A micro–Tunnel Boring Machine (mTBM) called ‘Domenica’ has started digging and laying the first pipe for Watercare’s Central Interceptor wastewater tunnel project, Auckland Council announces. The mTBM, which is 12-metre long, laid the first three metre sections of the 2.1-metre diameter pipe at the May Rd, Mount Roskill site on 4 June. Another 328 pipe sections will be installed in the following months. The mTBM will travel up to 18 metres per day with digging to take place 24 hours a day, six days per week to complete the first drive.
