49.This section requires Scottish Water to prepare assessments about sewerage flooding for the potentially vulnerable areas identified under section 13 and for other areas identified by SEPA. SEPA must consult Scottish Water and other responsible authorities before identifying other areas for which assessments are required.
50.Each assessment must identify where floods are likely to originate from sewerage systems in the area and must estimate the volume of sewage which is likely to be released in the event of such floods. It must also include any other information specified by the Scottish Ministers in regulations. Before making such regulations, the Scottish Ministers must consult SEPA, Scottish Water and any responsible authority they consider appropriate.
51.Subsections (4) to (6) provide for SEPA to determine the form of the assessment so as to ensure that the data can be integrated with other information on flood risk. SEPA must consult Scottish Water and other responsible authorities before making this determination.
52.Subsections (2) and (8) enable the Scottish Ministers to set the dates by which assessments must be prepared, reviewed, and, where appropriate, updated. Assessments must be then be reviewed and, where appropriate, updated every 6 years.
