PODDS et AL represents a truly treatment-to-tap approach to managing drinking water quality. Extensive collaborative research since 2001 has shown how low-level backgound concentrations of material develops as layers on all pipe surfaces (PODDS) and as localised elevated material (LEMA) deposits. By determining which accumulation and then mobilisation process dominates, sustainable and low-cost hydraulic strategies can be successfully applied*. 

To support this world leading research and the pioneering work in network management, operational tools and models are freely available on this website. The recurring nature of consumer observed discolouration however highlights there is much work to de done. With 11 UK companies partnering in this latest PODDS et AL project, the collaborative, real-world approach will deliver detailed and evidenced  process understanding that will continue to inform further transformation and service improvements.

*Working with UK water companies, it has been shown discolouration can be sustainably managed by non-disruptive pro-active hydraulic conditioning. Application of the research to 2,686km of trunk mains between 2015-2020 delivered over £411m savings in operational and capital expenditure. REF 2021.
