For this kind of application, I'm a big fan of this idea [1] (there is a more recent example of something similar out of the UK but I can't find it now). It uses a mechanical "flush" mechanism that basically just individually bags the waste and stashes it below the toilet. When full, the bags are pulled out (themselves in a bigger bag) and just taken to the dump. A great alternative to building custom sewer and treat…

Very interesting. I wonder if it then makes sense to run additional services such as power and drinking water parallel to those pipes for similar efficiency? I wonder if camping festivals and conferences such as CCC camp would benefit from this at all?

Original author here: yes of course, this project should be improved and many other additional services wil be added. I will also study a camp with UDDT to have a less amount of sewage. The camps in my project contain free areas for agriculture, in addition to a school , a police station, and markets so the camp could be 90% independent. This project could be applied for any camp. It is basically studied to be applie…

  This project could be applied for any camp
It's a pity this wasn't available for the Fyre Festival organisers. ;)

If I read the pipe maps correctly, it seems that the focus of the camp layout is on the sewage treatment facility, which is literally the center of the camp.

In my opinion, the center of the camp has prominence of place, and should be rather a social center of some kind: gathering place, daycare, school, workshops, communal kitchen, sports facilities, something like that.

A camp that elevate sewage treatment above all other concerns could be a grim place indeed. I imagine it should be possible to have an efficient, standardized sewage system that locates the physical plant off in a more discreet place

There seem to be ‘standards’ as to how to build out refugee camps and SOP for various things: * https://emergency.unhcr.org/entry/45581 * https://emergency.unhcr.org/about * https://spherestandards.org/handbook/ * https://en.wikipedia.org/wiki/Refugee_camp Even the humble tarp that meets these standards is more ‘advanced’ than it appears: * https://www.wired.com/2016/01/tarpaulin/

We used these camps standards to design the sewage system and of course to draw and design the standard camps.

For how the US Army does this, see Field Manual 3-34-471, "Plumbing, Pipe Fitting, and Sewerage", especially the sections on "Field Expedient Systems."[1] The Army has been building camps for a while. [1] https://www.constructionknowledge.net/public_domain_document...

Good information... But Our project is based on a sewage network for a standard camp.

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.

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).

> In the design, the slopes of the drainage pipes and the velocity constraints are selected in a way to have minimum excavation depths, and to have the flow velocity within its design ranges. I guess that the goal is to make it cost effective. To dig deeper that the strictly necessary would add durability that a temporary camp does not need and a lot of extra cost. It would have been nice to know the advantages and d…

Yes of course! It is found out that the circular design layout would be more economic than the hexagon design layout. Although, the circular design has less accommodation area than the latter one. On the other hand, if there is enough land to set up these camps, it would be better to choose the Hexagon design layout as it is more spacious and allow the use of more service facilities.
