Haven or Hazard?

There was much excitement about recent sightings of otters in the River Roding. It was particularly astonishing given the state of the river, but is a reassuring sign of nature’s resilience, says Councillor Jo Blackman

The River Roding and its tributaries are critical features of Redbridge’s environment and a vital haven for a range of wildlife and biodiversity. They are also valued by residents and form a distinctive part of Wanstead Park and Roding Valley Park, as well as plans for the Ilford Arrival scheme, a Greater London Authority part-funded programme to open up access to the Roding near Ilford, and wider regeneration.

Sadly, the River Roding has suffered similar challenges to other waterways across the country and has some of the highest number of sewage discharges in London, after the Thames. Information on permitted sewage outfalls is now made publicly available on the Thames Water website. 

Recent testing undertaken by Thames21 and the River Roding Trust in collaboration with local citizen scientists shows levels of E. coli and intestinal enterococci bacteria regularly exceeded safe limits during dry weather conditions (sometimes by a factor of over 20). These results are likely evidence of Thames Water spilling untreated sewage in addition to the outfalls authorised by the Environment Agency. Thanks to the work of the River Roding Trust, we are aware of at least two unpermitted sewage outfalls (located on the Aldersbrook and at Little Ilford). Further work is needed by Thames Water to identify any other unknown outfalls in the Roding. 

Thames Water and Environment Agency officials recently appeared in front of the Redbridge Council’s External Scrutiny Committee, chaired by Wanstead Village Councillor Daniel Morgan-Thomas. The real special guest at the committee was the Roding itself. Paul Powlesland from the River Roding Trust brought a container of water from the Roding with him – a powerful reminder that we need to ensure all agencies are acting in the best interests of the river, which has too often been neglected.

Whilst some progress has been made by Thames Water, officials at the meeting were unable to provide the committee with much detail, nor was the Environment Agency able to tell us if they had taken any action against Thames Water for the pollution of the Roding. I have therefore joined forces with Calvin Bailey MP, Chairman of the Epping Forest and Commons Committee Ben Murphy and Redbridge Council Leader Kam Rai in a letter to Thames Water and the Environment Agency demanding urgent action in the interests of the environment, public health and our residents. 

If we want the otters and other wildlife to thrive in the Roding, we need Thames Water and the Environment Agency to step up and take action to address the sewage scandal.
