Whitton Village Sewer Diversion

Northumbrian Water is looking to investing £1M to improve the resilience and enhance the performance of the sewer network in Whitton Village Northumberland.

Project updates

Update by Ian Davison

Good afternoon everyone.

I hope you are enjoying this lovely sunny weather, it’s a lot warmer than this time last week.

I am pleased to let you know that we remain on course to commence the site work in the Autumn and wanted to give an update on our construction phasing. Rather than adopting a staged approach the whole scheme will be deliver in a single operation.

We will continue to keep you informed as we get closer to the start date.

Best Wishes

Ian

Hi

 

I hope everyone is well and looking forward to the weekend, I thought I would let you know about a small change to the proposal. This project has been very fluid in its development to this stage and I must apologise for this uncertainty.  The location of the new Sewage Pumping Station has now been finalised and is shown on the latest Schematic posted on the “Planned Works” tab.

 

As I mentioned in last months update letter we will adopt a two stage approach, the extent of each phase of the works is indicated on the sketch. You will note that the pumping station has been repositioned into the field towards the bottom of Whitton Bank.

 

 The Stage 1 works will comprise the construction of a new sewer from Whitton to the pumping station. The construction of the pumping station, wet well, valve chamber and the compound. The wet well and valve chamber are below ground structures.

 

 The Stage 2 works will comprise the mechanical and electrical fit out of the SPS and the installation of the disposal rising main to connect the new pumping station into the Rothbury catchment.  

 

We are working towards commencing the Stage 1 works in the autumn, the stage two works are currently planned 2020/21. In the interim period we will be tankering flows from the SPS constructed during Stage 1 of the works.

 

Have a great weekend.

Hi, I hope you all remain well and apologies for not being in touch for a while

You may remember that in September last year I provided an update about the work we were planning to undertake in Whitton. I promised to keep you up to date regarding this  proposal.

I mentioned that our design team had identified a solution that would see a new sewer installed within Whitton Bank, with a new package treatment plant and outfall sewer to the river Coquet. We were planning to commence these works in the late spring of 2019.

Further information has come to the design teams attention during our investigations which we had to consider. The package treatment plant solution outlined is no longer viable and an alternative pumped option is now under review.

I want to share our new proposal with you to understand your views about this alternative option and agree how we can minimise any disruption that you and your community may experience once the work is underway.

We are proposing the construction of a new pumping station, rising main and gravity sewer. I have posted a plan (Schematic Plan March 19) on the “Planned Work Tab” which shows the areas that we propose to be working in. The work will be delivered in two phases and there will be an interim period where tankering of flows will be necessary.

The project team are now working towards commencing the phase 1 construction work in the autumn of 2019. The phase two works are currently planned for 2020/21. It is unlikely that driveways will be blocked while undertaking the work however if it is necessary to work adjacent to driveways we will contact you in advance to discuss any access restrictions and the appropriate mitigation. 

I apologise for the delay and I will continue to keep you up to date with our plans for this essential work.

Regards

Ian

Hi all

I hope you have had a great weekend. Just a quick note to advise that our contractor will be onsite next week excavating trial holes to establish the location and level of existing services along the route of the proposed sewer. This work will involve the use of machinery to excavate a shallow inspection trench within the road and verge to expose and record buried utility cables and pipelines. The location of the trial holes are show on the plan posted on the planned works tab and shown on the photo below. Traffic management will be required and the highway will be fully reinstated upon completion.

This work will take up to 7 working days, within this period we will also be undertaking a geotechnical investigation which will allow the engineering team to assess the ground conditions within which the new sewer is proposed. Once we are on site, if you are going to be directly affected by our work, our site team will contact you in advance. The site team will do everything they can to minimise any inconvenience caused by this and will make sure that the work is carried out safely. Upon completion the land will be reinstated back to the original condition

Thanks

Ian

Hi

You may remember that we wrote to you in January to give an update about the work we were planning to undertake in Whitton. We promised to keep you up to date regarding our proposals.

In my previous letter, I mentioned that the issue to be addressed was complex and the scale of the works required was significantly greater than first anticipated. As a result, the works were rescheduled within the capital plan and programmed to commence during the financial year 2019/2020.

The design team have now identified a solution to ensure that our sewer network continues to protect the environment and serve the community effectively. We want to share our new proposals with you to understand your views about this work and how we can minimise any disruption you and your community may experience once the work is underway.

Our proposed work will see 575 metres of new sewer pipe installed within the highway and verge. A new package treatment plant and outfall sewer to the river Coquet will also be provided. We are planning to commence these works in late Spring. A plan is posted on the "Planned Works" tab.

I would like to hear from you if you have any feedback about our proposal, please leave your comments on this update, or get in touch using the ‘Contact us’ button at the top of the page.

I apologise for the delay in the implementation of these works however, I will continue to keep you up to date with our plans for this essential work

Regards

Ian

Hi All

On my previous portal update I mentioned that the design team had identified that the diversion of the combined sewer into the Rothbury network will marginally increase the downstream flood risk. Additional analysis has highlighted that the issue is complex and the scale of the works required to address the hydraulic detriment is significant.

As a result, the sewer diversion works have been rescheduled within the capital plan to allow the team sufficient time to identify a suitable solution. This work is now programmed to commence during the financial year 2019/2020.

I apologise for the delay and I will continue to keep you up to date with our plans for this essential work.

If you require any further information or advice please contact our Customer Centre on 0345 717 1100 or visit www.nwl.co.uk to request a call back from the project team.

Regards

Ian

Hello Everyone

I hope you all remain well, I wanted to touch base with you all with an update on the design work within the last month or so.

The design team are continuing to work on the sewer diversion between Whitton and Rothbury. The ground investigation is complete and the scrutiny of the network performance continues. We have identified that the diversion of the combined sewer into the Rothbury network will marginally increase the downstream flood risk. We have to ensure that any work undertaken in Whitton does not increase flood risk elsewhere therefore, the scope of this project has increased to ensure that there is no downstream detriment.

This analysis will take additional time to complete and we do not anticipate commencing the construction works until Spring of 2018.

I will continue to keep you up to date with our plans for this essential work and will be back in touch to confirm the construction dates when the  investigation is complete.

I would still like to hear from you if you have any feedback about our proposal or want to make us aware of any drainage issues in your area. Please leave your comments on this update, or get in touch using the ‘Contact us’ button at the top of the page.

Kind Regards

Ian

Hi

Just a quick note to advise that our contractor Dunelm will be onsite next week excavating trial holes in the field between Whitton and Rothbury. The work is planned to commence on the 12th October and should be completed within a couple of days.

This is a geotechnical investigation which will allow the engineering team to assess the ground conditions within which the sewer diversion is proposed. Upon completion the land will be reinstated back to the original condition.

Thanks
