Composting toilets and solar power systems are key components of off-grid living, and waste disposal is a crucial aspect of this lifestyle. In Arizona, composting toilets are legal but require a permit and specific regulations for wastewater disposal. Graywater recycling is also legal, with various financial incentives available for installing graywater systems. Solar power systems are legal in Arizona, but permits are required, with a quick process for small systems and more documentation needed for larger systems. Despite the many rules and regulations in Arizona, it is possible to live off-grid with careful planning and adherence to local zoning laws. With the right resources and mindset, off-grid living can be a fulfilling and sustainable way of life.
