This presentation will provide an update on the project, outlining why the renewal is needed, where the project is currently at, and some of the key engineering and project delivery challenges encountered along the way.
The new outfall will extend approximately 1.5 km offshore from the Awatoto Wastewater Treatment Plant. To reduce environmental and community impacts, the project will use trenchless construction methods rather than traditional open excavation.
Topics covered will include:
- Why the project is needed, including asset resilience, environmental performance, and future service requirements.
- How different options were assessed and the role of iwi, regulators, and other stakeholders in the decision-making process.
- Key engineering considerations, including the marine environment, tunnelling methodology, and hydraulic design.
- Procurement strategy, project governance, and risk management.
- Lessons learned from delivering a complex coastal infrastructure project.
The presentation will be of interest to engineers, project managers, and infrastructure professionals involved in water, wastewater, marine, and major capital projects.
Napier City Council is undertaking the renewal of its wastewater ocean outfall, a critical piece of infrastructure that has served the city since the 1970s. After more than 50 years in service, the existing outfall is nearing the end of its design life and has required increasingly complex maintenance and repairs.
