Sanitation - Nonsewered Waste Disposal Systems: Use by the General Public - Minimum Requirements
This standard applies to portable nonsewered waste disposal systems for use by the general public at all locations, wherever such systems are not connected to a sanitary sewer, septic tank, or on-site sewage-disposal treatment facility. These systems are typically subject to all statutes that apply to public facilities. Most often, these systems are used by different people or groups of people over a period of time. Portable nonsewered waste disposal systems used by workers at places of employment are outside the scope of this standard. Minimum standards for these systems in places of employment are found in PSAI ANSI/PSAI Standard Z4.3-2025: Nonsewered Waste Disposal Systems at Places of Employment: Minimum Requirements.
