Work began in early 2013 on a £1 million programme to tackle the problem of high levels of groundwater flooding the sewer network in villages along the Nailbourne river.
While it's the role of other agencies to investigate groundwater flooding problems, our priority is to ensure customers can continue to use their sinks and toilets.
In some locations we used new biological treatment tanks which can improve the quality of floodwater pumped from our sewers by as much as 40 per cent.
Our film explains in more detail how these tanks work.
In 2013, engineers used remote operated CCTV cameras to extensively survey over ten kilometres of sewers and 250 manholes.
Sources of groundwater infiltration were identified, which in extreme conditions can cause sewer flooding of homes and gardens.
Significant infiltration was found at the following locations:
Work started in September to repair over 3.5 kilometres of sewers. The project is part of a £6 million region-wide scheme to address groundwater flooding of sewers following heavy rain in 2012, which was the wettest year on record throughout England.
We're working closely with authorities such as parish, borough, district and county councils, the Environment Agency and river management groups to jointly resolve the problems caused by groundwater flooding.
