No, I haven't really got an irrigation set up. 
Just my waste on a length of hose that reaches the front and back garden. 
Attached to a garden sprinkler. 
Then move the sprinkler about so it gets all of the grass.
I usually fill up at night so garden gets watered at night. 
Pack it away before I go to work.
It's all on a sub-meter. 
I just record the figures and send them off. 
Never had any issues so far (3 1/2 years at this house)
