Portable Toilets for Factory and Construction Sites

Portable toilets for factory and construction sites are designed as fully movable facilities to meet temporary or permanent restroom needs in locations such as factories and construction sites, featuring cost-effectiveness and long service life.

I. Basic Components Portable toilets typically consist of core components such as fecal wastewater storage tanks (or disposal units), flooring, sanitary fixtures, walls, washing facilities, water tanks, roofs, and mobility devices. Some simplified portable toilets may use water storage tanks instead of traditional water tanks, for example, by adding universal wheels, toilets, and faucets to recycled water storage tanks to create a low-cost solution.

II. Classification by Structure and Mobility

1. Structural Forms
   • Single-unit structure: Designed as an independent unit, suitable for spaces with limited room, such as the 1.6-meter-wide double-squat-position products produced by a mobile toilet manufacturer in Henan.
   • Composite structure: Composed of multiple modules, it can be expanded into large public restrooms to meet high-traffic demands.
2. Mobility Methods
   • Lifting/handling type: Relies on lifting equipment or manual handling, suitable for short-term use scenarios.
   • Powered/trailer type: Equipped with engines or trailer devices, it can move autonomously or be towed by vehicles, such as the urgent customized product by Dezhou Hongtu Metal Products Co., Ltd. for a factory in Zhejiang, which completed a trailer-type portable toilet with 7 male squat positions and 1 female squat position within 4 days.

III. Classification by Sewage Treatment Methods

1. Water-flush and non-water-flush suction type: Flushed with water supplied from a water tank, with sewage periodically pumped out for treatment, suitable for construction sites with a water source and complete sewage disposal conditions.
2. Recirculating water-flush type: Equipped with a sewage treatment system to achieve water resource recycling, reducing water consumption, and suitable for water-scarce areas.
3. Dry-pack type: Uses biodegradable bags to collect feces, requiring no flushing, with regular replacement of the packing bags, environmentally friendly, and simple to maintain, commonly used in remote construction sites.

IV. Application Cases and Customization Portable toilets can be customized according to actual needs, such as adjusting the number of squat positions based on the gender ratio of factory employees (e.g., a design with 7 male and 1 female squat positions) or improving rain protection by widening the top eaves. Their modular nature allows for a short installation period, with some manufacturers able to achieve urgent delivery within 4 days to meet immediate needs.
