Dams have been vital in societal development since the first dam was made in Ancient Egypt. The first dam dates back to roughly 2950-2750 B.C and would have been made for the same reasons we continue to utilize dams today: water supply and electricity generation. It is for this latter reason that the Queensland Government has announced a $22 million Australian dollar investment into a new dam to be constructed in Borumba.
The detailed designs show a modern hydro-electric power producing dam. The plans for the design have been awarded to Powerlink, a publicly-owned electricity transmission company. The Queensland government has chosen Powerlink for their reputation in successful completion for other similar projects with such large infrastructures needed. Powerlink was also chosen for its links to and experience with the electricity market in Australia.
It is estimated the dam will create around 2000 jobs in construction, as well as positions for engineers, technicians and managers post-construction.
It is expected the business case will take up to 24 months and be submitted to the Queensland Government by the end of 2023. Post-construction the dam is aiming to serve roughly 1.5 million homes with hydroelectric power. This would make it the largest of the state’s pumped hydro stations. Premier for Queensland, Annastacia Palaszczuk, said: “More pumped hydro means more long-term, reliable energy and jobs for Queenslanders.”
Dams produce power by gathering a large body of water in a pool or lake like situation behind an artificially constructed wall, usually made of concrete. The natural flow of a river is disrupted by the building of the wall in segments. The river bed is then pumped also with concrete until the ground is totally hard and no water is allowed to escape. The trapped water behind the finished wall then builds up pressure which then turns wheels inside the concrete wall and generates power.
