Hello All,
Let's get up to date with WINEP Great Ayton STW Storm Capacity.
The Interceptor Chamber Works are complete for the time being; the main structure is constructed and backfilled. We are not intending any works in this area until the back end of the job when we will cut out the storm overflow pipe currently running through the centre of the chamber, build the weir wall and bench out (sloped concrete to aid drainage). This work will divert any further storm flows into the new storm tank, but obviously this can happen until the tank/shaft is complete.
Unfortunately for the shaft works, the previous assessment of the damage caused by the unexpected boulders was optimistic and the damage is more severe than predicted. This, combined with ongoing effects of that damage and possibly other boulders affecting the shaft from outside during further sinking of the shaft, has caused the shaft to deform out of tolerance. We are currently looking into best options on how to correct the issue.
The dewatering continues to be in operation but with reduced flows.
Whilst all major design issues are now complete or near so, further work has been paused whilst we investigate and design the solutions to the shaft issue. This solution may have knock on effects meaning some associated items need limited redesign.
Thanks for taking the time to read.
Dave Eden PM.
