping capacity.
