Webuid pushes for Clough acquisition.

The Australasian Society for Trenchless Technologies (ASTT) is collaborating with the Australian Tunnelling Society (ATS) and Institution of Civil Engineers (ICE) to present the event.

Taking place on 16 September 2022 in Clarkson, a suburb of Perth, the site visit is complimentary for all ASTT, ATS and ICE members, while interstate or international members can livestream the event remotely.

The Quinns Main Sewer Extension includes the installation of 1,931 m of DN1800 sewer main, including 1,167 m of microtunnelling at a depth of 6 m, 25 m deep vortex chambers and 6 other sewer manholes.

When completed, the project will allow wastewater flows from the main pump stations at Ellenbrook, Jandabup and Neerabup towards the Alkimos wastewater treatment plant.

Contractor Rob Carr has made some innovative changes to the preliminary project design, which previously required 700 m of open trench.

The joint ASTT, ATS and ICE event will provide members and attendees with an understanding of microtunnelling construction techniques and methodologies during the site briefing, before seeing the operations in person.

The details for the event are:

Date: 16 September 2022

Time: 15:00-16:30 AWST – Induction commences at 15:00
