In order to commencing the tunneling process on the North West Wastewater Connection, in previous week TBM Bessie Rouse was commissioned by Sydney Water.
Excavating 800m at depths of up to 27m, this TBM is named after local pioneer Eliza Ann Rouse,whereas the new pipeline is due to link the Taylee Place pumping station to the Rouse Hill Water Resource Recovery Facility.
The value of TBMs that Water Corporation is assembling in Western Australia for Alkimos Seawater Desalination Plant (ASDP) is A$2.8bn (€1.56bn).
With the aim of constructing a 2.5km intake pipeline and a separate 4km outfall pipeline up to 13m beneath the seabed, the TBMs will excavate through rock, sands and clay and install 32,000 concrete segments during take 18 months.
Providing drinking water to over than 2.5 million people, ASDP’s first 50 billion-litre stage will decrease ressure on climate-impacted groundwater sources.
According to Water minister Don Punch: “Desalination was fundamental to water security in Western Australia but also emphasised is on the need to be waterwise. With large parts of southern WA experiencing some of the driest years on record, it’s up to everyone to make sure we use water, our most precious natural resource, as responsibly as possible.”
