Biological water treatment systems in Perth could be among the different solutions for its current supply problems, as the city consumed more water than expected between July and October.
The city’s residents connected to Western Australia’s public water supply consumed almost 71 billion litres of water from July 1 to Oct. 22. The rate of consumption exceeded Water Corporation’s forecast by around five billion litres.
The recent figures indicate a need to find alternative sources and conserve available supply at the same time. Officials have already advised households to limit their use, especially since the statistics also showed an upward trend.
Residents under the state’s water supply scheme consumed 67.9 billion litres between July 1 and Oct. 22, 2016. In the past four years, the state has fallen behind its target consumption, but the government doesn’t intend on enforcing stricter rules for now.
On the contrary, many believe that finding new sources such as a desalination facility should be a priority instead of new regulations.
A survey showed that nearly 50 per cent of Western Australians support a new desalination plant, which will be an additional drinking water source for Perth. The respondents chose desalinated ocean water as their top choice for improving supply.
Other potential sources include recycled wastewater and water treatment, which are already available from different companies. Some also said that further reducing their use is no longer possible, and this means that the current restrictions may have reached their limit.
In terms of non-potable water, the survey listed recycling grey water and harvesting rain as some of the top choices.
Western Australia needs more than just regulatory policies in maintaining a reliable supply of water. While it’s good to conserve water, population growth would require a bigger solution that focuses on finding new sources to meet growing demand.
