My catchment tank goes right up to the perimeter of my house (it is below the plane of the floor of the house). Another place I looked at (John will recall!) had the catchment tank (actually two) under the house. Both are nice arrangments aesthetically but the fire department likes you to have the catchment well away from the structures you want protected. With the house that had the catchment beneath it, that would certainly make it more challenging for the fire department to help you if there is no hydrant nearby.
