Simon Collings represented OFA at the second meeting of Oxford City Council Scrutiny Panel on sewer flooding. Thames Water (TW) gave an update on where they are with a) Grandpont and b) the Oxford Catchment Study:
At Grandpont they have identified the most likely causes of sewer flooding and TW will now work with the City Council and residents to improve things. Local resident Brian Durham of OFA and SOFAG has been closely involved in this work.
On the Catchment Study they are engaged in two parallel processes:
- a physical inspection of assets across the city – with any issues they identify being fixed as they go along (where the business case is obvious). This includes an inspection of both main trunk sewers.
- customer surveys to help them understand where problems arise during a flood and how these manifest themselves.
So far they haven’t encountered anything which would suggest they need major capital investments, though they do plan to upgrade the pumps at Littlemore.
TW are talking to the Environment Agency (EA) team working on the Oxford Flood Alleviation Scheme, and the two modelling teams are going to share data and work together. By good luck the option development phases of both projects are working to similar timetables. EA will help TW understand how the river flooding affects the sewers, and TW will contribute to that work.
There will be one more meeting of the Scrutiny Panel in November/December but from then on formal reports will be given through the Oxford Area Flood Partnership, to avoid duplication of meetings.
