Durham City Sewer Network Improvements

We are planning work to improve the performance of the sewer network in Durham City and improve your environment.

Update by Sarah Jayne Vickers

Good afternoon all,

After successful completion of our surface water separation scheme and flow control chamber that formed phase 2 of our essential works in Durham; we are now due to commence the Third, and final phase, Walkergate and Old Elvet Storage.


This week we have started removal of existing feature fencing and replacement task fencing at Walkergate, off Freemans place where we will be looking to install a new Combined Sewer Outfall (CSO) to mediate flows in the network. This will be equipped with a weir wall, a penstock valve and static screens to help achieve outputs governed by the Environment Agency (EA) and to hit a committed target of decreasing spills by April 2021. You should see the rather handsome Heron stature ‘take flight’ in the next fortnight as we remove it to a temporary nesting site within the old Durham Light Infantry museum whilst we carry out these essential works. We hope that the works at Walkergate will take around 14 weeks to complete and will include some nightshift work as we cross Freeman’s place and carry out some delicate work around live services and with live flows. We’ll keep you posted on this accordingly.

Old Elvet Storage

Moving onto Old Elvet, we’ll be taking possession of the roadside closest to the Royal County Hotel from Monday 10th August in order to install some 1200mmØ storage pipes. We’ll be adapting the current traffic management carried out by Balfour Beatty and Durham County Council to form 3-way traffic signals whilst we carry out these works which we expect to take around 12 – 14 weeks, click here to view the TM plan. Hopefully the ground won’t throw up as many surprises as the most recent endeavour, which despite its challenges has finished ahead of schedule – Thank you very much for your patience whilst we’ve been here, and hopefully we’ll leave with a few more successes under our belts and many more friends.

As ever, please don’t hesitate to get in touch at or or alternatively us the contact us link at the top of this page.
