Rosedale breakthrough

摘要

Auckland's Rosedale Wastewater Treatment Plant Outfall Project has taken a step closer to final completion with the breakthrough of its tunnel section. The NZ$116M (US$81 M) project is the largest ever undertaken by North Shore City Council, and will see the existing 50 year old tunnel and outfall system replaced with new system that will release effluent 2.7km off-shore into waters of about 12m in depth.
