Borehole Drilling & Development
Professional hydrogeological surveys, heavy-duty rotary drilling, steel casing, test pumping, and groundwater development engineered for permanent water security across Kenya.
Scientific groundwater exploration and precision drilling.
Securing reliable underground water requires rigorous geological science, accurate aquifer identification, and proper structural casing to prevent borehole collapse and contamination. At Ubunifu Green Solutions, we manage the technical execution of groundwater development from initial site evaluation to final pump commissioning.
Operating across Nairobi, Nakuru, Gilgil, Naivasha, and nationwide, our technical teams combine advanced geophysical resistivity profiling with heavy-duty rotary drilling equipment to unlock high-yield water sources for farms, residential estates, and commercial institutions.
Complete Borehole Engineering Scope
Professional execution across all stages of groundwater development and stabilization.
Hydrogeological Site Surveys

Frequently Asked Questions
Clear answers to common questions about borehole drilling regulations and procedures in Kenya.
Yes. By law under the Water Act, all borehole drilling requires an abstraction permit and authorization from the Water Resources Authority (WRA), preceded by an Environmental Impact Assessment (EIA). Ubunifu Green Solutions guides and assists clients through all required statutory documentation.
Borehole depths vary significantly depending on local hydrogeological conditions, terrain, and regional geology. Depths can range from shallower zones to over 300 meters. A professional hydrogeological survey of your specific plot is necessary to estimate the depth required.
While conducting a scientific hydrogeological survey informs drilling decisions and site selection, groundwater exploration always carries natural geological variables. Our pre-drilling survey reports provide detailed technical data regarding subsurface potential prior to rig mobilization.
From initial hydrogeological survey and statutory permit processing to drilling, test pumping, lab water testing, and final pump installation, project timelines vary based on permit approvals and site requirements.
