“When you’re working within a live treatment plant, flexibility is critical. Our teams worked through complex challenges while maintaining a focus on the long-term outcome, building greater resilience and reducing future risks.”
Rob Burchell, Watercare
We’re pumped to have delivered this Watercare Assets Upgrades and Renewals (AUR) project, which involved refurbishing one of four anaerobic digester tanks at Rosedale Wastewater Treatment Plant on Auckland’s North Shore.
Our brief was to drain, desludge and clean the tank so structural and mechanical condition assessments could be completed and necessary repairs undertaken. We abrasive blasted and recoated the entire floating gas holder cover before installing a new plywood and waterproofing membrane roof. We also made mechanical refurbishments and upgrades to pipework and control valves to align to the future Thermal Hydrolysis Project.
We then completed the control system programming and cold commissioning with the Watercare operations team.
As a large volume of the work was completed within the enclosed tank, everyone on our team had extensive confined space and gas detection training. This was high-risk work, so we planned well to keep everyone and the plant safe.
