The report contains the proceedings and output from a water industry workshop held in London on 8th July 2013.
The purpose of the workshop was to review companies' progress in implementing DOMS since the requirement was first introduced in 1998, to consider the implications of more recent developments such as Drinking Water Safety Plans, and to identify future challenges for the industry. Following an overview of the current state of regulation from the Drinking Water Inspectorate, six presentations on various aspects of DOMS implementation were given by water industry practitioners and these are included in the report.

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.
