Australian utility expands groundwater replenishment scheme
Water Corporation, an Australian utility, has expanded its groundwater replenishment scheme to double its recharge capacity, securing the potable water supply in the Perth region.
Due to the impacts of climate change, the utility decided to expand the project to increase its water source, which was climate dependent. The process involves treating wastewater to potable standards, followed by injecting it to top up groundwater supplies, into natural aquifers. This can then be used when needed without reliance on rainfall. The scheme currently makes up 3% of Water Corporation’s supply scheme, and the expansion expects to double the recharge capacity.
