The construction phase of this project is now complete.

There may still be updates, so the project will remain here. We are still monitoring the project and will reply to any comments. So if you have any questions please feel free to comment or contact us here.

GENERAL PROJECT

Sherburn Upgrade

Starting in 2022, as part of a £12.9 million scheme, we will be carrying out essential work to improve the performance and flexibility of our wastewater network and wastewater treatment works in the Pittington and Sherburn areas of County Durham. The scheme will help to improve the water quality of the Coalford and Sherburn Becks, as well as the watercourses downstream. We are yet to confirm an exact date when the works will commence, however once we do we will contact you to ensure you’re kept informed and made aware of any possible disruption.

Project updates

Update by Bethany Oakley

Good afternoon all,

I hope you've had a good week. 

Since my last update on the portal, we are nearing on completion of the Sherburn STW. The main construction element to the works have now concluded and we only have a small ammount of electrical snagging to complete.

We still have some work to carry out before the Pittington Works can be finished but I will provide a further update on this in due course.

If you have any questions you'd like to ask us or any concerns you wish to raise, please don't hesitate to add a comment in the box below and one of the Project Team will respond. 

Take care,

Bethany

Good afternoon,

I hope you are well and having a great week so far! 

I'd firstly like to introduce myself, my name is Bethany Oakley and I am a Customer Liaison Officer for JN Bentley. Going forward, I will be taking on Sherburn and Pittington works and will therefore be keeping you up to speed with the works and providing updates on the Customer Portal. 

The works are continuing at both our Sherburn and Pittington Sewage Treatment Works (STW) sites as planned.

The existing works at Pittington STW will remain in place for a period of time whilst testing and durability of the new installation is assessed. Once completed we will be looking to carry out decommissioning and demolition works across the site. In the meantime, we are currently reinstating the existing field at the site entrance so that we can hand it back to the landowner.

At Sherburn STW, we are continuing with reinstatement works across site, although the recent weather is definitely not helping us. Footpaths and hardstanding areas are currently in construction and will bring the project to a close on their completion. Some fine tuning is being undertaking on the recently installed equipment across site in order to optimise the processing of incoming effluent.

As always, please leave a comment below should you have any questions, and a member of the project team will get back to you.

Thank you for your continued patience and cooperation.

Good afternoon,

Since we are now back at Pittington carrying out the remaining work, I'll share an update for both Sewage Treatment Works (STW).

Our work at Sherburn is continuing to progress well. As previously mentioned, the site team have carried out the work to the existing site area including pipework upgrades, weir replacement work and the filter bed arms have been upsized. All structures within the STW are now installed with the reinstatement works are due to be carried out including the footpath areas and roads within the site boundary. The new Chemical Dosing Systems are fully operational, and a new flow measurement flume has been built. The HSAF tanks have been cleaned and emptied ready to be removed from site. We are aiming to have the construction work completed some point during April, although a date is yet to be confirmed. I have added some photos for you to view of some of the areas mentioned above.

Over at Pittington, the team are commencing with the pipe connections for the new pumping station, this will then be tested and commissioned. This month, the flows will start to run from Pittington STW down to Sherburn STW. We will also be commencing with the reinstatement at the entrance of the works. 

As always, please leave a comment below should you have any questions and a member of the project team will get back to you.

Thank you for your continued patience.

Good Morning,

I just wanted to post a quick update about Pittington Sewage Treatment Works (STW).

You may have noticed by now that we have returned to the STW to commence with completing our commissioning of the new pumping station, decommissioning and demolition of parts of the wastewater treatment works, and reinstatement of the compound area. This should take around four months to complete. 

Disruption will be kept to an absolute minimum, and your water and sewerage services will not be affected during this time.

If you do have any questions, please leave a comment below and a member of the project team will get back to you.

Thank you for your continued patience.

Good Morning,

It's time for the final update of the year!

Since our last update, the Motor Control Centre Kiosk and the electrical panels have successfully been installed. All electrical works to the MCC Kiosk are now complete.
As mentioned in our previous update, the Mecana (filtration equipment) is also now up and running. The site team are currently carrying out works to the existing site to enable increased flows to be taken from Pittington in the new year.

I have included a video which gives you a birds eye view of the NSAF Tanks that are designed to promote nitrification into the water which significantly reduces the ammonia levels from the effluent. Air bubbles are forced through the tanks as you can see in the video. The oxygenation helps to increase the amount of bacteria in the tank, which then eats the ammonia from the effluent. Once the ammonia levels are reduced, the effluent can then be flowed into the next treatment process. You can view the video here.

We wanted to let you know that the site will be closing down for the Christmas break from Wednesday 20th December until Tuesday 2nd January. 

On behalf of the project team, we would like to thank you for your continued patience this year and we hope you all have a wonderful Christmas and New Year!

Hello!

Since there is currently no construction work happening at Pittington at the moment, this update is focused on Sherburn STW!

