Mobile Toilets at the South China International Expo Venue
The mobile toilets at the 10th South China International Expo venue effectively met the sanitation needs and maintained environmental hygiene during the event through government procurement of services, scientific facility allocation, rational quantity distribution, and the adoption of eco-friendly technologies.
I. Project Implementation Entity and Support Model
The Kunming City Administration Bureau entrusted Kunming Kangting Environmental Sanitation Equipment Co., Ltd. with the task of providing mobile toilet services through a government procurement approach, with a contract value of 147,800 yuan. This model clarified the responsible entity, ensuring professional and standardized services, and provided institutional guarantees for subsequent facility allocation, maintenance, and management.
II. Facility Allocation and Daily Maintenance Standards
The mobile toilets were equipped with no fewer than 50 toilet stalls, each containing basic functional facilities such as squat toilets, handwashing basins, coat hooks, makeup mirrors, door locks, and flushing devices to meet basic usage needs. Additionally, sufficient supplies of toilet paper, hand soap, and other consumables were required, and a professional team was formed to handle cleaning, fecal removal, and water replenishment, ensuring continuous usability and hygiene standards. This configuration balances practicality with attention to user experience.
III. Quantity Distribution and Dynamic Adjustment Strategy
The layout of mobile toilets around the venue followed the principle of "key area coverage + dynamic adjustment": Liujia Street added five mobile toilets around the Dianchi International Convention and Exhibition Center, prioritizing placement in high-traffic areas such as bus stops and parking lots, with installation completed by May 30th. Other reports indicated that four toilets were set up in the temporary parking lot on Convention and Exhibition West Road, one each was built under the approach bridges of Gate 4 and Gate 9, and two additional mobile toilets were installed around the venue. This multi-point coverage effectively dispersed pedestrian pressure and avoided local congestion.
IV. Technological Features and Environmental Benefits
The newly added mobile toilets employed foam sealing technology, which sealed the surface of excreta with foam. This technology offered two main advantages: first, it was water-saving and eco-friendly, reducing water consumption by approximately 90% compared to traditional flush toilets; second, it had a significant odor control effect, as the foam layer isolated the spread of odors, enhancing user comfort. This technology aligns with the green exhibition concept of large-scale events, balancing functionality and sustainability.
V. Service Objectives and Actual Outcomes
By dynamically adjusting the locations and quantities of mobile toilets, the pressure of queuing for toilets during the exhibition was alleviated, and environmental hygiene was well-maintained. This achievement was attributed to scientific planning in the early stages, efficient execution in the middle stages, and continuous maintenance in the later stages, providing replicable experience for public toilet support in subsequent large-scale events.
