We didn't reinvent the wheel. We applied globally proven water treatment, solar and packaging technologies to the specific constraints of Sierra Leone, then designed a phased three-site rollout to keep every kilometre of distribution short, fresh and resilient.
Deep borehole at each site draws underground mineral water, solar-pumped. Free supply after installation, zero per-litre water cost.
30kW solar array with battery storage drives the submersible pump and the rest of the facility. Zero diesel, zero grid dependency.
Reverse osmosis system with multi-stage sand, carbon and UV treatment. WHO-standard output, consistently tested at every batch.
500ml PET bottling line for mass market plus aluminium canning line for premium and hospitality. Two formats, one quality standard.
Short-haul distribution from each of three sites into local mass market, mid-tier retail, premium hospitality and B2B accounts.
Each site sits on its own borehole. Once drilled, the water source is free, with no per-litre cost, no seasonal variability, and no dependence on surface water quality or rainfall.
A solar-powered submersible pump draws water to the surface treatment facility. The borehole system is the foundation of Bana Water's cost advantage, eliminating the largest variable cost in traditional water production.
A reverse osmosis system sits at the heart of every production facility. Multi-stage filtration removes all contaminants, bacteria and viruses to deliver consistently WHO-standard drinking water.
The system uses sand filtration, activated carbon, and UV treatment before and after the RO membrane. A proven configuration used in water treatment facilities worldwide, adapted for off-grid operation.
A 30kW solar panel array with battery storage provides 100% of each facility's energy needs, from water pumping and treatment to bottling, canning and lighting. Zero diesel. Zero grid. Zero emissions in production.
Battery storage with 4,000+ cycle life ensures production continues through cloudy periods and after dark. Sierra Leone receives an average of 5+ peak sun hours per day, more than sufficient for reliable year-round operation.
Industry-standard PET bottling for the 500ml mass-market line, paired with a professional aluminium canning line for 330ml and 500ml hospitality formats. Two formats, one quality standard.
Plastic recycling partnerships are wired in from day one. Aluminium is infinitely recyclable with 95% energy savings compared to virgin production, and the can collection network grows alongside hospitality channel volumes.
