Water supplies to the west of Balmoral Road may be affected.

“Shoalhaven Water is temporarily diverting mains water around the affected area and customers may experience less than normal water pressure,” said a Shoalhaven Water statement.

“The break has occured in a difficult to reach location and it is not expected that repairs will be completed until Tuesday afternoon (March 21).

“A further update will be provided once the main has been excavated and more is known.”
