Water by Design is commencing a project to collect, analyse and publish accurate updated WSUD maintenance cost data to support councils and asset owners across Australia.
Updated maintenance cost information is critically needed. The most recent data collection effort was completed in 2020 and costs are likely to have changed significantly since that time.
We are seeking data from both the public and private sectors nationwide to inform this project.
If you have data you are able to provide, please download the following documents and return to jack.m@hlw.org.au:
If you would like to know more or have questions about providing data, please contact jack.m@hlw.org.au.
Final data is sought by 27 March 2026.
