South Hinksey ‘barrier-ready’ works all but complete

In South Hinksey, the works designed to make deploying temporary defences, should flooding threaten, quicker and easier, are almost complete.

Three flap valves have just been installed on pipes which connect into field ditches. These non-return valves will allow water out from within any temporary barrier but not allow it back in from the flooded area outside.

Elsewhere wide garden gates have been installed, reinforced fences built, and removable fence panels fitted.

A very few minor snagging items remain, but the scheme is otherwise complete and fully ready for temporary barriers. Many thanks to the Vale of White Horse District Council for funding and to the Environment Agency for organising the work – not least to engineer Magnus Williams who has managed the scheme from its inception to its completion. Thanks too to farmer Nick Frearson, and to the horse owners for their cooperation during the works.

South Hinksey sewer flooding

We held a meeting on 20 August 2015 to discuss this, especially in relation to possible temporary bunding of the village at time of river flooding.

Representatives from Thames Water (TW), the Environment Agency (EA) and of OFA from South Hinksey met. We had an interesting and fruitful discussion. These actions were agreed:

Thames Water (TW) to initiate a clean of the box culvert north of the village (by today, 27 Aug, this has already been ordered) and update us further on the work that has been, and still is being, done to considerably improve the pumping station at Littlemore.

TW will consider OFA’s suggestion of a sewer bypass for the village, as part of the ongoing Oxford Catchment Study.

Adrian Porter for OFA will fit a chain and handle to the existing non-return flap valve on the Manor Road surface water outlet to enable manual override if necessary.

The suggestion of a memorandum of understanding between the EA and TW, as to how sewer flooding would be dealt with at times of fluvial flooding, especially if a temporary bund were deployed, will be taken forward by the EA.

Many thanks to Thames Water and the Environment Agency for meeting with us and their very positive approach to the problems.

A flap valve for South Hinksey

7 October 2014

South Hinksey: Oxfordshire County Council Engineers are to fit a non-return flap-valve to a surface water drain where is empties into a field ditch: this will prevent water pouring from the ditch into the street in low-order flood events. The Parish Council requested this, and was supported by OFA. The work should be done this month. Thank you County Engineers.
