A partnership between Hampshire-based Ordnance Survey and IT and business consulting firm CGI is using a newly-created AI model to remotely detect sewage overspill from space.

This model can predict the conditions which most regularly lead to pollution events with high levels of accuracy.

After an initial first phase, the project will provide a proactive approach to environmental management and nature protection in the North Devon UNESCO Biosphere reserve. The biosphere covers 55 square miles and is centred on Braunton Burrows, the largest sand dune system in England.

It is the latest project undertaken as part of CGI’s SEEDS programme, which is aiming to challenge the thinking and practice around sustainability, launched with the United Nations last year. Earlier this year it was announced that OS and CGI would be working together to use detailed satellite imagery to identify organic matter in waterways.

Mattie Yeta, Chief Sustainability Officer for CGI in the UK said, “Following a successful first phase of the project, which led to the creation of an AI and satellite tool that can predict pollution events with up to 91.5% accuracy, we are excited to launch this second phase, which provides an innovative and proactive approach to environmental management and nature protection.”

By bringing together multiple sources of data, including data from sensors, the new solution will identify where and when pollution incidents take place, or where they may occur in the future.

Using available data from the UK Environment Agency combined with data from CGI, Ordnance Survey, North Devon Biosphere and OpenSource satellite data, the project will use AI to map out where these incidents of pollution have taken place over a time period using CGI’s GeoData360 platform.

“The solution will benefit farmers, governments, water companies and other stakeholders by protecting our water from pollution and contamination, which is vital for both our way of life and the life of our waterways and coast lines,” continued Yeta.

“At CGI, we are committed to providing insights our clients can act on, and with our partners through SEEDS, to bringing our insights and experience to projects such as this where we can really make a difference to our environment and the planet.”

Donna Lyndsay, Strategic Market Lead, Environment & Sustainability at OS, said: “With the innovative technical ability that both CGI and OS have in abundance, we believe we may be able to help provide actionable insights for addressing water pollution events.

“We are looking forward to testing the AI models produced in our previous phase to see how they perform in the real world. We want to see if our work can be really used to support the Biosphere needs in identifying interventions to help preserve and restore our valuable habitats. If successful this has the potential to support remote monitoring of UK waterways for signs of pollution using data that is objective, regularly updated, and scalable.”
