Sewer flooding in South Hinksey

It is not uncommon for residents of Kennington, North Hinksey and South Hinksey to suffer from sewer flooding problems and these continued over the Christmas period with surcharges occurring on both the 24th and 27th December. Both dates coincided with the heavy rainfall events and result from Littlemore Pumping Station being unable to cope with the high volume of water.

The second surcharge was particularly challenging for South Hinksey residents as the EA flood barrier prevented the sewage from leaving the village. Thankfully the pumps the EA had already provided prevented houses from being flooded, but they couldn’t stop a pollution incident as the sewage discharged into the local water courses.

Several residents reported the incident to Thames Water, but their response time was well short of their two-hour target. We know of one call which was responded to eleven hours after being reported, and another which took a whole three days. We’d be interested in other readers’ experiences.

OFA Steering Group member Adrian Porter has once again raised the poor level of service with the Thames Water customer liaison team.

Christmas 2020 flooding

Residents in Wolvercote, West Oxford, North and South Hinksey and Grandpont witnessed significant localised flooding on Christmas day after a rapid rise in river levels over the preceding days. Between the 17 and 22 December, more than 25mm of rain fell across the upper parts of the Thames catchment resulting in high river levels on the Thames and the three main tributaries feeding the Thames – the Evenlode, Windrush and Cherwell. An additional 20-60mm of rainfall fell between the 22 December and the 24 December on the already saturated Upper Thames catchment causing a rapid rise in river levels on the Thames in Oxford. The large volume of water discharging from the Cherwell to the west of Christchurch Meadows, is thought to have caused flood water further upstream in Oxford to back up, contributing to a faster rise in levels than we typically experience in the city.

After peaking on Christmas day levels fell, but further rainfall on Saturday night nudged levels back up. The rivers seem to have stabilised since and levels are expected to fall in the coming days. The peak level of the recent flooding was significantly higher than those seen during last winter’s flood events. The Environment Agency has been actively monitoring the situation and flood barriers were erected in South Hinksey as a precaution. Flood Warnings were issued for Wolvercote, and for the New Botley – North/South Hinksey – Grandpont areas. There have been no reports of properties in the city flooding.

The speed at which river levels rose on Christmas eve is particularly concerning, as this limited the amount of time available to deploy defenses. This has potential implications for future flood management planning.

Peter Rawcliffe

It is with great sadness that we report the death of Peter Rawcliffe on 14 December 2020. Peter was a founding member of the Oxford Flood Alliance and he played a pivotal role in the organisation throughout its history. He did a great deal to advance the interests of flood affected communities in Oxford. Peter was a thoughtful and courteous individual, always willing to listen to others’ views. But also a forceful and determined advocate for what he believed to be right. We owe him a great deal. He will be greatly missed.
