the final assessment of this research project, the highest attainable
commendation of "Outstanding" was achieved by peer review.
A massive 'thank-you' to everyone involved who made this possible.
Prediction and control of
discolouration events was funded by the Engineering and Physical
Sciences Research Council (EPSRC) at the University
A model has been
developed that describes the processes associated with the discolouration
of potable water within distribution systems. The model has been calibrated
through extensive field trials using novel research techniques and equipment.
Subsequently, it has been incorporated as a Water Quality module within
the US EPANET simulation model (freeware software) and allows the simulation
of discolouration events in response to hydraulic disequilibria within
distribution networks. The model represents a major development in the
understanding of the processes associated with the causes of discolouration
events and may be used by water companies to assess their distribution
operation and maintenance strategies. The model has been shown to be
transferable between networks ( UK, Holland and Australia) and has established
new collaborations with researchers in the US, Canada, Holland and Australia.
Although the funding has now ceased, continuing research is desired
to increase the number of data sets available to further develop the
A poster has been produced to help
explain the aims and objectives of this research, including the companies
involved and initial work. (July 2003)
