American Society of Civil Engineers article shows the utility of extensive turbidity monitoring using HydraClam®.

A recent paper published by The American Society of Civil Engineers (ASCE) concludes that turbidity monitoring at high temporal resolution is a necessary tool in furthering an understanding of the discolouration process that occurs in water distribution networks.

The peer-reviewed article, “Need for and use of high-resolution turbidity monitoring in managing discolouration in distribution,” appeared in the Society’s publication, Journal of Environmental Engineering, in June this year.

The research conducted by Dr. Stephen Boult from the University of Manchester and Dr. John Gaffney from Siemens Water Technology shows that turbidity measurements at high temporal resolution taken from several sites within a water distribution network provided a more complete record of the variability of turbidity than previously possible, showing that there are frequent movements of sediment at low concentrations.

Knowledge of the availability of sediment was shown to be important to the prediction of turbidity, as the correlation of hydraulic disturbance (indicated by pressure change) alone with changes in turbidity was weak.

These data sets also showed with greater confidence than previously possible that mains flushing frequently results in the incomplete removal of sediment.

Turbidity and pressure was measured using HydraClam® - a continuous water quality monitoring technology developed by Salamander Group in association with Siemens Water Technologies.

This research was funded by UK’s Engineering and Physical Sciences Research Council as part of an ongoing collaborative research program with the University of Manchester, Siemens Water Technology, and Salamander Group regarding the utility of high-resolution monitoring networks for managing drinking water supply systems.
