The main heart of the off-grid water management system is the water pump with diaphragm pressure tank. Please note this is very import, just buying and using a pump will not work in keeping the water pressure constant. You need a diaphragm pressure tank to work with it to keep the water pressure constant.
To make off-grid mobile living sustainable for short and long-term one needs to build a sustainable water and waste management system. Then one needs to determine how long do they need want off grid capacity before refueling and removing waste. There are many ways to extend off-grid living by changing the method of managing black and grey water waste disposal. On Angel Landings we are using eight 100 gallons black and grey water tanks, plus 12 water tanks. Using these many tanks one family of 6 can easily live off-grid for up to 2 weeks before refueling and cleaning. And for off-grid events such as golf tournament we can make this system work like a horse for a week without refueling or cleaning.
However, if one wanted to live there longer than 2 weeks maybe for a month then we would recommend using compositing toilet or portable septic tank, and reuse of grey water. One can even integrate rainwater collection for refilling the water tanks. One can easily extend the off grid living from 2 to 8 weeks.
To extend the use of off-grid water management system one can consider even further using an incinerator toilet, however they may not work on solar power-batteries and require shore connection.
In certain off-site locations water would need to be filtered and hard water filter maybe required. Since most of the main components are below the belly of the trailer frame it is easy for one to adjust the systems for their needs, such as adding water filters, clean out system, and additional capacity as needed.
Also, one can insulated the tanks from harsh cold/hot weather conditions. The black water tank can be enclosed in air-tight conditions to prevent any leaks or smell from the system that would affect the air flow into the natural cooling/heating mechanical system that sits under the belly of the trailer or crawl space.
