Water and Wastewater Condition Assessment

Overview Douglas Shire Council (DSC) is seeking a suitably qualified provider to deliver the Water and Wastewater Condition Assessment Program under contract CN2025-066. This project forms part of DSC's Major Capital & Recovery Works Program and is supported by Queensland Reconstruction Authority (QRA) Water Betterment funding. About Tropical Cyclone (TC) Jasper crossed the Queensland coast in the vicinity of Wujal Wujal in north Queensland on the evening of 13 December 2023. TC Jasper was associated with an extraordinary flooding event that caused significant impacts across the region. In the months following TC Jasper (16 December 2023 to May 2025), pipeline failures increased noticeably against pre-event rates. This is considered to be, 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, which stressed 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. Purpose 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. Scope Complete condition assessment of DSC's water supply and sewerage asset base Tender Briefing and Site Inspection This tender requires a mandatory site visit. Date: Thursday, 19 November 2026 Time: 9:00 am Location: DSC Works Depot, Mossman Attendance: Limited to two representatives per tenderer Names and contact details of attending representatives are to be communicated through the tendering portal.
