Melbourne Water is set to commence relining works on the North Yarra Main Sewer, a sewer that transports sewage from Melbourne’s north-east to the Western Treatment Plant.
The works are scheduled to start on Wednesday 3 April and are expected to take five to six weeks to complete. WOrks will be completed as part of night works between 7pm to 6am, Sunday to Thursday.
Melbourne Water will use relining as it will allow the utility to reline the inside of the existing sewer with new plastic sleeving, ensure that disruptions are kept to a minimum, allow upgrade works to be completed more quickly and efficiently and ensure the structural integrity of the sewer is maintained for decades to come.
The North Yarra Main Sewer was first constructed in the early 1900s with some sections now coming to the end of their working life.
In October 2023, Melbourne Water began major construction works to rehabilitate the upper section of the sewer. The total rehabilitation works include:
- Cleaning, scanning and relining the sewer
- Constructing temporary and permanent access tracks to maintenance holes
- Rehabilitating ageing and damaged maintenance holes
The lower section of the North Yarra Main Sewer from Yarra Flats Park, Ivanhoe East to Farm Rd, Alphington will be relined as part of a later project, which is planned for 2024 or 2025.
