NBIC proposal with Welsh Water

Influence of phosphate dosing to prevent plumbosolvency on biofilm formation in drinking water distribution systems (iP3Bio).

CIV Mappin

The aim of this project is to facilitate novel research investigating the impact of phosphate dosing and lead leaching on drinking water quality and safety. Phosphate is added to control plumbosolvency and corrosion in metallic pipes hence it is used to protect consumer’s health and water quality. Current research is highlighting the essential role of pipe wall microbial biofilms on key processes within Drinking Water Distribution Systems (DWDS), but the impact of phosphate dosing on biofilms remains currently unknown. Considering that biofilms degrade water quality and impact water safety through the potential hosting of undesirable microorganisms, realistic research on biofilm formation in DWDS is essential to understand the factors that influence their development. Currently large amounts of phosphate are dosed into DWDS to control lead-leaching from lead pipes, but there is little information about the surface processes that are involved in the leaching and the interactions with the biofilms in the drinking water pipe networks.
