What Yarra Ranges asks for
Yarra Ranges has roughly 22,000 on-site wastewater systems — the second-largest count of any Victorian council — spread across steep, treed hills country in Melbourne's drinking-water catchments. That shapes how the council assesses applications: slope, landslip risk, tree protection zones, soil type, lot size and distance to waterways all get weighed, and the firm rule for new systems is that all wastewater must be treated and contained within the property boundary. The process and forms are set out on Yarra Ranges Council's septic systems page, with applications lodged through the council's online portal or on the PDF forms.
Fees for 2025–26 are $750 for a new installation or major alteration and $580 for a minor alteration. Otherwise the shire follows the standard Victorian pathway under the Environment Protection Act 2017: a land capability assessment to size the land application area, a system with a current certificate of conformity, council inspection during installation, and a permit to use before the system is switched on.
- Application form plus a site plan showing the tank, land application area and setbacks to boundaries, buildings and waterways
- Land capability assessment — expect one on the shire's many small, steep or constrained hills lots
- Extensions, extra bedrooms or a commercial change that adds wastewater load trigger a council review of whether the existing system copes
- Many pre-1990s systems legally discharge to easements or roadside drains — upgrades to full on-site containment are a council priority, so budget for that if you're altering an old system

Common questions
Do I need a land capability assessment in Yarra Ranges?
For a new system, plan on it. Much of the shire is steep, small-lot or close to waterways — exactly the constraints an LCA exists to resolve — and council assesses every application against them. Our LCA cost guide covers what the report costs and includes.
My old septic drains to the roadside drain. Do I have to upgrade?
Not automatically, but the council is actively working to phase out legacy off-site discharge, and any alteration, extension or added bedroom is the usual trigger for requiring an upgrade to a system that contains everything on the property. If yours is struggling, start with the warning signs guide.
How much is a septic permit in Yarra Ranges?
$750 for a new installation or major alteration and $580 for a minor alteration in 2025–26, on top of your LCA and installation costs. See the full system cost guide for the total picture.
