At least. Their policy is pretty clearly stated :
"Proper irrigation design provides for Head to Head coverage. By
spacing the sprinkler heads so that the spray from one head reaches adjacent
heads, water is applied evenly."
Looking at the sample diagram, they have some areas watered by as many as 4
separate heads !
