Effluent Management

The sewer system within the townsites of Eaton, Millbridge, Dardanup and Burekup is owned and operated by the Water Corporation. To find out if your property has sewer available conduct a search of the Water Corporation’s property rating system here

Information and plumbing diagrams for properties connected to sewer, is held by the Department of Mines, Industry Regulation and Safety and a search can be conducted here

Where sewer is not available, onsite effluent disposal can be considered. An onsite effluent disposal or septic approval is one of the “prescribed” approves required before a Building Permit can be issued for a project.

The Shire of Dardanup is only able to consider disposal systems that have first been approved for use in Western Australia by the State Department of Health. The Shire is also required to consider the Department’s approval conditions to ensure that the installation can achieve the approval requirements on the site proposed.

There are some subdivisions within the Shire that, due to the site conditions such as high ground water, poor drainage and proximity to sensitive water sources, require secondary treatment systems as a condition of the subdivision. The Shire is limited to considering only those systems nominated in the subdivision approval for those relevant sites.

Types of onsite effluent disposal systems include:

• Secondary Treatment and Aerated Wastewater Treatment Systems
• Alternative Treatment Systems
• Alternative Toilets
• Greywater Systems
• Leach Drains
• Septic Tanks

Please note that Alternative Toilets are not supported in residential zoned areas of the Shire of Dardanup and may not be suitable on small rural landholdings.

It is always best to speak with your licensed plumber about your preferred system so that they may offer you some practical advice regarding installations and maintenance.

All applications are required to be submitted on the prescribed form available here.

For commercial installations, additional information is required, with all applications required to be referred by the Shire to the State Health Department. This process and the relevant application considerations are summarised here.
