Mechanical Cleaning and Restoration

Mechanical cleaning represents a crucial component of Borehole Rehabilitation Service in Nairobi and Kenya, addressing the accumulation of sediments, mineral deposits, and biological growth that commonly reduce borehole efficiency over time.

The cleaning process utilizes specialized equipment including surge blocks, bailers, and high-pressure jetting systems to remove accumulated materials from the borehole and surrounding formation. Mechanical brushing techniques help restore the original diameter of the well casing while removing stubborn deposits that restrict water flow.

For severely compromised boreholes, air-lifting procedures create powerful upward flow that dislodges sediments and debris from the formation face. This process often reveals additional water-bearing zones that had become blocked, potentially increasing the overall yield beyond original capacity.

“Mechanical cleaning can improve borehole yield by 30-70% in cases where siltation and mineral buildup have significantly reduced water production capacity.”

Chemical Treatment and Disinfection

Chemical treatment forms an integral part of comprehensive Borehole Rehabilitation Service in Nairobi and Kenya, addressing contamination issues and mineral buildup that cannot be resolved through mechanical means alone.

Disinfection procedures eliminate harmful bacteria, viruses, and other microorganisms that may have colonized the borehole system. Chlorination remains the most common disinfection method, involving controlled introduction of chlorine compounds followed by thorough flushing to ensure complete pathogen elimination.

Acid treatment addresses mineral scale buildup, particularly calcium carbonate deposits that commonly form in boreholes penetrating limestone aquifers. Specialized acids dissolve these deposits while protecting metal components from corrosion damage.

Biocide applications target biofilm formation and iron bacteria that can severely restrict water flow and compromise water quality. These treatments require careful application to ensure effectiveness while maintaining environmental safety standards.

Pump System Rehabilitation

Pump system rehabilitation represents a critical aspect of Borehole Rehabilitation Service in Nairobi and Kenya, as submersible pumps are often the first components to fail in aging borehole systems.

The rehabilitation process begins with pump extraction and comprehensive inspection to identify worn components, electrical faults, and mechanical damage. Motor windings are tested for insulation breakdown while impellers and diffusers are examined for wear and corrosion damage.

Pump refurbishment includes replacement of worn seals, bearings, and electrical components along with motor rewinding when necessary. Control systems undergo complete overhaul including starter replacement, electrical panel upgrades, and protection system installation.

Proper pump sizing ensures optimal efficiency and longevity, with careful consideration of borehole yield, required flow rates, and total dynamic head. Installation procedures follow industry best practices including proper cable management, torque specifications, and commissioning tests.

“Professional pump rehabilitation can extend equipment life by 8-12 years while improving energy efficiency by up to 25% compared to deteriorated systems.”
