Drilling
Comprehensive guide to borehole water testing and purification: reverse osmosis, defluoridation, iron filtration, water softeners, and KEBS potable standards.
Design and construction of elevated steel water towers, pressed-steel panel tanks, gravity reticulation networks, and automated float systems across Kenya.
How to restore low-yielding or defunct boreholes in Kenya: downhole CCTV camera inspection, high-pressure air flushing, chemical descaling, and pump servicing.
Pump Testing
How air-source heat pumps powered by solar PV slash water heating electricity bills by up to 75% for Kenyan hotels, hospitals, boarding schools, and homes.
High-resolution field photography capturing Milimani water infrastructure projects across Kenya—from heavy rig mobilization and hydrogeological drilling, through test pumping and solar installation, to final community commissioning and transformative WASH access.
Deploying Milimani's custom-built Down-The-Hole (DTH) pneumatic rig and logistics support trucks to remote ASAL field locations, complete with compressor units and drilling tooling.
Pastoralist elders, mothers, and youth gather around the drill site as operations kick off. Community participation builds long-term local governance, security, and ownership.
The technical service rig conducts borehole pump testing and pump installation onsite. Pastoralist community members and elders gather with water containers as aquifer yield and pumping equipment are verified.
Submersible pump drop pipes, heavy-duty power cabling, and motor assembly staged neatly alongside storage tanks, ready for precision lowering into the borehole column via the field hoist truck.
Following yield assessment, our engineering crew in safety PPE uses the vehicle hoist rig to connect and lower the multi-stage stainless steel submersible pump and riser column to depth.
Step-drawdown and continuous 24-hour test pumping measuring aquifer recovery rate, sustainable cubic-meter output per hour, and initial water physical clarity.
Casting a reinforced concrete sanitary apron, lockable valve vault, and surface chamber around the borehole collar to permanently protect the aquifer from surface run-off contamination.
High-clearance galvanized steel frame engineered above livestock reach, mounting Tier-1 monocrystalline solar panels with weatherproof smart MPPT inverter/controllers for zero-fuel pumping.
System commissioning delivers immediate pressurized drinking water directly from the solar-driven pump into waiting collection containers with zero diesel noise or ongoing fuel cost.
Women and adolescent girls collect water safely in minutes at their doorstep, eliminating treacherous 5-10 km daily treks and enabling girls to attend school regularly.
Sanitary concrete troughs separated from human drinking areas provide safe, high-capacity watering for pastoral cattle, sheep, goats, and donkeys during severe dry spells.
The completed ecosystem: reliable solar groundwater simultaneously meeting domestic WASH needs, school hydration, kitchen gardens, and herds for multi-decade resilience.
