Case Study: Southern Water reduces sewer overflows with StormHarvester

Southern Water identifies I&I in 25% of overflows with StormHarvester

Southern Water, a wastewater utility, faced the challenge of reducing sewer overflows into watercourses. They needed to determine if these overflows were caused by exceptional rainfall, inflow and infiltration of groundwater, or operational issues. To address this, they partnered with vendor StormHarvester to analyze the underlying causes using their service.

StormHarvester implemented a solution using machine learning algorithms trained on hyperlocal rainfall data for each site. This approach identified that inflow and infiltration was a significant cause, with 25% of overflows occurring at affected sites. The insights gained allowed Southern Water to create a more targeted environmental plan and consider new, sustainable solutions to reduce overflows at their source.
