GENERAL PROJECT

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

Hi everyone,

 

Works are progressing well at Hexham STW Refurbishment, especially now we are getting extended periods of fine weather.

Works to repair and re-waterproof the existing distribution chamber are going well, with some extra labour on site and weekend working to try to get complete while the weather hold. All the repair and much of the waterproofing is finished and we will hopefully be applying the final epoxy layer next week.

We are also busy installing some Ts on the distribution pipework which will allow the filters to be operated without using the distribution chamber should it require further works in the future.

The Detritor continues to be refurbished offsite but is expected to be reinstalled WC 18/03/24.

Work has begun over at Peth Head SPS to alter the pump set up and thereby smooth out the flows coming into Hexham STW. This should take around 2 weeks.

 

Construction of the second recirculation manhole has been put on the back burner until the T’s are in place because we need either the Ts or the distribution chamber complete before we can begin the recirculation.

 

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.

 

Thanks for taking the time to read the update. Please have a look at the attached photos for some more detail.
