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

Time for another Hexham STW Refurb update:

The over pumping is now in place to recirculate the flows coming through the new filters into the old filters so that the wastewater is fully treated whilst the new filters are seeded. This process could take 4-5 months but given the warming weather we hope the bug will establish themselves much sooner.

The structural repairs to the Detritor are complete and we are looking to reinstall the refurbished grit rake 1st May and commission the entire kit soon after.

Masonry repairs to the distribution chamber have been completed. Helical bars were grouted into the mortar between the bricks to tie the whole structure together and reinforce areas of cracking then the whole structure was repointed.

Looking forward we’ll turn our attention back to the inlet works area, installing further ductwork and slabs for the MCC, compactor and wash water booster. We will also core into the existing balancing tank for future connection to the new inlet works.

Thanks for taking the time to read and have a look at the attached photos for further information.
