– Water and Wastewater Condition Assessment

The Water and Wastewater Condition Assessment Program is one of the projects being delivered through the Major Capital & Recovery Works Program of Douglas Shire Council (DSC) under contract CN2025-066. The project is supported by the Queensland Reconstruction Authority (QRA) Water Betterment funding.

Tropical Cyclone (TC) Jasper crossed the Queensland coast in the vicinity of Wujal Wujal in north Queensland on the evening of the 13th of December 2023. TC Jasper was associated with an extraordinary flooding event causing significant impacts to the region in north Queensland.

In the months following TC Jasper (16th of December 2023 to May 2025), pipeline failures increased noticeably against pre-event rates. It is considered that the cause of failure is in part, a result of the events that occurred during TC Jasper, including significant ground movement, prolonged saturation of the soil surrounding buried assets, and significant pressure fluctuation caused by repeated starting and stopping of the water supply, stressing pipe walls and joints. The traditional age-based renewal trigger previously used by DSC is likely to be inaccurate because it assumes typical operating conditions.

Therefore, the intent of the Water and Wastewater Condition Assessment Program is to undertake a complete condition assessment of DSC’s water supply and sewerage asset base so that renewal prioritisation moves from age-based triggers to measured condition, and so that post-TC Jasper renewal liability is quantified with field evidence rather than desktop estimation.
