Boreholes

Boreholes drilling, rehabilitation, cleaning and services
Access to reliable water supply remains a critical concern for homeowners, businesses, and agricultural operations across Kenya. While municipal water systems serve many urban areas, supply inconsistencies, rationing schedules, and growing demand have driven property owners to seek alternative water sources. Boreholes offer a sustainable, cost-effective solution that provides independence from municipal water supply while ensuring consistent access to clean water.
Borehole Drilling Services
Professional borehole drilling begins with comprehensive site assessment and geological surveys. Before drilling commences, experienced hydrologists evaluate your property to determine the optimal drilling location, estimate water table depth, and assess expected water yield. This preliminary investigation combines geological data, water divining techniques, and analysis of nearby boreholes to maximize the chances of successful water extraction.

Modern drilling equipment and techniques enable efficient penetration through various geological formations. Depending on your location's geology, drilling depths typically range from 30 to 300 meters. The drilling process involves specialized machinery that creates a vertical shaft while simultaneously stabilizing the borehole walls. Professional drillers use appropriate casing pipes to prevent collapse and contamination, ensuring the borehole's structural integrity and water quality.

Once drilling reaches the water-bearing aquifer, development work begins. This involves cleaning the borehole, installing appropriate screens, and conducting pumping tests to determine sustainable yield rates. These tests provide crucial data about how much water the borehole can reliably produce without depleting the aquifer, ensuring long-term viability of your water source.
Borehole Rehabilitation
Even well-constructed boreholes experience declining performance over time. Reduced water output, increased pumping costs, murky water, or unusual sediment indicate that rehabilitation may be necessary. Borehole rehabilitation restores functionality to underperforming or failed boreholes, often at a fraction of new drilling costs.

Rehabilitation begins with thorough assessment using specialized camera equipment that inspects the borehole's interior condition. This inspection reveals problems such as collapsed casing sections, sediment accumulation, biological growth, or mineral deposits restricting water flow. Based on these findings, technicians develop targeted rehabilitation strategies.

Common rehabilitation procedures include high-pressure jetting to remove sediment and mineral deposits, acid treatment to dissolve calcium carbonate and iron deposits, installation of new screens or casing sections, and re-development of the aquifer interface. In cases where the original borehole cannot be salvaged, deepening the existing hole to reach new water-bearing zones may prove more economical than drilling a new borehole.

Proper rehabilitation can restore boreholes to original performance levels or even improve upon them by implementing modern techniques and materials unavailable during initial drilling. Regular maintenance and timely rehabilitation extend borehole lifespan significantly, protecting your water supply investment.
Borehole Cleaning and Maintenance
Regular borehole cleaning prevents many problems that lead to expensive rehabilitation or replacement. Over time, boreholes accumulate sediment, mineral deposits, bacterial growth, and debris that reduce water quality and flow rates. Scheduled cleaning maintains optimal performance and extends equipment life.

Professional borehole cleaning involves several steps. First, the submersible pump is removed for inspection and servicing. Then, specialized cleaning equipment descends into the borehole to mechanically remove accumulated sediment and deposits. High-pressure water jetting dislodges stubborn materials while chemical treatments address bacterial contamination and mineral buildup.

After cleaning, water quality testing ensures the borehole produces safe, potable water. Tests check for bacterial contamination, mineral content, pH levels, and other parameters affecting water safety and usability. Any issues discovered during testing can be addressed before the pump is reinstalled and regular water use resumes.
Comprehensive Borehole Services
Beyond drilling, rehabilitation, and cleaning, complete borehole services encompass pump installation and repair, electrical work for pump systems, water quality testing and treatment, pressure tank installation, piping and distribution systems, and regular maintenance programs. Professional service providers offer integrated solutions that ensure your entire water system functions reliably.

Pump selection requires matching pump capacity to borehole yield and water demand. Submersible pumps must be correctly sized and positioned to provide adequate pressure while avoiding damage from running dry or excessive cycling. Professional installation includes electrical wiring, control panels, pressure switches, and safety systems that protect equipment and ensure reliable operation.
