The Berejiklian government has delayed the expansion of Sydney’s desalination plant, just five months after it moved to double its size to provide more drinking water for the city.

As Sydney is no longer in drought and Warragamba Dam is at 83 per cent capacity, the government is reconsidering its water strategy for the city.

In January, Water Minister Melinda Pavey directed the operators of the plant, in Kurnell in Sydney’s south, to prepare for an expansion “as quickly as practicable”.
