Bringing together Evove, Cerafiltec, and Vortech Water Solutions — three companies at very different stages of their journey through the WATA curve — the Townhall opened a rare, in-the-weeds discussion about market pull, friction, design choices, and the subtle but significant signals that adoption is accelerating. And with perspectives from The Dynamics of Water Innovation authors Paul O’Callaghan, Prof. Cees Buisman (Wetsus) and Dr. Reinhard Hübner (Skion Water), the conversation revealed how today’s realities are reshaping the very framework used to understand innovation in water.

“If the customer is under pressure, things happen.” — Prof. Cees Buisman

One insight became clear quickly: customers are under increasing pressure, and pressure changes timelines. As Cees noted,  Whether driven by regulation, shortages, operational failures, or escalating costs, utilities and industry operators are moving quicker than historical patterns would suggest.

This shift came through strongly in the stories of each company:

• • Evove accelerated from pilot to demo in about four years — nearly half the typical WATA timeline. Chris Wyres attributed this to a conscious “design-for-adoption” mindset, supported by strategic partners who gave customers confidence in deliverability.

  • Cerafiltec reached a point where nearly half of its installed base was wastewater, something that happened because customers kept pushing the company into new applications. As Julius Gloeckner put it, “We repeatedly said no — until we caved.”

  • Vortech saw a turning point when utilities began specifying the technology in tenders. For Sean Mulligan, this was the moment that signalled a shift “from supplier push to market pull,” and with it, a rapid expansion in deployments.

These were not stories of hype or disruption; they were stories of fit, trust, durability, and customer pressure converging to accelerate adoption.

“Innovation doesn’t accelerate because the technology is new, it accelerates when the ecosystem is ready.”— Dr. Reinhard Hübner

The Townhall was also an opportunity to reflect on how these trajectories align with the WATA Model, the framework underpinning The Dynamics of Water Innovation.

The consensus among the authors: the fundamentals haven’t changed, but the conditions around them have. Market friction points remain: procurement cycles, regulatory delays, operational conservatism. Yet macro forces are compressing decision windows in specific sectors.

Reinhard Hübner emphasised the crucial role of ecosystem enablers. Investors, universities, and strategic partners often make the difference between a promising technology and one that moves. 

Designing for the system you have, not the system you want

If there was a recurring theme across all three companies, it was the importance of designing technology that integrates seamlessly into existing systems. Evove’s “Porsche engine in a VW Beetle” analogy captured the essence: adoption accelerates when integration is frictionless.

Cerafiltec’s durability narrative, including installations running 12+ years without performance loss, reinforced the idea that trust is built over time, and durability becomes an accelerant. 

Vortech’s disciplined “build fast, test early, learn relentlessly” mindset showed how transparency and real-world data cultivate credibility.

Across all three stories, the message was consistent: technologies that scale fastest are the ones that lower adoption risk, shorten decision-making, and respect the operating realities of utilities and industry.

The sector is not suddenly fast, but it is faster than it was.

The WATA timelines remain grounded in decades of evidence, but they are bending under new pressures. And the companies that recognise this, and design accordingly, are the ones defining the next chapter.

For innovators, three lessons stood out:

1. 1. Reference data is currency.

   2. Partners change your velocity.

   3. Durability builds trust. Integration removes friction.

The journeys of Evove, Cerafiltec and Vortech show that the path from lighthouse to tipping point is not uniform — but it is patterned, predictable, and increasingly responsive to the moment we’re in.
