Tianjin Marathon Portable Toilets

The setup, rental characteristics, and product advantages of portable toilets for the Tianjin Marathon are as follows:

Setup: The organizing committee has installed portable restrooms at the starting point, along the race route (every 1 kilometer from 2 km to 5 km, and every 2.5 kilometers from 7.5 km to 40 km), and at the finish line, covering the entire event's needs.

Rental Characteristics:

1. Adaptability: The racecourse in Nankai District, Tianjin, passes through historic streets, commercial areas, and residential zones, with high ground hardening rates and limited space. It requires balancing usage density, cleaning frequency, and site capacity.
2. Toilet Types: Direct-discharge toilets are the primary type, relying on built-in fecal storage tanks and chemical agents to decompose waste, eliminating the need for external water and electricity connections, making them suitable for narrow streets or temporarily restricted areas. Recirculating flush toilets are less commonly used due to their larger equipment size.
3. Quantity Allocation: Athlete toilets are allocated at a ratio of 1 per 60 participants, with the highest density at the starting point (1 per 50), followed by the finish line (1 per 55), and 3-5 toilets at every 2-kilometer refreshment station along the route. Spectator toilets are allocated at a ratio of 1 per 200 expected spectators and are placed away from athlete areas to prevent cross-contamination.
4. Cleaning Services: The cleaning schedule is inversely mapped to the event timeline, with the last cleaning at the starting point toilets completed 2 hours before the race starts. Toilets along the route are cleaned in batches based on athletes' passage times, with suction trucks traveling in the opposite direction of the racecourse to complete waste removal.

Product Advantages:

1. Space and Functionality: The box-type design features an interior height of 2.3 meters and a width of 1.2 meters, facilitating easy entry for athletes carrying bags. The foot-pedal dual-flush system conserves water (0.8 liters per flush), and solar photovoltaic panels power the exhaust fans and LED lighting, enabling off-grid operation. Wind-resistant anchors and adjustable ballast weights (50 kg) adapt to the coastal winds of the Binhai New Area.
2. Manufacturing and Quality Control: Local Tianjin enterprises employ rotational molding technology, enabling rapid mold opening and production of foldable toilet units (with a folded thickness of 30 cm) for easy transportation. Each unit undergoes a 72-hour full-water leak test and a 5,000-flush lifespan test to ensure zero defects.
3. Appearance and Services: 3D-printed personalized logos incorporate elements such as the Tianjin Eye and Liberation Bridge, blending with the city's landscape. Professional cleaning teams use environmentally friendly neutral cleaning agents to prevent corrosion of stone pavements. Local factories offer trial assembly and on-site debugging services, shortening logistics times, and introduce advanced foreign components for localized improvements.
