Drainage plumbing diagrams (also known as flimsies or as constructed diagrams) are a diagrammatic representation of a property’s drainage plumbing work.
Drainage plumbing diagrams are regularly used by homeowners, licensed plumbing contractors and others to determine the layout of drainage plumbing on a property. Knowing the layout of drainage plumbing can assist in:
- Identifying where additional connections to existing drainage plumbing may be made;
- ensuring that new buildings or extensions do not interfere with existing drainage plumbing;
- ensuring that any excavation works do not disturb the drainage plumbing;
- the repair of drainage pipework; and
- clearing blocked drains.
Requesting drainage plumbing diagrams
Drainage plumbing diagrams are available from the ‘Search for Drainage Plumbing Diagrams’ web page.
If anyone has any issues with internet access, they may contact Building and Energy on 1300 489 099 for assistance in accessing drainage plumbing diagrams.
In order to test the drainage plumbing diagram service, Building and Energy will be providing drainage plumbing diagrams free of charge initially. Once the service is fully operational, drainage plumbing diagrams will only be available on payment of a fee.
Where the property is not connected to main sewerage
Up until 14 December 2016, it was not a requirement for licensed plumbing contractors to submit drainage plumbing diagrams to any sewerage service provider for any drainage plumbing work that occurred on a property not connected to main sewerage (e.g. where the property is connected to a septic tank or aerobic treatment unit).
In this scenario, the relevant local government authority is best placed to provide you with information on the possible existence of a drainage plumbing diagram for that property.
Where the property is connected to a main sewer operated by a sewerage service provider other than the Water Corporation
Building and Energy has only obtained historical drainage plumbing diagrams from the Water Corporation. In areas serviced by other sewerage service providers, such as the City of Kalgoorlie-Boulder, any drainage plumbing diagrams relating to work completed prior to 14 December 2016 remains the ownership of the relevant sewerage service provider who should be contacted for further assistance. Information about sewerage service providers is available at www.erawa.com.au/water1/water-licensing/licence-holders.
Dormant lines (Z files)
Dormant lines are internal sewer lines servicing multiple properties at the same address, e.g. an additional house as part of a sub-division or a group of townhouses. Diagrams for dormant lines have historically been referred to as Z files. Diagrams of internal sewer lines prior to 14 December 2016 are not available on the DPD online search. Building and Energy can investigate whether a diagram exists however. Please contact (08) 6251 1301 or firstname.lastname@example.org to make a request. A $10.50 purchase fee also applies to internal sewer line diagrams.
Issues with drainage plumbing diagrams and purchase fee refunds
As we are dealing with historical records, there may be occasions where drainage plumbing diagrams are not suited for the purpose of determining the layout of drainage plumbing at a property. Some issues that may occur include the property address being recorded incorrectly, insufficient detail being included on the drainage plumbing diagram or the diagram being poorly scanned. If you identify any issues, please email Building and Energy at email@example.com and include a brief comment on the issues identified as well as your contact details, or phone on 6251 1301.
A refund of the purchase fee may be provided in certain circumstances.
Submitting drainage plumbing diagrams
Licensed plumbing contractors are required to submit a drainage plumbing diagram when they are the responsible person for drainage plumbing work that involves the installation, alteration or extension of drainage plumbing.
The drainage plumbing diagram should be submitted with the related certificate of compliance, which is required to be provided to the Plumbers Licensing Board (the Board) within 5 working days after the day on which the work is completed.
Further information on submitting drainage plumbing diagrams, including what should be included on the drawing, is available in the Drainage plumbing diagrams: Submissions and requests guidelines.
