designed for this purpose. Based on the principles of • Options for using different runoff models.integrated modelling, as described in the Urban Pollution

Management (UPM) Manual, its key features are:

• A fully integrated model of CSOs, storm tank, WwTW

and river reach.

• Minimum data requirements - saves time.

• Concise on-screen results output showing:

• CSO spill frequencies and volumes

• storm tank spill frequencies and volumes

• river reach performance against Fundamental

Intermittent Standards (FIS)

• river reach performance against percentile

standards.

• Simulations take only a few minutes and can be• Continuous, rapid simulation over multi-year periods readily repeated with different assumptions. Each

rainfall can be tailored to regional patterns. run generates a results file that can be printed to

provide a full audit trail.• User-friendly interface - easy to use.

WRc's UPM-RAT will be of interest to both Utilities wanting to develop upgrading proposals andEnvironmental Regulators who wish to check the acceptability of such proposals.
