A water company is confident work carried out in Oxford and across the county will reduce the risk of flooding.

Although much of the flooding a year ago was caused by rivers bursting their banks, in some cases sewers overflowed.

Thames Water says it has since identified the causes of sewer flooding and identified parts of the system which are too small to cope during floods.

Monitoring equipment was put in pipes and CCTV images studied.

In Marston, Oxford, which has been badly affected in the past, Thames Water has changed the way the pipes are connected, and cleaned the sewers.

Sewer cleaning is also being carried out at Botley, along with CCTV surveys and flow monitoring work.

At Launton, near Bicester, 15 properties are set to benefit from a £1.2m scheme to replace 230 metres of sewer with a pipe almost four times wider. Work is expected to be finished by March.

The company has also carried out a £400,000 scheme in Abingdon, and upgraded Bucknell pumping station in Bicester.

Jonathan Hiscock, Thames Water's catchment manager for Oxford, said: "The improvements we have made to the sewer network across the county will help reduce the risk of future sewer floods, and our investigations are still going on in a number of areas."

Thames Water staff will be at Oxford City Council's north Eeast area committee meeting on February 17, at New Marston First School, Copse Lane, at 6pm.
