GENERAL PROJECT

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.

Let’s get up to speed on the Hexham STW Refurbishment:

The seeding of the new filter beds is continuing, but unfortunately the first set of external biological samples weren’t quite up to spec, so we’ll continue the process for a while longer. Further samples will be taken this week, with results available the back end of the week after.

The inlet works area is continuing – in addition to the main inlet screens slab we have now completed the MCC slab, the wash-water booster slab and all the ducts and draw pits bar a little tweaking.

Coring into the existing balancing tank has restarted and is hoped to complete by the end of the week despite some minor teething issues.

Installation of the super-structure of the inlet works is still planned to commence early June, but the final epoxy coating of the re-furbished distribution chamber has been re-arranged for a later date due to the ongoing seeding.

Thanks.
