About Curio Water

Curio is an independent water treatment engineering company with over 30 years of experience across the full treatment train — from ozone and UV disinfection to filtration, carbon technologies, and emerging contaminant removal.

OUR APPROACH

Our independence allows us to approach every challenge with a goal of finding the most suitable solution – we understand that the pollutants present at each water site may vary, and often require a bespoke, tailored solution.

We assess the entire treatment process, combine the best-fit technologies, and work with trusted partners to deliver engineered solutions that perform in the real world. That might mean designing new systems from the ground up, upcycling aging assets to outperform their original design, or fixing underperforming infrastructure that others have walked away from.

Our clients come to us when they need to do more with what they already have, whether that's meeting tightening regulations on micropollutants, PFAS, and emerging contaminants, reducing operational costs and carbon footprint, or building resilient infrastructure that will perform for the next 20 years.

We support water utilities so they can deliver cleaner water, more efficiently, without unnecessary capital replacement.

A tailored treatment train, not just a single product

Prioritising asset upcycling over replacement

Independent expertise, long-term partnerships

Curio services and maintains equipment across all major manufacturers — not just our own — and we're actively engaged with research institutions like Cranfield University.

This independence and expertise mean our clients get honest advice, long-term thinking, and a single point of accountability across the full treatment process.

We also recognise that no single company can solve global challenges alone, so we work together with engineers, water scientists, and technology specialists to deliver the next generation of scalable solutions.
