GENERAL PROJECT

Washington Sewage Treatment Works Refurbishment

As part of a £14 million investment, we will be carrying out work to improve the performance and reliability of Washington Sewage Treatment Works. This work will ensure it continues to provide the highest standards of service for the local community.

Update by Gabrielle Ward

Good Afternoon,

We wanted to post a quick update and let you all know how work has progressed on site since our last update.

Construction works at Washington STW are progressing well. At the new final settlement tanks the backfill operation is  over 80% complete. The run of good weather has allowed us to utilise the as dug clay material which we excavated and stored on site back in October 2020. We have also been busy at the inlet having installed and commissioned the first of three new screen handling units. Electrical upgrade works have continued on programme and we now have 4 out of 5 new MCC’s (Motor Control Centres) installed and commissioned.

Looking ahead we will be removing the temporary works at the Final Settlement Tanks and then moving onto the next phase of works in that area which involves installation of the remaining drainage infrastructure, Manhole chambers and a new pump station. We would like to make you aware that while we carry out this stage of work, you may notice a slight increase in noise coming from the site during working hours. Concrete modifications will be completed at the inlet to accommodate screens 1 & 2. The electrical upgrade and commissioning element of the scheme will continue as programmed. The photographs highlight works at the Final Settlement Tanks and show the new screen handling unit at the inlet.

As always, we would like to thank you for your patience and cooperation during this time.

Gaby
