25/2/25: Toowoomba Bore (Queensland)
PFAS detection (0.094µg/L) at a Toowoomba bore site. Preventative Action: DWI-499-25-11998 Isolated bore from service
The main water sources for the Toowoomba scheme are:
- Dams: Cressbrook, Cooby and Perseverance.
- Bores: 47 bore stations. Bores access groundwater and contribute approximately 20-30% of our water supply.
- Wivenhoe Dam pipeline: The pipeline from Wivenhoe Dam (SEQWater) provides security of supply when the rainfall in our dam catchments is insufficient to maintain supply to meet the region’s growing needs. Once the capacity of Cressbrook dam falls below 40% we can start using water from Wivenhoe Dam.
