Demonstrating fruitful cooperation, representatives from the River Deben Association, Deben Climate Centre and Anglian Water - Love Every Drop walked the bank of the Deben Estuary from Martlesham Creek to Wilford Bridge on Wednesday morning. (With thanks to Martlesham Creek Boatyard for parking).
The focus of the expedition was mapping all the outfalls and sluices which belong to Anglian Water, the Environment Agency, East Suffolk Council and private owners. Our Anglian Water colleagues shared maps of each of the Combined Storm Overflows (CSO’s) on the network and we discussed recent spills and how this had happened; DCC are now monitoring these spills and their impact on a regular basis.
The source of one unexplained polluting drain, already monitored by DCC, near Woodbridge railway station, will be followed up and one Anglian Water CSO, currently incorrectly placed on publicly available on-line maps, will be moved to its correct location at Lime Kiln Quay. The high flow, sometimes polluted, stream alongside Kingston Field also drew our attention, with East Suffolk Council contractors repairing drains by the boating pond, long blocked by tree roots…
Our “eyes-on” walk surfaced a number of other questions to which answers can now be sought. These and other issues will be discussed on 12th November at a conference hosted by the Essex and Suffolk Rivers Trust.
Beautiful weather for the walk makes it difficult to understand how these hidden and irregular storm overflow issues happen. At least wild swimmers and other recreational users can be grateful for the estimated 7-17 million litres (per neap and spring tide) daily tidal exchange of the estuary which the participants on low-flow rivers cannot benefit from.
