Olinda Sewerage Project
Once complete, the project will provide sewerage services to approximately 500 properties in Olinda and parts of Mount Dandenong that can’t contain their wastewater on-site.
We'll construct the new sewerage pipelines progressively from south to north. Every property along the sewerage pipe path will receive a connection point.
All properties will be serviced using a pressure sewer system. For information about pressure sewer systems, visit our Frequently Asked Questions page.
This project will benefit the community by:
• Improving the health of local waterways.
• Protecting public health.
• Reducing sewer odours that are currently noticeable in the area, providing a more liveable environment for locals and visitors to the area.

What should you do right now?
You don't need to do anything right now, except keep maintaining your current onsite wastewater (septic) system.
We'll be in touch with property owners directly as we progress.

Project updates
August 2024 – trader consultation session – Monday 2 September, 9 am
As we finalise the design and start moving towards construction of the new sewerage system, we'd like to invite local traders to attend our engagement session.
We're conscious Olinda retailers are dependent on visitors and tourists to the area, so we'd like to provide you with information about how we’ll manage the sewerage project. We’d also like you to share your perspectives, ideas and concerns.
WHAT: Information and consultation about the upcoming sewerage project
DATE: Monday 2 September 2024
TIME: 9 - 10 am
WHERE: Olinda Community House, 79-81 Olinda Monbulk Road (next to Olinda swimming pool)
March 2023 - information session - webinar recording
Our recent information sessions were well attended and generated some great questions. If you were unable to attend and are interested to learn more about the Community Sewerage Program and what it means for you in Olinda, you can catch up with a video recording of a webinar session here:

What's happening in Olinda?
We're conducting investigation works for this project which will allow us to refine our engineering designs for the sewerage system.
Will I be receiving a sewerage service?
The design process determines the feasibility of where we can install pipes and takes into account many factors including topography, ecological impact, distance to existing infrastructure and hydraulics.
In the coming months, we’ll be in touch directly with property owners who will be receiving a sewerage service with more information.
What investigation works are taking place?
Between now and the mid-2023, our specialist contractors will be be surveying and investigating local conditions, including:
- Geotechnical sampling – small bore holes are drilled in different areas and soil and rock samples are analysed to help determine the best location for the sewerage pipes.
- Cultural heritage investigation – to assess the potential impact of a proposed activity on Aboriginal cultural heritage. These investigations are part of a Cultural Heritage Management Plan required under the Aboriginal Heritage Act 2006 and involve digging small holes in different parts of the project area. The results will be available before the end of the year.
- Ecological surveying – required to help inform the route of our pipelines, reduce the need to disturb vegetation and to protect the environment.
- Service proving – using ‘non-destructive digging’ to verify infrastructure locations. The ‘digging’ involves using high pressure water to dislodge soil in road reserves and pathways. Using this equipment minimises the risk of causing damage to existing pipes and infrastructure, as well as tree roots and vegetation.
Why does this area need a piped sewerage system?
Septic tanks work by gradually releasing wastewater so that it's absorbed by the soil and plants on your property. If they're old and beyond their service life, fail or aren’t maintained properly, they can create unpleasant smells and boggy areas. They can leak waste onto other properties, or the wastewater can flow into local drains and waterways. Sometimes properties are too small to contain the waste, or the land might be steep, so the waste runs off before it is absorbed.
Also, many properties have split systems where toilet water is treated by the septic tank and the wastewater from the kitchen, shower and laundry flows into the stormwater system. This waste is not treated and flows into our creeks, rivers and bay, polluting our waterways.
