Update by Dave Eden
Hi everyone,
Spring has sprung and we’re still moving forward with the refurbishment at Hexham STW.
Works to repair and re-waterproof the existing distribution chamber have reached a point where the chamber can be brought back into use rather than relying on expensive temporary pumps. The final epoxy coating is still to be done, but this requires a number of consecutive dry days so we will come back to that later in the year.
The Detritor is being reinstalled as I type, though the whole process will take a couple of weeks. Anyone nearby may be able to see the crane lifting the newly refurbished and re-painted pieces into place.
Work at Peth Head SPS to alter the pump set up and thereby smooth out the flows was completed last week. This should make the STW run more efficiently by providing more constant flows into the site rather than stop/start.
Construction of the 2nd recirculation manhole is complete ready for the seeding of the new filter which is expected to start WC01/04/24. The seeding could take up to 20 weeks, but it is hoped to be complete much sooner.
Work on the new inlet works is also underway. We have excavated down and broken out some old concrete structures, installed ducting and stoned up ready for blinding concrete by the end of the week and formwork reinforcement and concreting to start in the near future.
As mentioned previously, the continuing traffic management outside the site is not part of our works and is controlled by another contractor - emergency numbers should be displayed on the traffic management signage.
I’ve attached a few photos to illustrate progress on site.
Thanks for taking the time to read the update.
