As part of a wider scheme to upgrade plant to improve reliability, meet current standards and enhance current technology, Utile were awarded the contract by Yorkshire Water Services to deliver a replacement ground mounted gas holder for their Narburn Sewage Treatment Facility in July 2020. We were able to offer like for like replacement membranes and pressure relief valve whilst utilising the existing air blowers and local control panel.

In September 2021, delayed due to restrictions, the 480m3 Sattler, Model B9 117/250 double membrane gas holder was successfully installed, pressure tested and purged back to biogas with minimal process disruption.

To replace the previous ineffective lightening protection we installed new lightening protection masts to BSEN62305, LPS1 rolling sphere method to ensure the complete installation is protected to the highest safety level.
