Commercial Borehole Drilling
Farms, Mining & Exploration
Industrial groundwater solutions across all 10 provinces of Zambia. From commercial boreholes for large-scale irrigation and mine dewatering to exploratory soil & core sample collection drilling, water tanks, steel tank stands, and solar pump installations.
Commercial & Mining Drilling
Engineered for high daily yields and geoscientific accuracy throughout Zambia's diverse geological terrains.
Commercial Farm Boreholes
High-capacity, large-diameter boreholes delivering thousands of liters per hour for center pivot irrigation, livestock watering, commercial greenhouses, and agricultural processing facilities across Mkushi, Chisamba, Southern, and Central provinces.
- Large casing diameters (8" to 12")
- Deep aquifer penetration for all-season volume
Mining Boreholes & Dewatering
Industrial borehole drilling for mining operations in Copperbelt, Solwezi, and Kalumbila. Specialized in open pit perimeter dewatering, plant process water supply, camp drinking water systems, and environmental compliance monitoring wells.
- Pit dewatering & perimeter drawdown wells
- Heavy DTH rotary rock drilling rigs
Mining Soil & Core Sampling
Exploratory borehole drilling dedicated to soil sample collections and geotechnical lithological core analysis. Assisting mining geologists, civil engineers, and exploration teams with precise sub-surface sampling and stratigraphy logs.
- Mineral exploration sample collection
- Geotechnical soil & strata analysis drilling
The 4 Stages to Guaranteed Water
We follow strict engineering and environmental hydrogeology protocols to guarantee water purity, borehole longevity, and maximum yield.
Hydrogeological Survey & Siting
Scientific geophysical resistivity survey pinpoints underground fractures and high-yield aquifer zones for farm irrigation, mining, or domestic use, avoiding dry holes.
High-Pressure Rotary DTH Drilling
High-pressure pneumatic down-the-hole percussion hammer drills through tough dolomite, quartzite, and schists while sampling geological strata for mining core records.
Class-9 Casing & Silica Gravel Pack
Installation of certified high-collapse Class-9 uPVC casing and precision slotted screens, packed with washed silica gravel to filter sediment and ensure crystal-clear water.
Pump Testing & Storage Commissioning
Continuous 4 to 8-hour step-drawdown test pumping certifies yield (m³/hr). We install turnkey solar or electric submersible pump sets, elevated steel tank stands, and storage tanks.
Why Professional Geophysical Siting & Casing Matter
Zambian ground conditions vary from karstified dolomites and limestone caves in Lusaka to hard granites, quartzites, and copper-bearing stratas on the Copperbelt and North-Western provinces. Without rigorous geophysical resistivity sounding, there is a serious risk of striking dry fractures or contaminated shallow ground seepage.
Captain Investments Limited uses high-spec Class 9 uPVC full casing columns, pressure-grouted surface sanitary seals, and precision gravel packing to deliver clean, silt-free, and high-yielding water that stands the test of decades.
Elevated Tank Stands, Storage Tanks & Solar Pump Sets
Eliminate dependence on load-shedding with our complete off-grid solar groundwater systems. We engineer and erect heavy-duty structural steel elevated tank stands (3m, 6m, 9m, 12m+), install high-capacity water storage tanks (5,000L, 10,000L, 15,000L, 20,000L+), and commission both solar-powered DC submersible pump sets and high-pressure electric AC pump sets with automated float control switches.
