Update by Gabrielle Ward

Good afternoon,

I'm pleased to be able to confirm that we've substantially completed our sewage treatment works refurbishment at Rothbury STW. The upgrade work included the construction of the following to improve the performance and reliability of the sewage treatment works to ensure it continues to provide the highest standards of service:

  • new inlet works screens and flow control / recording
  • 2 new PST c/w ½ bridge scrapers
  • New auto de-sludge pumping station
  • Full electrical upgrade including MCC panel and kiosk, and a new SCADA computer control system
  • Re-purpose of existing Pumping Station into HSAF Tertiary Treatment PS.
  • Two brand new HSAF units
  • Storm Tank upgrade works to increase capacity.
  • Installation of 2 new recirculation pumps
  • De-commission and removal of old sludge PS and associated pumps and pipework.
  • Installation of new MCERTS flow meter and chamber.

While we have completed all construction work, there are still some minor reinstatements and electrical tie-ins to be carried out. We will be de-mobilising the site compound week commencing Monday 21st November which should take up to a week. During this time, there will be an increase of vehicle movement along Wagtail Road and Mill Lane so please take care if you are in the area. 

I have included some photos for you to view.
