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.
A single canning line fills 500ml cans for the mass market and 330ml cans 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 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.
A professional canning line fills, seams and codes 500ml cans for the mass market and 330ml cans for premium and hospitality channels. One line, one material, two formats, one quality standard.
Running a single packaging material simplifies the whole operation: one procurement stream, one changeover, one collection network. Aluminium is infinitely recyclable with 95% energy savings compared to virgin production, and can collection partnerships are wired in from day one.
