Nice documentation of your use of standards and industry tools. In that way you're ready for professional practice.

Collection design appears appropriate, however an outfall location was not selected?

Collection system design is dependent on topography, do you have elevation data for proposed camp sites? Topography can inform your treatment site and outfall selection.

We have chosen the outfall to be in the middle of the circle and hexagonal sewage network. Yes of course, the topography should be first of all determined, this is what we did in the Zaatari camp design. We used Global Mapper to find the elevations, then we determined the outlet (lowest point).
