Sewer flooding and loss of service (restricted toilet use) are the worst results of heavy rainfall and are often linked with surface water and groundwater flooding.
More extreme weather patterns resulting in periods of heavy rainfall, along with the paving over of gardens and the loss of green areas, is increasing the risk of sewer and surface water flooding.
The cost and practicality of resolving internally flooded properties has been rising steadily over the last 10 years. Standard solutions such as increasing sewer capacity have become increasingly difficult to deliver.
What we're doing
We have a five year plan that will help save over 2,100 properties who currently suffer from sewer flooding.
In addition to this plan, we have secured £9m funding to undertake five catchment studies to investigate whether more properties can be protected.
These catchment studies are looking at traditional and new methods to reduce flooding and improve levels of service. In order to do this we are carrying out surveying and monitoring activities as well as talking to customers and stakeholders.
The catchment locations
Our studies are happening in five Sewerage Catchments Brent, Aldershot, Swindon, Ravensbourne Valley, and Oxford.
These areas have been selected on the basis of a wide range of issues which are not all related to sewer flooding.
