The New South Wales health department raised concerns Sydney’s drinking water could be harmed if the government goes ahead with its controversial Warragamba Dam wall-raising project, saying any impacts on quality would be “critical” for the delivery of “safe” water.

The previously unreported submission raised “concerns for drinking water quality” across Sydney during the construction of the raised dam wall, saying it would “limit the ability to avoid poor quality water in the dam”.
