StormHarvester and Anglian Water began working together in 2022 as part of Anglian Water’s Dynamic Sewer Visualisation (DSV) programme.
The Anglian Water Dynamic Sewer Visualisation (DSV) programme was launched in February 2023. Their proactive sewer monitoring programme was designed to identify restrictions in the network before they turned into an escape and cause negative impact on their customer and the environment.
THE CHALLENGE
Sewer blockages are a major cause of pollution and flooding incidents, often only detected once damage has occurred. Anglian Water needed a way to:
- Detect developing blockages early before they become a negative impact.
- Prioritise high-risk areas such as known pollution or flooding hotspots.
- Shift from a reactive to a proactive approach to achieve scalable risk reduction.
THE SOLUTION
StormHarvester provided the analytics for the DSV programme by integrating its machine learning platform and hyperlocal rainfall prediction technology into Anglian Water’s operational systems.
StormHarvester deployed over 50,000 sensors across Anglian Water’s network, while monitoring sewer behaviour, identifying early-stage blockages and establishing restrictions before they became critical. These insights were actioned by Anglian Water’s reactive and proactive teams, enabling smarter decision-making and targeted intervention.
RESULTS
- 5,123 proactive interventions, preventing blockages from escalating.
- 70% accuracy in predicted blockages, providing reliable, actionable insights.
- 729 alerts in pollution-risk areas and 4,394 alerts in flood-risk areas.
- Expansion to 42,000 monitors, leading to a 418% increase in blockage clearance.
