Portable Toilet

Portable toilets are facilities that can be moved as a whole and provide toilet services to the public, suitable for various locations and available in multiple types and structural forms.

Definition and Composition

A portable toilet (Portable toilet) refers to a facility that can be moved as a whole and is set up at locations with fixed or temporary needs to provide toilet services to the public and customers. It generally consists of a fecal sewage storage tank (or fecal sewage treatment device), floor, sanitary ware, walls, washing equipment, water tank, roof, and mobile device, etc.

Development History and Materials

Initially made of materials such as wood, they had simple structures and functions and were prone to absorbing odors. Later, they gradually evolved to use materials such as fiberglass-reinforced plastic and polyethylene, which are more durable and less likely to produce odors.

Classification by Structure and Mobility

• By structural form: They are divided into single-structure portable toilets and composite-structure portable toilets. Single-structure ones are relatively simple and independent, while composite-structure ones may be composed of multiple parts and have more complex and diverse functions.
• By mobility: There are lifting and handling-type portable toilets, which rely on lifting equipment or manual handling for movement; and powered and towed-type portable toilets, which can be moved by power drive or being towed by other vehicles.

Classification by Sewage Treatment Method

• Flush and non-flush suction types: Flush types use water to flush the toilet, while non-flush suction types use a suction device to treat fecal sewage.
• Recirculating flush type: It recirculates and reuses the flushing water, saving water resources.
• Dry packing type: It packs feces and other waste with special materials for easy cleaning and transportation.

Features and Suitable Locations

They have the advantages of being movable, combinable, and easy to transport, allowing them to be conveniently carried to any location where toilets need to be set up and can be used repeatedly. They are suitable for stations, docks, tourist attractions, villa areas, newly built residential areas, large construction sites, squares, densely populated public places, and bustling commercial streets, etc.

Design Principles

They should follow the principles of being mobile and convenient, economical and durable; environmentally friendly and beneficial to the environment; improving efficiency and promoting humanity. The overall structure should be lightweight, using lightweight and durable materials, with a sturdy structure, controlled toilet height and width, and complete and reasonable mobile devices.

Market Types and Materials

On the market, there are various brands and types such as waterless packing portable public toilets, foam-sealing portable public toilets, flush-type portable toilets, and solar-powered portable toilets. Materials include stainless steel, steel structure, color-coated steel, and fiberglass-reinforced plastic, etc.
