New Lonsdale Street sewer in the pipeline

A new 900m sewer will be constructed along Lonsdale Street, in a $21 million upgrade project to help secure wastewater services for people living and working in Melbourne’s CBD. 

The works, due to begin next month for completion by late-2020, will help City West Water meet the city’s rapid population growth, with a projected 123,000 more people living in the CBD by 2036, fuelled by strong high-rise apartment development.

The project which spans along Lonsdale Street, between Elizabeth and William Streets, will connect with the Spencer Street sewer duplication, which was successfully completed in December last year.

General Manager Infrastructure & Delivery at City West Water, Maree Lang said the project was part of an $80 million capital improvement program to maintain service reliability.

“An increase in the capacity of the CBD’s current sewer network is necessary to deliver efficient, safe and environmentally responsible wastewater services into the future,” Ms Lang said.

“There’s no doubt Lonsdale Street presents us with some logistical challenges given its location and daily use by many city residents, businesses and visitors, however we’ve been planning for many months to minimise disruptions throughout the works period,” she said.

“Importantly, no water or sewerage services will be impacted while work is in progress.”

The project, which will be undertaken in stages, will have some impact on traffic and pedestrians due to lane closures and some parking restrictions may apply.

Over the coming weeks, the community will notice contractors undertaking early works, including the confirmation of existing service locations and ground conditions to help clarify the alignment and design of the project.

In preparation for construction, City West Water has been working closely with Melbourne City Council, Victoria Police, Metro Tunnel Project, Magistrates Court, transport operators and utility providers to reduce the impact as much as possible.

“We’re mindful of the impacts of our work and would like to thank local residents, businesses, commuters and visitors in the area for their support and patience in advance,” Ms Lang said.

The project will be delivered for City West Water by Rob Carr Pty Ltd.

Further information will be available upon the completion of the design phase, before construction commences in September.

Important information for residents, businesses and visitors during the early works period:

·       Works will take place from 9.30am to 3.30pm Monday to Friday. No work will be undertaken on weekends or at night.
