  • Although there were significant time constraints for delivery, whilst still in the early planning phase opportunities to undertaken works in parallel are being investigated to minimise activities in later stages. e.g. undertake non-sacrificial work in the early planning phase that is required in future phases of delivery.
  • Early stakeholder engagement was undertaken to facilitate with the relevant approvals.
  • Identification of a delivery model which would facilitate the time constraints on the project and manage the risk profile for Council.


Toowoomba Regional Council’s Cressbrook Dam is required to be upgraded to meet the requirements of the Guidelines of Acceptable Flood Capacity (AFC) for Dams (ANCOLD 2000). The aim of the improvement program is to improve the dam’s ability to withstand extreme events. The project includes the planning, procurement and delivery of the works, which is expected to enter construction phase in 2024 with an anticipated completion date of late 2025. 


Toowoomba Regional Council (TRC) is carrying out a project to improve dam safety at Cressbrook Dam. The safety upgrades will meet the Dam Safety Condition Schedule issued by the Department of Regional Development, Manufacturing and Water (DRDMW). Which requires Council, as the owner of the dams, undertake appropriate works to meet the requirements of the Guidelines of Acceptable Flood Capacity (AFC) for Dams (ANCOLD 2000). Council is required to undertake and complete the minimum safety upgrade works by October 2025.

The project will improve the long-term viability of the dam assets so that they can continue to: 

  • Safely pass excess volumes of water during periods of extreme rainfall.
  • Meet modern engineering design standards
  • Improve community safety and water supply security
  • Comply with the safety requirements set out in the Water Supply (Safety and Reliability) Act 2008 (Qld).  

The project aims to deliver the upgrades without impacting the security of the drinking water supply.
