The Toowoomba Pipeline was delivered by the Toowoomba Pipeline Alliance (TPA) for LinkWater Projects, one of the state government's special purpose vehicles for the design and construction of water infrastructure.

The pipeline links Wivenhoe Dam to Toowoomba's Cressbrook Dam, with an initial capacity to transport up to 14,200 megalitres a year and ultimately, up to 18,000 megalitres a year. In its first year, it will deliver 10,000 megalitres to Toowoomba. 

The TPA team was assembled in 2008 with the first pipe laid in March 2009.

TPA partners were LinkWater Projects, Clough, WDS and AECOM.
