We’re planning for the future of onsite wastewater management in Cardinia and we’d love your thoughts!

The draft Onsite Wastewater Management Plan has been shaped by ideas and concerns shared during our first round of community consultation earlier this year. This plan looks at how we can manage onsite wastewater systems safely and sustainably, protecting both our health and the environment.

What’s in the draft plan?

• Better ways to assess risks with onsite wastewater systems
• Stronger strategies to prevent wastewater leaving your property
• Clear steps and timelines for fixing non-compliance issues

Now it’s your turn to have a say! Your feedback will help us make sure the final plan works for our community and supports a healthy environment for years to come.

Check out the draft plan below and share your thoughts before consultation closes on 18 December 2025.

We're working on a new Onsite Wastewater Management plan that helps protect our health and environment by ensuring wastewater management systems, commonly known as septic tanks are correctly installed, managed and maintained.

What the Plan Will Do

• Assesses the risks to human health and the environment posed by onsite wastewater systems (commonly known as septic tanks). This includes the risk to groundwater and surface water from existing and future systems, and the risk of existing systems that are, or could be discharging beyond the property boundaries
• Identifies actions and timeframes to improve the management of these systems and minimise the risks. 
• Manages non-compliance and what their enforcement approach is. 

Why We Need Your Input

To enhance the approach to onsite wastewater management, Council is seeking community feedback to understand residents' experiences and priorities regarding wastewater management.

Do you have a septic system or live near one? Have you noticed any issues with wastewater on your property or in your neighbourhood? Do you care about protecting our water, land, and community health? We want to hear from you!
