A SUBURBAN Perth street is in lockdown after a water main burst this morning spewing rocks, mud and thousands of litres of water into the air.
A river of water can be seen running down Clayton Road and a nearby house outside the Boya Community Hub.
The Department of Fire and Emergency Services, Shire of Mundaring staff and the Water Corporation are at the scene.
Police have blocked off all roads at the Scott Street roundabout in Boya.
Motorists are advised to avoid the area.
