You should see if you can reach out to the Chaos Computer Club for their Camp conference (in theory, running next in 2023).
The distribution of utilities throughout their campsite is quite a logistical challenge.
I think your work also assumes a nice flat wide open space that you can work with, whereas in that specific scenario there's other obstacles in the way.
CCC Camp infrastructure is special, and fun, and definitely a great source of real-world experience. The various infra teams now have a decades of experience scaling it up - water, power, waste, internet, each coming with its own set of challenges. The event is full of engineers, such that the level of overengineering increases year by year - last camp, one team even brought and manned industrial dishwashers as a public service! Same goes for similar non-profit events that build their own infra rather than contracting it out to an expensive events company.
Constraints are very different, obviously - the ground can't be dug up, public toilets and washing stations are sufficient, there's some existing infrastructure to partially rely on, and it only has to work for at most ~2 weeks or so. Still, many of the "lessons learned" could be applicable elsewhere and I wish there was time to document more of it.
Anyway, really cool. Thanks! :)
