Toowoomba to Warwick Pipeline

The Toowoomba to Warwick Pipeline is a proposed expansion to water services in Queensland's south-west, connecting water reservoirs between Toowoomba and Warwick. The scope of the project includes:

  • a connection to Perseverance Pipeline up to the downstream flange of the control valve prior to the Mt Kynoch Water Treatment Plant
  • two three-megalitre reservoirs at Highfields
  • a 113 kilometre underground pipeline from the connection point with Perseverance Pipeline (west of Toowoomba) to the Warwick Reservoir
  • off-takes at the rural TRC towns of Cambooya, Greenmount, Nobby, Clifton
  • an intermediate pump station and a 100 kilolitre Balance Tank
  • Allora borefield supply connection into the pipeline
  • a 15-megalitre reservoir at Warwick.

The proposed T2W pipeline route starts west of Toowoomba where it will connect to the Perseverance Pipeline, and wil run south near Wyreema, Cambooya, Greenmount, Nobby, Kings Creek, Clifton, Elphinstone, Allora, Hendon, Deuchar, Massie and Toolburra. The route will finish west of Warwick at the new 15 megalitre Warwick Reservoir. 

The Pipeline will be constructed, owned, and operated by Seqwater.
