Hello All,
Time for an update on WINEP Great Ayton STW Storm Capacity:
After a re-jig of the programme to free up some work for our civils gang we have completed the interceptor chamber. This comprised cutting the existing storm overflow pipe out, constructing the weir wall from reinforced concrete, then benching out the chamber to ensure the wastewater flows in the directions we need it to. We have bunged off the inlet pipe from here to the new storm tank as part of that pipework is not in place and the storm tank/shaft is still being worked on.
We have agreed a solution to correct the issues with the shaft and that is now well underway. Due to the ovality of the shaft a new liner is to be poured inside the structure to guarantee its structural strength. This will be done in two pours. The reinforcement for the first pour is complete and the formwork progressing well, so that we hope to have a concrete pour early next week.
The dewatering continues to be in operation with EA agreement. We hope to be in a position to switch this off by the end of August.
All major design work is now complete and pending review. This will soon allow all major remaining procurement to get underway and further specialist sub-contractor to commence their works.
Thanks for taking the time to read.
Dave Eden PM.
