From the air it looks like any other waste water treatment plant.
But this is actually the first hydro-electric power station in Australia to be powered by sewage.
The system is being pioneered in Sydney, Australia’s largest city.
It works by capturing the energy produced by treated waste water as it pours down a 60-metre shaft. The power generated will power up to 1,000 homes for one year. The process will also produce 40% of the sewage treatment plant’s own electricity. And the Sydney company’s greenhouse gas emissions will be reduced by more than 12,000 tonnes per year — the equivalent of taking 3,000 cars off the road.
The goal is to make Sydney Water’s energy and electricity operations “carbon neutral” by 2020.
