Intelligent comment, the layout 2 has the problem that you are talking about as the sewage is located in the center of the camp, but the layout 1 has a better design as it is half a circle and the sewage could be treated away from the tents accommodation and other activities.

Yes... except that with the semi circular layout, the sewage treatment is still in the only prominent place in the camp. All roads lead to the plant. If the city were an auditorium, the plant is squarely on stage. That should still be the place where people gather socially
