Professional configuration of a large competition pool
The core configuration of a large competition pool mainly includes these four aspects: swimming pool body and lanes, water treatment and water quality, competition-specific facilities, and safety and auxiliary facilities.
1，Swimming pool body and lanes
Dimensions: Length 50 meters (+0.010/-0.000 meters tolerance), width 25 meters (permanent facility).
Lane width: 10 lanes required for international competitions, each 2.5 meters wide.
Water depth: ≥2.0 meters.
Water temperature: Constant at 25-28°C.
2，Water treatment and water quality
Circulating filtration: The filtration rate needs to reach 220-250 m³/h.
Water quality monitoring: At least three automatic and manual tests daily, with regular analysis by an independent laboratory to ensure clear water and chemical balance.
3,Competition-specific facilities
Starting block: 0.5m x 0.5m, with the front edge 0.5-0.75m above the water surface; must be equipped with a backstroke hand grip.
Automatic timing system: Equipped with a touchpad (2.4m x 0.9m), accurate to 0.01 seconds.
Lane markings: Dark contrast lines on the pool bottom, 0.2-0.3m wide, with prominent T-shaped crossovers at both ends.
4,Safety and auxiliary facilities
Poolside and Climbing Ladders: The starting pool edge must be at least 10 meters wide, and the remaining edges at least 5 meters wide. There must be 4-6 embedded climbing ladders within the pool.
Accessibility and Emergency Response: At least two accessible entry methods (e.g., lifts, ramps); equipped with AEDs and other first-aid equipment; and a clear emergency evacuation plan.
Lighting: Olympic-level events require a water surface illuminance of at least 1500 lux, uniform and glare-free, meeting the requirements for high-definition broadcasting.
