Hot Dry Season, Crowded Swimming Pools – Is the Water Safe for Your Family?

Vietnam’s dry season is arriving earlier, with consistently high temperatures from the very beginning of the year. Prolonged hot weather not only affects daily routines but also reshapes how families spend their leisure time—especially those with young children. As a result, swimming pools have become a popular weekend destination for many families.

However, as pool usage increases significantly during the dry season, one critical factor is often overlooked: swimming pool water quality. Water does not only need to look clean; it must be carefully managed to ensure safety, comfort, and suitability for all users.

Why Swimming Pool Water Quality Matters More in Hot Weather

As the number of swimmers increases, sweat, sunscreen, other cosmetics, and even environmental debris easily enter the pool, disrupting the chemical balance of the water. Under intense heat, chlorine—the most commonly used disinfectant—also evaporates more quickly, making it more challenging to maintain stable and effective levels. Without proper treatment and control, pool water can rapidly become cloudy and unstable.

In addition, improper or poorly controlled chemical use can lead to water that is technically “clean” but uncomfortable—causing eye irritation, dry skin, strong chlorine odors, or lingering discomfort after swimming.

The dry season also creates favorable conditions for bacteria and algae growth. Elevated water temperatures combined with strong sunlight can accelerate the proliferation of microorganisms if the water treatment system is not operating efficiently.

For these reasons, swimming pool water treatment during hot seasons must go beyond meeting basic safety standards. A more comprehensive approach is required—one that ensures consistent disinfection performance, enhances swimmer comfort, and supports sustainable pool operation throughout the peak season.

BWT Swimming Pool Solutions: Comprehensive Technology for Peak Season

To meet the growing demand for swimming pools during the dry season, water treatment can no longer rely solely on conventional disinfection methods. BWT develops comprehensive swimming pool technologies designed to effectively control water quality, enhance the swimmer experience, and support sustainable operation across a wide range of pool types—from private residential pools and residential complexes to hotels, resorts, and spas.

BWT UV Disinfection Systems – Safe, Chemical-Free Protection

One of BWT’s key technologies for swimming pool water treatment is the Bewades range of UV disinfection systems. This technology uses high-intensity ultraviolet light to eliminate bacteria, viruses, and microorganisms in the water—without the need for additional chemicals.

Thanks to its physical disinfection process, UV treatment significantly reduces chlorine odor and minimizes eye and skin irritation, common issues in pools operating continuously during hot weather. This makes it particularly suitable for families with children and frequent swimmers. BWT UV systems are designed for automatic operation and easy integration into existing pool systems. They are also environmentally friendly, as they do not generate harmful chemical by-products.

BWT Ozone Technology – Enhanced Efficiency for Superior Pool Water Quality

In addition to UV treatment, BWT applies ozone purification system for swimming pool water treatment. Ozone is a powerful oxidizing agent capable of rapidly destroying bacteria, viruses, and algae, while breaking down organic compounds that cause odors and water turbidity.

Integrating ozone into the treatment system significantly reduces the need for chemical disinfectants—especially chlorine—resulting in clearer water and a more comfortable swimming experience. During the dry season, when higher temperatures place greater stress on pool water quality, ozone plays a critical role in maintaining stable conditions and preventing microbial growth, even under heavy pool usage.

BWT Pool Robot – Supporting Daily Water Cleanliness

Beyond disinfection technologies, regular pool cleaning is equally essential during peak season. BWT offers a range of intelligent pool robots designed to efficiently clean pool floors, walls, and remove accumulated debris.

These robots operate automatically, reducing manual maintenance efforts and ensuring that pools remain clean and ready for use at all times. Prompt removal of debris also reduces the load on water treatment systems, enhancing disinfection efficiency and helping maintain water clarity for longer periods.

For residential pools, community pools, and hotels operating continuously during the dry season, BWT pool robots offer a practical solution to optimize time, costs, and overall operational quality.

Toward Safer and More Sustainable Swimming Pool Standards

As swimming pools become an integral part of family life during the dry season, water quality standards must be elevated accordingly. An ideal swimming pool is not only a place to cool off, but also a safe environment where children can play, adults can relax, and families can enjoy time together with peace of mind.

Through professional swimming pool water treatment solutions, BWT partners with residential communities, hotels, schools, and families to maintain stable water quality throughout the hot season. As a result, every swim delivers not only refreshing relief from the heat, but also a comfortable and reassuring experience for all users.
