This report provides an up-to-date and accessible guide to modelling intermittent discharges (i.e. combined sewer overflows, storm tanks and pumping station overflows). It is aimed primarily at water managers and asset planners in water companies who commission work from specialist modellers and authorise investment plans based on the results. It will also be useful for anyone who wants to gain an overview of current practice in the UK.
The guide describes a four stage process to modelling intermittent discharges: defining the problem, selecting an approach, applying the model, and analysing uncertainty. Each stage is broken down into a series of steps, which discuss critical decision points and summarise current good practice within the UK water industry.
A checklist at the end of each stage highlights key issues to be agreed between those responsible for building water quality models and those that use and interpret the model outputs.
