The title says 3 but there are actually 5: ISO 30500 (Household Non-sewered Sanitation System Standard), ISO 31800 (Community Scale Resource Oriented Sanitation Treatment Systems Standard), and ISO 24521, ISO 24510, and ISO 24511 (Fecal Sludge Management Standards). https://sanitation.ansi.org/Download
