Smart Biosphere - North Devon Real-Time Digital Catchment Monitoring

Smart Biosphere - North Devon Real-Time Digital Catchment Monitoring

Project Name: Smart Biosphere
Area: North Devon UNESCO Biosphere
Organisation: Biosphere Foundation

1. Overview

The Smart Biosphere is a transformative environmental intelligence project based in the North Devon UNESCO Biosphere, the UK’s first designated biosphere reserve. Launched to address growing public concern and political pressure surrounding river pollution, the initiative integrates real-time monitoring, machine learning, and big data to manage water quality at the catchment scale.

Led by the Biosphere Foundation, and supported by a wide range of partners including the Environment Agency, Siemens, CGI, IGI, Amazon, Ordnance Survey, Rothamsted Research, and Southwest Water, the Smart Biosphere delivers a scalable, affordable framework for intelligent catchment management.

At the heart of the system is a robust sensor network-designed, deployed, and maintained by environmental technology company WATR. Their innovative sensor infrastructure captures high-resolution, real-time water quality data, even in the face of complex environmental challenges. WATR’s strategic planning and deployment across diverse terrain has made real-time data possible in locations previously unmonitored, from remote upland headwaters to agricultural floodplains.

2. Objectives

The project was designed to:

• Detect, predict, and prevent pollution events through real-time monitoring and AI modelling.
• Improve water quality at vulnerable sites, notably Combe Martin beach, which has struggled with bacterial contamination and bathing water quality failures.
• Deliver a scalable Environmental Intelligence Platform (EIP) that integrates water, weather, soil, and land-use data for better decision-making.
  Enable timely interventions by landowners, regulators, and water utilities to reduce pollution from agriculture and wastewater.
• Set a new standard for catchment-scale monitoring that is low-cost, modular, and replicable across the UK.

3. Description

The Smart Biosphere combines Internet of Things (IoT) technology, Earth observation, and artificial intelligence into a seamless decision-support system.

Phase 1: Deployment & Integration by WATR

The initial phase of the project focused on identifying and mitigating pollution in the stream flowing into Combe Martin beach-one of the key risk areas in the biosphere. This phase involved the deployment of 52 sensors, including:

• 52 WATR units including: Bankside and Floating Platform
• Advanced capabilities such as Tryptophan/CDOM sensing and real-time E. coli monitoring, achieving performance benchmarks comparable to top level industry standards.

WATR was instrumental in planning and executing deployment across challenging topographies. Their systems are solar-powered, self-contained, and remotely accessible, making them ideal for areas with limited infrastructure.

A key innovation was the integration of AI and machine learning models with the real-time E. coli data, significantly improving pollution prediction accuracy. This allowed the team to identify sources and patterns of contamination, and even advise local stakeholders-such as farms-on when to adjust activities (e.g., fertiliser application) to avoid runoff events.

All WATR unit readings were fully integrated into the Siemens Mindsphere platform, enabling advanced analytics, secure data management, and intuitive dashboards for stakeholders.

Phase 2: Expansion into Rain and Soil Monitoring

Phase 2 expanded the system to understand not just the “what” but the “why” of pollution:

• 15 Depth Sensors to track hydrological response.
• 16 additional WATR units: including: Bankside and Floating Platform
• 10 WATR Rain units
• 46 WATR Soil units

These additions were essential to evaluate the effectiveness of natural filtration systems like reed beds, buffer zones, and tree planting. By linking soil moisture and rainfall data to water quality readings, the project is now able to assess how well these interventions reduce nutrient and bacterial runoff-bringing new scientific rigour to nature-based solutions.

The combination of water, soil, and rainfall data forms the backbone of an AI-powered model that can anticipate pollution events and trigger pre-emptive actions, such as public health alerts or land management adjustments.

4. Results

The Smart Biosphere has already demonstrated transformative impact:

• Over 130 sensor units deployed, including high-specification WATR devices, covering critical points across two river catchments.
• Real-time E. coli data integrated with AI, achieving over 91% predictive accuracy in lab-tested models.
• Combe Martin beach has shown early signs of water quality improvement, offering hope for sustained Blue Flag status.
• The deployment of soil and rain sensors has advanced understanding of runoff behaviour and enabled targeted ecological interventions.
• WATR’s robust planning and modular system design ensured high data continuity across diverse and challenging terrain.
• Data is fully integrated into Siemens Mindsphere, enabling secure, scalable analytics.
• The project has become a national case study for affordable catchment-scale monitoring, attracting attention from regulators, local authorities, and environmental groups across the UK.
• Expansion plans are underway to cover two more catchments, supporting water companies and councils in meeting net zero and biodiversity goals.

Conclusion

The Smart Biosphere is a bold demonstration of how real-time data, AI, and environmental expertise can combine to protect rivers and communities. At its core is the work of WATR, whose intelligent sensor planning and cutting-edge technology have enabled continuous, high-quality monitoring across a complex and vital landscape.
By bringing environmental monitoring into the digital age, the Smart Biosphere offers a scalable, cost-effective solution to one of the UK’s most pressing challenges-and lights the path for catchments across the nation.

Next steps include expanding the citizen science program and introducing eDNA monitoring to enhance biodiversity tracking and community engagement even further.

Comments

“There is very much a fear in the community of what would happen if the bathing water status was rescinded. It would impact the cafes, the restaurants, the B&B’s… people want to come to a clean place to enjoy themselves.

Here in the UNESCO biosphere reserve, we are keen to push the boundaries of the application of science to improve sustainability of the environment and the links between people and nature. The collaboration with SEEDS is a great opportunity to take our work in digital twinning in a catchment and test its enhancement with remote sensing for water pollutants.”

Andrew Bell, Chief Executive Officer - North Devon Biosphere

“The Smart Biosphere is a powerful example of how real-time data and environmental innovation can protect our rivers and coasts. At WATR, we’re proud to have delivered the sensor infrastructure that made this possible-enabling continuous, high-quality monitoring across one of the UK’s most challenging catchments.

By combining IoT technology with AI and strategic deployment, we’ve helped deliver predictive insights that are already improving water quality at places like Combe Martin beach.

This project shows what’s achievable when technology, science, and collaboration come together. With our partners, we’ve created a scalable, cost-effective model for intelligent catchment monitoring-one that we believe can transform water management across the UK.”
