Focussing Localised Discolouration Modelling
Resuspension of accumulated sediments in water distribution systems typically only affects a small number of end-users per event, but recurrence is common indicating risks can develop rapidly.
Summary
Flushing is a very effective method to remove accumulated sediments, yet the rate of return, extensive size of distribution systems, aging infrastructure and operational resource limitations significantly restrict benefits and question flushing value. To investigate the value of flushing and deployment of limited resources, it is proposed to use stochastic water demand modelling to accurately identify potential sedimentation zones, such that flushing can be focussed on high risk locations and the removal of material with greatest efficiency (maximum removal with least interventions).
