Queensland Hydro has announced the successful tenderers for three major works packages for the Borumba Pumped Hydro project.
Borumba Pumped Hydro is a major, 2000 megawatt renewable energy project at Lake Borumba, located near Imbil, west of the Sunshine Coast.
The existing lower reservoir (Lake Borumba) will be expanded with a new dam wall downstream from the current Borumba Dam. A second reservoir will be constructed at a higher altitude. An underground powerhouse will link the two reservoirs together. When electricity is required, water will be released from the upper reservoir through underground turbines via tunnels to the lower reservoir.
Water2Wire Joint Venture (JV) have been appointed as Dams Designer Delivery Partner, with packages totalling $40 million awarded to advance the design and engineering of both the upper and lower reservoirs.
Water2Wire JV will be responsible for leading the engineering and design for the Borumba Project’s seven proposed dams which involve six new dams to form a new upper reservoir, and one new dam wall and spillway immediately downstream from the existing Borumba Dam.

The replacement dam wall will see Lake Borumba increase its capacity providing security to the proposed energy storage scheme.
AFRY-Aurecon JV were awarded the $39.9 million Pumped Hydro Energy Storage (PHES) Designer package. The package will see AFRY-Aurecon advance the front-end engineering design documentation, focusing on the technical elements of the pumped hydro scheme itself – such as the interplay between the turbines, cavern design, tunnel waterway design, and other equipment.
Decmil have been awarded a contract totalling approximately $111M to design and construct two temporary worker camps on the site of the Borumba Project.
The best practice camps will be able to house up to 336 workers each, with each location containing a wellness room, gym facility, running track, social room, laundry facilities making workers on one of Queensland’s most important infrastructure projects feel right at home.
Initial construction will see two camps built on-site to accommodate the immediate needs of the workforce before the two temporary workers’ accommodation camps will be constructed at the same locations to accommodate workers on the Borumba Project.
