Hexham STW Refurbishment

We are investing over £4.9 million to improve Hexham Sewage Treatment Works. This investment is being undertaken to address asset condition and performance concerns meeting the demands of the upstream drainage catchment. Undertaking this refurbishment work will improve the sites compliance resilience, reducing the likelihood of future pollution incidents, minimising operator intervention improving site Health & Safety. Our sewage treatment works aids NWL in improving the quality of rivers and coastal waters for the benefit of people, the environment and wildlife.

Update by Dave Eden

Morning All.

Time for another Hexham STW Refurbishment update:

The seeding of the new filter beds is continuing well, with biological sampling results suggesting they will be mature well ahead of schedule.

We are continuing civils works on the inlet works area, currently installing all the remaining ducting and pipework ahead of constructing the 3 remaining base slabs.

We have commenced the works to core into the existing balancing tank with the wall plate now bolted to the wall of the chamber ready for pressure testing before the valve is installed ready for coring to begin. This core will allow us to divert the flows into the new inlet works once they are complete.

The refurbishment of the existing Detritor and grit rake is nearing completion. The equipment is all back in place and electrically connected with a view to bring it back into operation this week.

That's all for now, but as always, there's more information in the photos.
