At Additive Catchments, we are building the civic infrastructure society needs to restore river health. As a mission-led company majority-owned by a non-profit, we provide independent data, transparent insights, and actionable intelligence to rebuild public trust and enable better, collective water governance. Through our Catchment Monitoring as a Service (CMaaS®) platform, we integrate IoT sensors, AI-driven analytics, earth observation, and low-code tools into an open, scalable system - giving industry, government, organisations and the public, the power to act, together.  

Through our work we: 
- Provide Catchment Monitoring as a Service (CMaaS) 
- Run the River Health Perception Index (RHPI) 
- Deliver Continuous Water Quality Monitoring (CWQM) 
- Build open and holistic data infrastructure, integrating insights from our partners across the ecosystem 

We are here to help give rivers a voice, restore public trust, and build a future where rivers, communities, and society thrive.
