Portable Toilets in Qilian County

The deployment, product features, and technical requirements of portable toilets in Qilian County are as follows:

I. Procurement and Deployment
As an important part of Haibei Tibetan Autonomous Prefecture, Qilian County has continuously expanded the deployment scale of portable toilets. By 2024, a cumulative total of over 1,860 portable toilets have been deployed across the prefecture, with Qilian County adding 50 new portable toilets along highways in 2024. The average annual increase in demand remains stable within the range of 220 to 280 units. This data reflects the local emphasis on public sanitation facilities, with significant growth in demand, particularly in tourist attractions and along transportation routes.

II. Suppliers and Product Features

1. Qinghai Shiteng Metal Products Co., Ltd.: Provides portable toilets under the "Shiteng" brand, model 01, made of steel with a wood-grain finish. The product supports three sewage disposal methods: water flushing, packing, and foam sealing, suitable for parks, scenic spots, streets, and construction sites. The dimensions are 1.2×1.5 meters with a height of 3 meters. The main material is metal carved panels, with disposal methods including water flushing and eco-friendly packing. The unit price is 3,600 yuan each, with no minimum purchase quantity.
2. Guting Metal Products Joint Service Station: Establishes service stations in four locations, including Qilian County. The products feature a Q355B weather-resistant steel body with modular sandwich panel cladding, achieving a wind resistance rating of Level 10, suitable for high-altitude environments with strong ultraviolet radiation and freeze-thaw cycles. The restrooms and shower rooms support both independent power supply and grid-connected dual-mode switching, having completed -28°C low-temperature operation verification at the Aru Grassland Post Station. Additionally, the product exteriors can incorporate county cultural elements, such as adjusting panel colors and relief patterns, balancing functionality and aesthetics.

III. Technical Trends and Environmental Requirements

1. Customization and High-Altitude Adaptability: Starting from 2026, county-level procurement will prioritize suppliers with customized delivery capabilities. At an altitude of nearly 3,200 meters in Qilian County, portable toilets need to strengthen oxygen supply interfaces and double-layer vacuum insulation design to cope with the high-altitude, cold, and oxygen-deficient environment.
2. Environmental Compliance Upgrades: Since January 2025, Qinghai Province has implemented the "Technical Guidelines for Pollutant Control in High-Altitude Portable Toilets (Trial)", specifying requirements for fecal storage capacity, sewage treatment modules, and urine separation systems. Portable toilets in Qilian County must comply with these guidelines, such as adopting biodegradation, dry separation, or circulating water system technologies to reduce water dependency. Some high-end products have already applied sensor-based flushing devices that automatically flush after detecting the user's departure, further conserving water.
