Baseline assessments for 2,529 outfalls and 696 soakaways which are currently Not Determined on HADDMS have been undertaken by Ramboll however, due to the ongoing work to migrate the legacy HADDMS system into the new GDMS system, it is not possible to update HADDMS with these baseline risk categories.

A spreadsheet of the results is available for users to manually look up the baseline. The spreadsheet is available from Help > Downloads, the document name is Baseline risk assessment for Outfalls and Soakaways Feb 2023.

For any queries regarding the spreadsheet please contact support@haddms.com.
