As water utilities and industrial operators respond to evolving treatment requirements, climate resilience pressures, and growing interest in water re-use, modular and retro fit friendly technologies are increasingly important.

R&D consultancy Sagentia Innovation says modern upgrade strategies have major implications for companies supplying equipment, monitoring systems, and treatment solutions to the water sector.

Suppliers need to demonstrate how products can integrate with existing systems while supporting operational continuity and resilience. For technologies used in water filtration, pumping, sensing, monitoring and treatment, interoperability and ease of deployment are becoming as important as core performance.

Michele Turitto PhD, Managing Partner, Industrial at Sagentia Innovation, says companies supplying the water sector need to balance multiple demands:

“Industrial water operators are placing greater emphasis on how easily technologies can be deployed, integrated, scaled, and maintained. They face significant challenges, but full system replacement is rarely practical or cost-effective. So, OEMs are under growing pressure to deliver high-performance technologies that also support phased, flexible upgrade strategies. The ability to operate effectively across complex environments involving multiple stakeholders is key.”

Aging infrastructures can make it difficult to respond to evolving requirements around treatment, PFAS removal, and water re-use. Consequently, modernisation projects are becoming more site-specific and operationally complex.

According to Sagentia Innovation, seamlessly retrofitting smart solutions without triggering significant engineering overhead in the short term presents challenges for OEM’s, however, systems that feature IoT connectivity, predictive maintenance analytics and optimised chemical dosing, should ensure strong positioning for the future to extract maximum value from R&D and innovation investments.

Technology opportunities in the water sector:

How can water technology OEMs design solutions for retrofit and modular upgrades?

Water technology OEMs should prioritise modular architectures, plug-and-play components, and backward compatibility to enable seamless integration with legacy systems. Solutions that minimise downtime and engineering complexity are more attractive to utilities pursuing phased upgrades.

What capabilities do OEMs need to compete in modern water infrastructure projects?

OEMs need to deliver solutions that combine high performance with interoperability, scalability, and ease of deployment. Increasingly, buyers expect technologies that support retrofit strategies, multi-vendor integration, and long-term operational resilience.

Why is interoperability critical for OEMs supplying the water sector?

Interoperability ensures equipment, sensors, and treatment technologies can connect and function within existing infrastructure and digital ecosystems. For OEMs, this reduces adoption barriers and makes solutions more viable in complex, multi-stakeholder environments.

How are IoT and predictive maintenance shaping OEM product development?

OEMs are embedding IoT connectivity, real-time monitoring, and predictive analytics into their offerings to help operators reduce downtime, optimise performance, and lower lifecycle costs. These capabilities are becoming key differentiators in procurement decisions.

What market drivers are influencing OEM priorities in water technology?

Key drivers include aging infrastructure, stricter treatment requirements (e.g. PFAS removal), climate resilience, and water reuse demand. These pressures are pushing OEMs to develop solutions that are flexible, retrofit-friendly, and adaptable to site-specific challenges.
