Water Sensitive Urban Design Asset Inspections and Future Maintenance and Capital Works Planning


Bass Coast Shire Council


Phillip Island, Wonthaggi, Inverloch and surrounding towns, Victoria

Scope of Services:

Bass Coast Shire Council has 200 Water Sensitive Urban Design (WSUD) assets under their management.  This includes wetlands, sedimentation basins, rain gardens, vegetated swales and more.  Many of these assets have been constructed by developers and handed over to Council, particularly in the past 10 years.  Council engaged Engeny to provide expert input on how to best manage and maintain these assets.

The scope of the project was to:

  • Develop an assessment tool which was integrated into Council’s existing asset management system
  • Undertake an onsite assessment of each asset to determine how well the asset was currently functioning and to determine what remediation works would be needed to restore the asset to full function if it was not functioning as intended
  • Develop a long term renewal and maintenance program to bring all assets back up to a functional level

Following this project a detailed rehabilitation plan has been setup to bring the under performing assets back up to an appropriate standard and move them onto a regular maintenance regime to keep them performing at a high level. Council also have an improved understanding of the maintenance time and cost requirements of these assets which can be incorporated into future budget planning.
