Additive Catchments and Capgemini partner to lead AI-driven transformation of UK river health

London, February 11, 2025 – Additive Catchments and Capgemini today announce a key partnership in the UK to scale Additive Catchments’ Catchment Monitoring as a Service (CMaaS®) platform. The collaboration addresses the critical need for continuous water quality monitoring mandated by the UK’s 2021 Environment Act, as currently only 14% of England’s rivers meet good ecological health standards. Together, the two companies aim to deliver high-assurance data and insights, helping water companies and stakeholders to comply with regulations, tackle pollution, and drive meaningful environmental improvements.

As part of the agreement, Capgemini will provide services to Additive Catchments to industrialise its CMaaS^® platform, which combines advanced sensor networks, AI-driven insights, and digital capabilities.

Capgemini will drive the platform’s scalability and innovation, leveraging its deep expertise in AI, data, and digital transformation. It will provide the following services to Additive Catchments:

• Ongoing R&D capability, to drive advancements in machine learning, earth observation and smart maintenance
• Digital capabilities, such as virtual sensors, to reduce costs and environmental impact
• Business consulting services including strategic ESG advisory and carbon monitoring consulting
• Operational and software platform management to ensure long-term scalability and impact

“This collaboration reflects Capgemini’s commitment to working with high-potential ventures that drive sustainability and digital transformation. By combining Additive Catchments’ innovative platform with our expertise, we aim to help water companies take control of this critical challenge and deliver on their regulatory and environmental responsibilities,” said Rob Walker. Managing Director of the UK Business Unit, Capgemini. “2025 is a pivotal year for the UK’s water industry, and we are proud to contribute to a solution that addresses this national priority.”

“This relationship marks a defining moment for Additive Catchments. With Capgemini’s support, we are well positioned to accelerate the delivery of our solution and scale its impact across the UK, enabling water companies and stakeholders to meet critical regulatory challenges while driving tangible improvements in river health. Together, we are forging a new path for innovation and collaboration in environmental stewardship,” said Rob Passmore, CEO & Co-founder, Additive Catchments.

Addressing the river health crisis

The 2021 Environment Act requires all water companies in the UK to implement continuous monitoring upstream and downstream of discharge points, creating the world’s largest environmental monitoring program. With over £100bn expected to be invested during AMP8, the upcoming 5-year regulatory cycle that starts in April 2025 to improve infrastructure and environmental outcomes, this initiative represents an unprecedented opportunity to improve river health.

The CMaaS^® platform supports this transformation by delivering actionable insights to water companies, enabling targeted interventions and proactive responses to pollution. By addressing a key regulatory challenge, the collaboration also creates a scalable solution for global environmental monitoring needs.

Empowering a multi-stakeholder ecosystem

The CMaaS^® platform integrates data from diverse sources, such as sensors, satellite imagery, the Met Office, Environment Agency and other public datasets. It delivers actionable insights to a broad range of stakeholders, including water companies, landowners, farmers, and local communities. By facilitating targeted interventions, the platform drives measurable improvements in river health while enhancing collaboration for sustainable water management.
