Flooding inside your property
Internal and external sewer flooding is caused when sewers become overloaded as a result of severe weather, equipment failure, blockages or sewer collapses.
Internal sewer flooding is one of the most distressing service failures for a customer and reducing it is a very high customer priority.
Flooding caused by assets which are beyond the our control is excluded, eg, fluvial and coastal flooding.
This strong performance and reduction in time is attributable to a number of schemes we have implemented in previous years.
