Portable Toilet with Fecal Storage Tank
The portable toilet with a fecal storage tank is a type of portable toilet that typically includes a core structure such as a fecal sewage storage tank and may belong to the dry-packing type of portable toilet. Here is a detailed introduction to portable toilets with fecal storage tanks:
Core Structure
The core structure of a portable toilet with a fecal storage tank is the fecal sewage storage tank (or fecal sewage disposal unit), which serves to collect and store the feces and sewage produced by users. This structure is a key feature that distinguishes it from other types of portable toilets, ensuring independent treatment and temporary storage of excreta. In addition, the basic components of a portable toilet also include a floor, sanitary fixtures (such as toilets or squat pans), walls, washing facilities (such as sinks), a water tank (for storing flushing water), a roof, and mobility devices (such as wheels or towing structures). These components together form a complete portable toilet unit.
Classification Basis
According to the sewage treatment method, portable toilets can be divided into four major categories: water-flushing, waterless suction, recirculating water-flushing, and dry-packing types. Portable toilets with fecal storage tanks may fall into the dry-packing category. Their principle is to directly collect excreta using special materials or packaging bags without the need for water flushing, with the fecal sewage storage tank serving this function. Such toilets are particularly suitable for scenarios where water is scarce or where it is impossible to connect to a sewer system, such as outdoor events, temporary construction sites, or disaster relief sites.
Design Innovations
With technological advancements, the design of portable toilets with fecal storage tanks continues to be optimized. For example, the new lightweight plastic portable toilet in 2026 adopts a combined design of a large-capacity clean water tank and a gravity-flushing sewage tank, equipped with a foot pump for manual flushing. This design, while retaining the fecal storage function, improves flushing efficiency and user experience through the synergy of gravity and the foot pump, while maintaining the structural lightness and mobility.
Application Scenarios
The portability and independence of portable toilets with fecal storage tanks make them widely applicable in temporary or mobile demand scenarios, such as music festivals, sports events, and construction sites. Their feature of not requiring water and electricity connections also makes them an ideal choice for remote areas or emergency scenarios.
