Tools for the DOMS Forward-Looking Approach
Price: £500
Ref: 08/WM/18/5
ISBN: 1 84057 509 3
Published: 2008
Previous studies to forecast discolouration potential of water networks have applied traditional statistical techniques such as regression analysis, and detailed process modelling. Such models have generally been hindered by insufficient data or quantification of the underlying processes and hence this project aimed to take a simpler approach that would work with current data and knowledge.
An index approach was developed, using data currently collected by water companies to generate three indices for water quality, vulnerability of the network, and hydraulic discolouration potential. A system discolouration index was calculated at water quality zone level, from the water quality and vulnerability discolouration indices, also including the hydraulic discolouration index when suitable data were available.
The index methodology was delivered in a spreadsheet tool, allowing users to set up the index calculation, import a range of data, and assess the discolouration potential of each zone or other area being studied. Individual zones may then be reviewed and interventions specified, with the tool compiling a list of zones, interventions, timings and costs.
