A neat project we have finished up is a custom water tower/shower for camping. A simple design using an IBC tote which are exceedingly ubiquitous perched ontop of a ~2m tower. It heats up fairly well from the sunlight but intention is to paint it black to help. The base doubles as a shower pulling directly from the water above and there is a distribution block that goes into a utility sink and to the camper.
Water pressure is not great but more than sufficient for outdoor needs. To refill the tank we have a 2nd IBC tote that we drive to a nearby steam fill up with a sump pump and then transfer into the raised IBC tote. It has been a very successful project that has provided a stable water supply to our campground.
