The Lonsdale Street Sewer upgrade, a $21 million project to install a new 900m-long sewer main beneath Lonsdale Street, has been completed.
The project is a key part of City West Water’s four stage, $80 million program to expand the capacity of the Melbourne CBD sewer system.
The completion of this project – the second stage of the four stages – will help to secure reliable and vital sewerage services for city residents, visitors and workers for years to come.
A 6.3m-long, 16.3 tonne Tunnel Boring Machine was used to install the new 1.5m diameter wide sewer pipe under Lonsdale Street. The pipe will link to a new sewer under Spencer Street which was installed in December 2018 under stage one.
City West Water Managing Director, Maree Lang, said the completion of the project was a significant step towards securing service reliability and formed part of the biggest upgrade to Melbourne CBD’s sewer network in more than 120 years.
“With the existing sewer over 120 years old, the new sewer pipe will help cater for the growing demands of the Melbourne CBD now and into the future,” Ms Lang said.
“We sincerely thank the thousands of city residents, workers and commuters who adapted to the changed conditions while we carried out construction along Lonsdale Street.
“Your patience and understanding allowed us to provide this vital piece of infrastructure for Melbourne’s CBD.”
Construction work on stage three, which includes a new sewer along Elizabeth Street, is expected to begin in mid-2021.
