It works real well. the water just goes out into the yard and never stands. No, it just comes from the driveway, for whatever reason there is a dip in the driveway , 2 ' from the garage door but it didn't run off on either side when there was grass there and if it rained real hard (like it has for a couple of months) it went into the garage. That palm is 3 or 4 times that size now
We have small barrels around the house and big tanks at the back of garage and outbuildings
