The cost depends heavily on depth, geology, location, permits and equipment. For example, drilling alone is often quoted at around KES 6,000–9,000 per metre in many Kenyan counties.

When you include hydrogeological surveys, casing, pump installation and storage/distribution, typical total costs for a residential borehole may reach KSh 1 million+ (about KES 1m to 3m or more) depending on complexity.

It’s essential to get a detailed quote and understand what’s included (e.g., casing, pump, tank, quality testing).
