About us

Water Reimagined. Resilience Engineered.

About us

Kos-PureAqua engineers custom, decentralised water purification and wastewater treatment systems. We provide fully integrated, automated solutions that allow individuals, industries, communities, and organisations to reclaim, reuse, and responsibly manage water.

Our modular, self-cleaning units are monitored in real time to ensure consistent performance. They significantly reduce freshwater demand, lower both operational costs and CO₂ emissions, and can integrate with solar power for near net-zero operation.

Engineered for diverse applications, from homes and hotels to agriculture, industries and urban infrastructure, our mission is to deliver water security, sustainability, and dignity to every client we serve.

What We Do

At Kos-PureAqua we provide end-to-end support, from initial consulting through design, engineering, and construction to delivery, installation, and ongoing maintenance support. Each solution is custom developed based on client specifications, intended application, and raw water quality. Our tailored approach ensures every system is perfectly suited to its environment and purpose.

Our portfolio includes bespoke, decentralised units for treating groundwater, surface water, and municipal supplies, plus systems for wastewater recycling for non-potable uses and in industrial and agricultural settings.

We also supply rapidly deployable mobile units for off-grid communities, emergency relief, and military operations. Across all applications, our goal is constant: to deliver reliable, resilient water systems built for long-term sustainability.

Core Technologies

Our philosophy is that water treatment is not one-size-fits-all. Every source and need is unique.

We apply a suite of proven, certified technologies, including Membrane Bioreactors (MBR), Reverse Osmosis, Ultrafiltration, Nanofiltration, disinfection media, UV, Activated Carbon, and Remineralisation, deliberately and with precision.

Each project begins with a deep understanding of client needs: water quality, flow rates, usage patterns, and operational conditions. We then design and manufacture a system tailored to these realities. The result is high performance, reliable infrastructure characterised by minimal maintenance, low operational costs, and long-term resilience.

In water treatment, there are no shortcuts, only intelligent, considerate design.