Following on from our previous update, the Chemical Dosing Kiosks have now been installed which are shown in the photos below. The team have also completed the footpath and hardstanding areas around the kiosks.
We previously mentioned the preparation works were ongoing ready for the new Motor Control Centre kiosk installation which has been carried out by our subcontractors, Armah. 
The team have water drop tested the new NSAF tanks successfully and poured the concrete floors inside the tanks (as photo). De Nora are on site installing filter stone media and pipework ready for service.
The duct installation is now complete, with the final duct network within tertiary treatment area progressed allowing electrical connection link to be made with NSAF, Mecana and Backwash Tank equipment.

As a thank you to the residents of Sherburn, NWG and MMB have donated a new information board on the history of coal mining in Sherburn. This has been installed next to the memorial tub and bench in the village. If you haven't been down there already, it's definatley worth a visit!

As always, please feel free to leave a comment below should you have any questions and a member of the project team will get back to you!

Speak soon!

Good afternoon,

It's been a while since our last update. Work is continuing to progress well at Sherburn, and you may have also noticed that things are a little quieter at Pittington.

Sherburn

I mentioned in our previous update that work had begun at the Chemical Dosing Area, this has been progressed over the past weeks. The site team have now poured the concrete floor slabs and spill apron which will allow the new dosing kiosks to be installed as planned next week.  
Steel fixing, shuttering and concrete pours have took place to the new NSAF treatment slab. Our subcontractor De Nora have now erected the three new NSAF tanks on site, with a future visit planned for them to undertake mechanical and electrical installations. 
The new Motor Control Centre Kiosk civils work is also now progressing. A pre cast concrete cable trench has now been installed and current works are underway to form the kiosk concrete base slab above; this will allow the kiosk to be placed and site wide electrical works to proceed in the near future.

I have attached some photos giving you a visual of the areas mentioned.

Pittington

If you've recentley passed Pittington Sewage Treatment Works (STW) you may have noticed that the site cabins have been de-mobilised, and things are a bit quieter. This is because we have now successfully completed installing 3.4km of pipeline from Pittington STW to Sherburn STW. Although this section of work has been carried out, we wanted to make you aware that we will need to return later in the year/early next year to carry out the remaining work within Pittington STW. Once we have a confirmed date, I will be putting an update on here, so keep a look out!

In other news, as a thank you to the community for putting up with us, Northumbrian Water and MMB donated paint and painting materials to Pittington Village Hall, and spent the day painting the hall alongside some lovely volunteers from the village. Thank you to everyone who came along and helped, and also a big shout out to Jodie, the hall manager, for the bacon sandwiches! We had a lovely day helping to give this much loved space in the community a makeover.

As always, thank you for your continued patience.

Good afternoon!

I thought I'd let you know how the work at Pittington has been progressing.

As mentioned in my last update, the construction work to Manhole 8 is now complete, along with Manhole 7. The benching works to the Flow Control Chamber has been carried out and the cover slab has been installed. The upstand has now been poured and ready for the security lid, and the risers and steel work is currently underway to the second opening. 

The top soil reinstatements have now been carried out in Fields 1 through to 10, with Field 11 still outstanding!

In Pittington STW, the electrical work is almost complete. The ductive iron pipework to the valve slab has been constructed and the paved walk ways at the SPS have been laid. 

I have included some photos for you to view.

Keep a look out for the Sherburn STW update...

Good afternoon,

It's been just over a month since our last update and a lot has been happening!

Pittington 

Over in fields 10 and 11 towards Sherburn STW, the Flow Control Chamber is now in position and the gravity drainage pipeline from the Flow Control Chamber to the existing manhole chamber has been tied in. The 600mm storage pipe between the Flow Control Chamber & Manhole 11 will be complete this week with reinstatement works to follow.
The construction of Manhole Chambers 10 and 11 is around 80% complete. The concrete base has been installed to Manhole Chamber 8, with the remaining construction work to be carried out. Drilling works previously mentioned back in April from Manhole Chambers 11 to 10 and Manhole Chambers 10 to 8 were successful.
In the upcoming weeks, all reinstatement works in the fields will be underway. 

At Pittington STW, the legato retaining wall and infill wall has been constructed. The rising main pipework is currently being connected and above ground level. The MCC Kiosk has also been installed, and the electrical work is being carried out. The concrete surround to the SPS is also complete.

The pipeline route and manhole chamber locations can be found here.

Sherburn STW

The new deep Backwash Tank has now been completed and a water test undertaken to check for leakages... thankfully it passed! The scaffolding is due to be installed to allow pumps and pipework to be fitted.
We are currently building a pump station for our new NSAF treatment tanks. This is a shallower well which will also contain pumps and pipework.
The majority of new ducting is now laid within the existing treatment works site.
And finally, works have recently begun on the new chemical dosing area. We are removing old foundations and buried structures from the original works in order to accommodate the new site layout.

I have included some photos for you to view.

Good Afternoon,

As part of our work in your area we wanted to let you know about the next stage of our work, in field 10. To create a safe working area to construct man hole 08 we need to install sheet pilling using a hammer method.

This will take place over the next three days, starting Wednesday 17 May and end Friday 19 May. We will continue to use the shared access off Latimer Way to get to this working area. See plan attached.

Thank you again for your patience.
