At our old house, we put one at the interface between our semicircle drive and the short walk to our front porch, it was connected to black corrugated piping routed on the downhill side around the house and terminated in the side yard at a square drain box that acted like a bubbler to disperse the water where it could easily drain. Worked pretty well to deal with summer inundations, the area in question would drain naturally just not as quickly as I wanted.
