How many liters of make-up water must be added per bather per day?

The correct answer indicates that 20 liters of make-up water must be added per bather per day. This figure is based on standard practices in aquatic facility management, which take into account several factors such as evaporation, water loss due to splashing, and the need to maintain water quality and balance.

When operating a pool or aquatic facility, understanding the appropriate amount of make-up water ensures that the facility can maintain optimal conditions for health and safety. Insufficient make-up water can lead to water quality issues, affecting both the clarity of the water and the effectiveness of the sanitation systems. Regularly adding the correct amount of water prevents excessive strain on filtration and treatment systems, ultimately leading to a healthier and more pleasant environment for all patrons. This knowledge is essential for staff to effectively manage the recreation space and provide a safe experience for those using the facility.
