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[1]. 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 industrialize 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

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.
