Works in your area starting in August 2023

We’re continuously receiving feedback from our neighbours and the local community on odour coming from our pump station in Sixth Avenue, Rosebud. Over the last few years we updated some of the station’s parts to improve the odour issues. We're now planning to further upgrade the pump station.

What we're doing

After receiving feedback from our neighbours and the local community on odour coming from our pump station and updating some of the station's parts to improve odour issues, we’re now planning to further upgrade the pump station.

This includes the replacement of the existing 9 metre tall ventilation with a new 15 metre tall ventilation stack to further improve the odour in the area. This upgrade will also extend the life of the station and sewer network and mitigate corrosion.

You shouldn't notice any change to your water or sewer services while we work.

When it's happening

We’ve been delayed and are still in the planning stages of this project. We’re aiming to start works from 21 August 2023 with the installation of the new ventilation stack happening from early September 2023The entire upgrade should take around 10 weeks to complete, depending on the weather. We've installed the new stack but you might still see us around until the end of January 2024 as we finalise works. We apologise for the delay.

You can expect us to work Monday to Friday between 7am and 6pm. On the odd occasion, we might need to work at other times for safety, technical or permit reasons.

You may notice an increase in odour for a short period during the project where we’ll need to temporarily shut down some machines at the pump station to undertake part the upgrade.


What might impact you

We’ll do our best to keep impacts to a minimum. However these are the kinds of things you might notice while we work:

  • More trucks on the streets around you.
  • Noise from machinery, like beepers when trucks reverse.

Once construction is complete, you will be able to see the new vent stack from the street (you can find out more from the Fact Sheet below). 

Don't miss these details

We're working with our delivery partner Emission Treatment Solutions to help us with this project.

A ventilation stack is an above ground pipe that safely diffuses and dilutes treated gases from our underground sewer network into the air. There are 100s across our service area which help our network work around the clock in taking waste away.

The new ventilation stack we’re planning for your area does look different to what’s there at the moment. We’ve included a fact sheet to show you our design concept. 

We're also planning a future major upgrade in and around the pump station to cater for growth in the area. We're still finalising the details and we'll let you know when we have more information.

Frequently Asked Questions

Ventilation stacks across our service area play an important role in taking waste away safely. We're upgrading the ventilation stack at Sixth Avenue, Rosebud to further improve odour issues and prolong the life of our sewerage network.

A ventilation stack is an above ground pipe that safely diffuses and dilutes treated gases from our underground sewer network high into the air.

A ventilation stack looks similar to a metal pipe with an opening at the top. Its height, diameter and appearance depend on the required ventilation and the area's wind pattern.

Sewage decomposes over time generating odorous gases. If these gases stay inside our sewer network they prematurely degrade the sewage infrastructure including the pump station at Sixth Ave, Rosebud that services your community. The amount of gas depends on your community’s sewage discharge which changes over time. To keep sewage infrastructure working safely and efficiently we pretreat these gases to reduce their odour.

The ventilation stack removes odour from our pump station by venting high above into the air to further dilute odours. This means you cannot smell the gases at ground levels and nearby properties, including two-storey buildings. We use best practice technology to treat the air prior to releasing it out of the ventilation stack.

As part of our ongoing asset monitoring and improvement program we've found the existing 9m tall ventilation stack is no longer suitable to service your community. We came to this decision following the Environmental Protection Authority (EPA) approved modelling methods. 

We now need to upgrade the 9m stack to an 18m tall ventilation stack to meet EPA odour requirements. The new ventilation stack will have wind stabilising spirals at the top. We'll powder coat it with Dulux Anotec Silver Grey Matt or equivalent, so it blends in with the background as much as possible given varying weather conditions and time of the day. Please refer to our concept photos in the Fact Sheet below.


There will be no increase in noise from the ventilation stack upon completion of the upgrade. In most cases, ventilation stacks don't make any noise. The upgraded ventilation stack is designed to meet EPA noise level limits.

As part of the works, we'll also upgrade noise mitigation measures at the pump station in accordance with EPA guidelines.

The ventilation stack location won't change and remain located within the boundary of the Sixth Avenue Pump Station.

We're not anticipating any unpleasant smells will be noticeable from the ventilation stack. The purpose of a ventilation stack is to remove and disperse sewer gases high into the air to mitigate odour and corrosion. 

During operations and maintenance activities at the pump station, there may be intermittent odours as we keep the doors open to maintain a safe means of access for our workers. This takes one day around every 3 months.

Construction hours
Regular construction hours are between 7am and 6pm, Monday to Friday (weather permitting). Work may occasionally be required outside of these hours. We'll let you know of any work required outside our regular construction hours.

Under the Water Act 1989, we're required to undertake these works in our licenced area to ensure safe, reliable and efficient operation of our network for all customers. We also operate under the Water Estimation, Supply and Sewerage Regulations 2014.

We must comply with regulations from the EPA, the Department of Health and other government agencies. This ensures all of our assets and infrastructure meet legal and statutory requirements regarding public safety and to ensure the health and wellbeing of operators and maintenance staff.
