Report as case 10004171.
It is now winter, and there is the Winter Sprinkler Ban, so don't know why the sprinklers are on.
The disappointing thing, it had been reported three weeks ago case 10003972 where it has been raining rather a lot.
It is currently being bounced around between Town of Vincent and Main Roads.
We're one of the driest states in WA, and really glad State and Local Government take these matters seriously.
