Northumbrian Water

Northumbrian Water provides water and sewerage services to 2.7 million people in the North East of England with 27,000 km of sewers and cleared 9500 blockages in 2019.

StormHarvester and Northumbrian Water have worked together since early 2018 to analyse pumping chambers in Newcastle-Upon-Tyne in Northern England. This discrete network was chosen due to the location of Combined Sewer Overflows or escapes (pollution and flooding) and pumping chambers within the Catchment and past rainfall events in the area.

Three years of data from 12 pumping chambers and Combined Sewer Overflows or escapes (pollution and flooding) were analysed using the StormHarvester Smart Sewer Predictor. The analysis allowed Northumbrian Water to easily visualise their network performance and quickly identify, quantify and rank assets to see how they were performing or if they had particular sensitivities to rainfall.

The results of the analysis determined that on average a 30% reduction in Combined Sewer Overflows or escapes (pollution and flooding) spillages was achievable across the catchment using StormHarvester’s real-time controls.

“The StormHarvester Smart Sewer Predictor allowed us to easily visualise historic data from a section of our wastewater network. It allowed us to assess our network performance and quickly identify sites with particular sensitivities to rainfall. The StormHarvester team were easy to work with and have always been quick to respond and adopt to our particular requirements”
