Project Findings

"Leaky pipes can allow contaminants into our drinking water"

Contaminant Ingress in Distribution systems (CID) has explored the possibility of drawing pollutants into pressurised water distribution pipes due to dynamic hydraulic conditions. This is directly relevant to drinking water quality and hence of importance to public health and wellbeing. The project has, for the first time, conclusively proven that contaminant ingress can occur. While the dynamic hydraulic conditions required are extreme, they can occur within real water distribution systems. This has been achieved through a programme of sophisticated experimental study using an internationally unique physical testing facility developed at the University of Sheffield. The facility is full scale and representative of real system conditions, in particular the surrounding soil and water. Demonstrations using the facility have, and continue to be, vital to the relevance and impact of the completed and future research.

Practical Messages and Insights

Following the completion of the project, a concise poster summarising the key outputs from the investigation was produced. The main aim of this document was to disseminate the new insights and practical messages developed through the work to a non-academic audience; specifically the industrial collaborators.
