Drainage is where the water will go and how it goes there. In the majority of situations, rain waterfalls from the eves of the house or building directly onto the bottom. This is fine if the ground around the structure slopes off from the building. This could keep water away from the base.
After that, the water tends to run to the bottom point it may. In a typical suburban setting, it's going to run to the front windshield, because city principals insist on a house is greater than the street, and all the concrete horizontal work sloping to and connecting with the city street gutter.

After the water enters the road gutter it simply runs away, because of the slope of the gutter. What exactly we're worried about is getting that rainwater from the roof into the road gutter without inducing annoyance or damage on the way.
Most homes have rainwater gutters that station water into certain areas and deliver the water spouts to the bottom. This enables us to only have to deal with some special spots around the home or construction that'll have a large amount of water that should be managed.
For the best results, a subsurface drains system will be installed and attached directly to the down to capture the rainwater and then take it into the designated location for absorption.
