What is a septic tank system?

A septic tank system treats and retains sewage and sullage within the boundaries of your property.

The Environmental Protection Act requires that all systems generating less than 5,000 litres per day must be approved by Council prior to installation.

Applications must be made to Council for permission to install or alter septic tanks or other domestic wastewater treatment systems. 

Step 1

Contact Council to determine whether a planning permit is required. A septic tank permit cannot usually be approved until the planning permit is issued.

Step 2

Contact either your relevant water authority if applicable (Central Highlands Water, Barwon Water, Western Water, Goulburn Murray Water, or Southern Rural Water) to find out if further conditions apply.

Step 3

Submit the application form and pay any relevant fees. Along with the application form, you must also submit a site plan.

Step 4

Provide the plumber or builder your “Permit to Install”.

Land Capability Assessment (LCA) needs to be submitted as part of the application process. An LCA is a written report that assesses the various aspects of a site and determines the capability of the land to sustain a wastewater system.

You can contact a Land Capability Assessor but note that Council does not actively endorse any of the consultants listed.

Council will be assessing LCAs received using both the EPA Code of Practice and the recently released Victorian Land Capability Assessment Framework (VLCA) – 2nd Edition January 2014. 

Council’s Environmental Health Unit recommends you ensure your LCA meets the requirements of these documents and taking this approach to ensure consistency in the quality of LCAs received.

 

Approval Process

  • No installation work should be conducted without the “Permit to Install”. 24 hours before works begin the owner or the plumber should contact Council’s Environmental Health Unit to request a progress inspection
  • Once Council’s Environmental Health Unit receives and approves this document, you will be issued with a “Permit to Use” the septic tank system
  • Note: A Building Surveyor cannot issue an “occupancy certificate” until Council issues your “Permit to Use”

 

Maintaining your System

  • The property owner is responsible for maintaining the septic tank system
  • All septic tanks including a standard septic tank and an aerated wastewater treatment system (AWTS) must be desludged at least once every 3 years
  • An AWTS must be serviced through a contract with an accredited service technician every 3 months

A list of service providers is available and an example of a service report is provided that shows all the areas that need attention during a service. 

 

Failure to maintain System

Council follows up all owners or occupiers that are not maintaining their systems within the required timeframe.

Failure to maintain your system is an offence under Section 53N of the Environmental Protection Act 1970 and can result in an infringement of 5 penalty units.

Domestic Wastewater Management Plan

Council's Domestic Wastewater Management Plan (DWMP) allows for better development of houses in regional areas where waterways may otherwise have excessively restricted growth.

Moorabool Shire Council  Audit report (December 2017) presents the findings resulting from the audit of the DWMP.

 

 

Frequently Asked Questions

  • I would like an additional copy of my (or a client's) permit to Install, Alter or Use a septic system; or documents regarding my septic, how do I go about it?

    Any additional septic permit or any documentation Council has about your septic can be provided by Council by lodging a written request via email to info@moorabool.vic.gov.au or via post/ in person with a Septic/ Sewer information request which carries a fee of $59.00.

  • I don't want to install the type of system I have been allowed, why am I limited in my choices?

    Depending on your block size and its proximity to various water ways a septic system can pose a greater risk to the local environment and drinking water: due to this Council and water authorities may insist on particular types of systems which treat your waste to a higher standard.

  • I want to build an addition to my home; do I need to change my waste-water treatment system?

    If your addition is likely to increase the potential number of bedrooms or is not functioning correctly Council is obligated to ensure that the wastewater treatment system meets potential needs.  You will need to apply for a permit to alter your septic system (PDF, 212.73 KB) in this case.
