Mansfield Shire Council is inviting the community to provide feedback on the existing adopted On‑site Wastewater Management Plan (OWMP) 2022.
The OWMP sets out how Council manages existing and future on‑site wastewater systems (such as septic systems) across the Shire—particularly in areas without reticulated sewerage and within declared potable water supply catchments.
This is the first round of community engagement, and your feedback will help shape the updated Plan before it is refined and presented to Council.
Why the OWMP Matters
Around 95% of Mansfield Shire lies within a declared potable water supply catchment. How wastewater is treated and managed on private land plays a critical role in protecting:
drinking water quality
public health
local waterways and Lake Eildon
community amenity and environmental values
The OWMP takes a risk‑based approach, focusing effort where the potential impacts are greatest and reducing unnecessary regulation in lower‑risk areas.
About the Draft OWMP
The draft OWMP builds on Council’s earlier Domestic Wastewater Management Plan (2014) revised and adopted in 2022 and reflects:
updated state legislation, including the Environment Protection Act 2017 and General Environmental Duty
current EPA Codes of Practice
improved data, mapping and risk analysis
collaboration with key agencies such as Goulburn Murray Water, Goulburn Valley Water, and environmental health specialists
The Plan identifies high, medium and low‑risk catchments and sub‑catchments and sets out:
expectations for new development
requirements for land capability assessments
how Council will monitor and manage existing systems
priorities for education, compliance and infrastructure planning
Please review the current OWMP and provide feedback to help improve clarity, practicality and community understanding.
Feedback closes Monday 18 May 2026.

Council is reviewing the On-site Wastewater Management Plan (OWMP) to better manage risks to the public health and the environment from septic systems and wastewater in unsewered areas.
We'd like your feedback to help inform the updated plan.
