ᐅ Roof drainage, downspouts below sewer level for a house on a slope

bortelHello everyone,
Gradually, we are gaining more insights regarding the plot we purchased on a hillside. We are planning a typical gable roof house on the slope, oriented north/south. The street is located to the north. It has now become clear that the stormwater outlet is positioned at a higher elevation, so the downpipes will have to discharge on the south side. Unfortunately, due to the eaves height regulations in the building area, it is very difficult to rotate the roof to an east/west orientation, since this would require maintaining an eaves height of 3 meters (10 feet). With the north/south orientation, we have 6 meters (20 feet) and 3 meters (10 feet) respectively facing the street.
Now to my main concern/problem. At the moment, we don’t have a viable idea for draining the south roof. A rainwater tank combined with an infiltration trench is not permitted, as the soil report states that no water can be infiltrated into the ground.
What do you think about routing the two downpipes (east/west, since a dormer is planned on the south side due to the eaves height) along the exterior wall and cladding the house with HPL laminate/Trespa panels to conceal the pipes? Are there other ideas on how this issue might be resolved? We would prefer not to use a pump to raise the rainwater, as we have been advised against this from all sides.
I am grateful for any advice!
