SUMMARY:Building the Central Interceptor\, Auckland—Microtunnelling of the Link Sewers'
DESCRIPTION:The Australasian Society for Trenchless Technology is holding a webinar on the Central Interceptor project in Auckland\, and they have very kindly extended the webinar invitation to the ATS. \nThe ASTT is thrilled to be able to continue on with its webinars in 2021 and once again provide this free webinar in lieu of our popular trenchless forums which are presently suspended due to the Coronavirus restrictions. \nThe webinar will be a joint presentation by Stephen Grace and Chris McCarthny both from Watercare Services\, New Zealand. \nAbstract of presentation\nStephen and Chris will describe the project design and delivery of this major infrastructure\, and a progress report on the construction of the 2.1 to 2.4 metre link sewers by micro-tunnelling methods. \nThe Central Interceptor is a new deep tunnel sewer that will provide additional capacity in the network to meet planned population growth and development in Auckland\, provide a more resilient wastewater system\, and mitigate wet weather overflows in central Auckland. The project is an integral part of Watercare’s long-term strategy to effectively manage wastewater within the Auckland region\, to protect public health and the environment\, and to provide for growth. \nThe Central Interceptor tunnel is to be built between Grey Lynn and the Mangere Wastewater Treatment Plant over the next five years. The main tunnel will be approximately 14.6 kilometres long and up to 110 metres below the ground surface. It will cross under the Manukau Harbour approximately 15 metres below the seabed. The main tunnel will be excavated by tunnel boring machine and will have an internal diameter of 4.5 metres. In addition\, two separate link sewer tunnels ranging from 2.0 to 2.5 metres internal diameter and 1.1 to 3.2 kilometres in length respectively will be constructed by pipe jacking. Additionally\, there are 16 shafts and connecting sewers up to 78m deep that will divert flow into the tunnel. \nDate: Thursday 23 September \nTime: 1–2 pm EST \nZoom link: https://us02web.zoom.us/j/82913617021?pwd=TVcvWW1vR2U0TG11L1hCdWNnOWpEZz09 \nIf you experience difficulties in joining this free event\, then please email Jeff Pace\, ASTT Secretary on secretary@astt.com.au for assistance.\nAs an online attendee\, you will be able to attend the webinar from anywhere and will be able to submit questions that will be answered at the end of the presentation.
