The PODDS model, developed by the Pennine Water Group
at the University of Sheffield has been shown capable of predicting
the discolouration response of distribution networks to changes in hydraulic
conditions. Results highlighting the capabilities of the full model
are presented in Figure 1. The model is based on the novel application
of cohesive transport theory and its development has led to a step change
in philosophy and perception relating to discolouration. The initial
PODDS research project however did not include development of the model
into a tool suitable to be readily utilised by the water industry. Practical
application is limited by the scope of the parameter dataset and the
time required to apply the full model to complex networks.
This project is therefore a way for the project collaborators
to lead the industry in developing and producing a practical tool for
planning discolouration related operational and maintenance strategies.
