Sewerage Network Improvements
Yarra Valley Water's sewerage system has been designed and constructed with significant additional capacity to contain peaks in daily flows and after heavy rainfall.
However, in extreme storm events, wastewater flows can exceed the system’s capacity, resulting in diluted sewage being discharged at overflow points via Emergency Relief Structures (ERS).
We are planning to upgrade two Emergency Relief Structures (ERS) and install screens at three sites to ensure we continue to provide a safe and reliable sewerage service for customers and protect the environment.
Great Ryrie Street Ringwood, ERS
During the June school holidays, we will be upgrading the ERS on Great Ryrie Street Ringwood, at the entrance to Aquinas College and replacing the digital meter.
Work will start on Friday 26 June and be completed by Monday 13 July 2020, weather permitting.
Our contractor, Interflow, will be onsite from 7am to 5.30pm, Monday to Friday and Saturday from 9am to 1:00 pm.

Emergency Relief Structure Screens
To reduce the impact from sewer spills in extreme storm events, we are planning to install new screens at three Emergency Relief Structure sites. These are:
- Adjacent to 24 Harding Street, Coburg
- At the intersection of Rollo and Sussex streets, Pascoe Vale.
- Adjacent to 46 Hope Street, Brunswick.
The new screens will isolate, capture and store solids within the sewer and then, when flows recede, the solid waste is discharged back into the sewer.
This work will be completed by specialist contractors, Interflow, on behalf of Yarra Valley Water.
To enable access to the sewerage system to install the screens, a new maintenance hole will need to be constructed within local roads at each site.
While there will be detours and traffic management staff at each site, there will not be any restricted access to private driveways or disturbance to footpaths or nature strips.
This civil work will be completed Monday to Friday, from 7am to 5pm and Saturday 9am to 1pm.
Once installed, the screen will be tested and commissioned, and the construction area reinstated.
Work is scheduled to start at:
- Harding Street Coburg in mid-May 2020
- Rollo Street Pascoe Vale towards the end of May 2020
- Hope Street Brunswick in early June 2020.
Work at each site is expected to take up to three weeks to complete.
