This project is a means for the water company collaborators to lead
the industry in developing and producing justifiable guidelines for
planning operational and maintenance strategies to manage discolouration.
This is based on an ability to use the validated PODDS model to simulate
discolouration incidents through changes in applied boundary forces
mobilising accumulated material and a developing understanding of factors
determining how assets deteriorate as material layers regenerate.
PODDS III aims to:
o quantify the relative influence of different possible controlling
factors on material accumulation and subsequent mobilisation processes
within plastic potable water distribution systems pipes, under controlled
o undertake field based regeneration trials to validate and further
the findings of the idealised laboratory conditions, including other
o develop a PODDS parameter dataset such that material mobilisation
predictions can be made for transmission (trunk main) pipe systems.
