Afternoon All.

Time for an on the Great Ayton STW Storm Tank:

Our specialist sub-contractor is progressing the shaft for the new storm tank. The cutting ring and first normal ring are in place and the jacking collar complete. The jacks are in place, and we should start sinking the shaft tomorrow when the long reach excavator arrives. The collar and the jacks give us control of the shaft as it sinks, guiding it and allowing us to keep it plumb.

We are also continuing various trial holes on site looking at the possibility of a streamlined solution. The potential solution is difficult and may prove to be unworkable, but the potential benefits mean we need to at least examine the possibility.

Thanks for taking the time to read this update.

Afternoon All.

Lets get up to speed with progress on the Great Ayton STW Storm Tank:

After the repairs to the surface water main and some assistance from the farmer it looks like the worst of the localised flooding has been addressed.

The access road and working area in the field immediately East/South-East of the treatment works has been completed. This involved erecting a perimeter fence to the work area, stripping the topsoil and laying geo-grid soil reinforcement and stone to create a robust access road and work area. The geo-grid soil reinforcement allowed a reduction in the thickness of the stone and so financial and environmental savings. Stone we don't use doesn't have to be produced or delivered.

Following the Christmas break, our specialist sub-contractor has arrived on site to commence installation of the shaft which will act as the new Storm Water Storage Tank. We have hit the ground running and hope to have the first two rings and jacking collar in place early next week.

We are also continuing a number of site investigations, from trial pits to duct surveys and ground water monitoring, to ensure we installing the most efficient solution possible.

That's all for now, thanks for taking the time to read and please have a look at the attached photos.

Hi all.

I'd like to take this chance to introduce myself; I', Dave Eden the Esh-Stantec Project Manager who will be running the construction of the new storm tank for Northumbrian Water.

We started on site on 28th of October, setting up site cabins, fencing and general work areas.

Since then, we have repaired an existing surface water main which was damaged prior to our arrival. The main was both damaged and blocked and as such was contributing to localised flooding immediately outside of the Sewage Treatment Works (STW). The main is now free running so we should see an immediate improvement. Perhaps Storm Bert will give us a demonstration.

We have also carried out a number of investigations in the form of trial holes and pipe tracing to ensure the new storm tank and associated pipework do now impact on the existing services and structures. These will likely be ongoing intermittently for some time.

As of this week we have agreed access with the landowner for the field immediately east of the STW, so we have started installing temporary fencing and stripping topsoil with a view to installing a stone access road and works area that will give us the room we need to install the new storm shaft. The shaft itself will be inside the existing STW boundary.

That's all for now, thanks for taking the time to read and please have a look at the attached photos.
