AMP7 - Internal Flooding

At the start of AMP7 we have been investigating the flooding root cause for a total of 97 properties suffering from sewer flooding. Combined, these customers have reported flooding to their properties on 292 occasions. ​These investigations will help form the basis of upcoming flooding programmes containing schemes identified for delivery on site. ​ AMP7 will see a new approach to the level of flood protection provided to the properties for flooding schemes in delivery. Rather than providing the traditional 1 in 30-year return period property protection at every location in order to remove properties from the flooding register, sometimes leading to higher scheme costs for relatively little additional benefit, a risk-based approach will be taken. ​ We will be assessing the options to resolve the flooding for various degrees of flood protection and providing more cost-effective solutions which significantly reduce flood risk to properties. The money saved will enable more flooding customers to benefit from schemes that might otherwise be unaffordable within the programme budget, driving improvement in Welsh Water’s flooding performance and helping with its aim to be one of the top performing water companies for flooding in the UK.
