Zhangbei Small Portable Toilet

There are small portable toilets in Zhangbei that meet the needs, with designs that combine modular structures and mobile deployment technologies to satisfy usage requirements in both temporary and fixed locations.

1. Technical Basis of Portable Toilets

In the 2026 integrated toilet procurement project of the Zhangbei County Housing and Urban-Rural Development Bureau, some public toilet designs explicitly feature portability or modularity. The core lies in integrated foundation technology: through processes such as the removal of original dry toilets, earth excavation, foundation compaction, and the pouring of threaded steel reinforcement bars, a standardized foundation platform is constructed, while also completing the connections of water supply pipes, power sources, sewage pipes, and septic tanks. This design allows the main body of the toilet to be quickly separated from the infrastructure, facilitating overall lifting or modular transportation, and providing technical support for mobile deployment.

2. Modular Structure and Functional Design

Some public toilets in the project adopt a modular design, independently dividing functional areas such as management rooms, public halls, and restrooms, and connecting them through standardized interfaces. For example:

• Relay Station Public Toilet: With dimensions ≥ 8360mm × 4560mm × 3500mm, it includes men's and women's restrooms, a disabled restroom, a management room, and a public hall, offering complete functionality and a compact structure;
• Public Toilet in Front of the Transportation Law Enforcement Bureau Square and Horse Ranch House Public Toilet: These are larger in size (≥ 12000mm × 5500mm/5000mm × 3200mm), with similar functional divisions but achieving flexible expansion through modular combinations.
  Such designs allow for the addition or removal of modules based on site requirements, such as retaining only the restroom module as a small portable toilet or adding a management room module to enhance functionality, meeting customized needs for different scenarios.

3. General Characteristics of Portable Toilets

Small portable toilets on the market generally possess the following characteristics, consistent with the design philosophy of the Zhangbei project:

• Materials and Structure: They use lightweight and durable materials such as fiberglass, steel structures, or color-coated steel, with a frame structure that supports lifting and transportation, offering strong wind and earthquake resistance;
• Sewage Treatment Methods: They support various technologies including water flushing, waterless suction, circulating water flushing, and dry packing, adapting to areas without sewer systems or scenarios with high environmental protection requirements;
• Application Scenarios: They cover temporary or fixed locations such as stations, docks, tourist attractions, and construction sites, enabling rapid deployment and reuse.

4. Pricing and Selection Recommendations

The prices of small portable toilets vary significantly depending on materials, functions, and customization needs, with a market range of 500 yuan to 9500 yuan. For long-term use, it is recommended to choose products made of steel structures or fiberglass, balancing durability and cost; for short-term events, basic models made of color-coated steel can be selected to reduce costs. Additionally, the sewage treatment method can be chosen based on actual needs, such as prioritizing circulating water flushing in areas with high environmental protection requirements and using dry packing in water-scarce regions.
