Good afternoon All, where has our summer gone!!! Its been a few weeks since I posted a portal update on the progress of the works that are being carried out on Allendale treatment works, so I thought I would let you know how we are getting on. We have now poured the infill base along with the wall and the precast inlet works have been installed, this is where the new inlet screen which removes grit and solids before flows pass through the RBC, a RBC is a rotating biological contactor which is a fixed-film treatment process used in the secondary treatment of wastewater following primary treatment. You may have also seen a very large crane being delivered last week this was used to lift into position the new pre cast inlet works. We have also poured the concrete surround for the SPEL tank which is a large tank for the storage of the sewerage. We are making good progress with very little disruption so things are looking good. I would like to thank you for all for your continued co-operation and patience while the works progress. If you have any issues or questions please leave a comment below or use the details provided to contact us and we will be happy to help. thank you Julie

Hi Everyone, Hope you are all well?? Here is an update on the progress of the works carried out on treatment plant over the past month, we have sucessfully poured the base for the Rotating Biological Contractor 1 (RBC) We have also had the installation of Motor Control Centre (MCC) & Northern Power Grid (NPG) Kiosks and they are now up and running. As you can imagine because of the weather we are currently having, we have had a few issues with groundwater in all the excavations but we have now got overpumping put in place for anything deeper than 2m and we have came accross a few boulders which have caused issues and delays with the SPEL tank, but nothing we cannot overcome. We would like to thank you all again for your continued co-operation and patience as I know the extra traffic can be a bit of an issue while entering site but hopefully we are not causing to much disruption, in the meantime if you have any questions or issues please leave a comment below or use the contact details provided Thank you Julie
