A burst pipe has disrupted water supply to more than 20,000 properties in Sydney’s North Shore and sent murky water seeping into the harbour.

Sydney Water is working to repair a burst main that ruptured Grasmere Road in Cremorne near Primrose Park.

Thousands of residents across Cremorne, Mosman, North Sydney, Crows Nest, Artarmon, Chatswood, Roseville and Lindfield have reported receiving little to no water this morning.

“Crews are working to isolate the main and restore pressure and supply to surrounding suburbs and customers in the area,” a Sydney Water spokesperson said. 

“Motorists are advised to avoid the intersection of Grasmere Road and Young Street, Cremorne, so this critical work can be carried out safely.” 

The burst main has caused flooding in residential areas.

It appears to have led to the bottom of Primrose Park and seeped into the Sydney Harbour.

“Sydney Water apologises for the inconvenience and appreciates the community’s patience while we work to restore normal operations,” the spokesperson said.
