Exploring the Health and Environmental Benefits of Natural Swimming Pools
15 Mar, 2024
Natural swimming pools present a welcoming alternative to traditional chlorinated pools, promising health and environmental benefits to accompany your relaxing pool days. As concerns are rising about chemical exposure and environmental sustainability, natural swimming pools have become a popular substitute. Unlike conventional swimming pools, natural pools utilise botanical filtration systems and aquatic plants to maintain the water quality, eradicating the use of chemicals and keeping the pool ecologically balanced. In this article, we explore the potential health and environmental benefits of natural swimming pools.
What Are Natural Swimming Pools?
Natural swimming pools are bodies of water that use plants and natural environmental processes to maintain the water quality, rather than chemical intervention. They are typically separated into two zones: the swimming zone and the regeneration zone. The swimming zone is the main body of water where everybody swims and enjoys the results. The regeneration zone is full of gravel and rocks, along with the water plants. Types of plants suitable for this area include water lilies, cattails, and reeds. A pump will circulate the water between the two zones, where the pollutants and water impurities are removed. The plants in the regeneration zone absorb the water contaminants. By circulating the water, it becomes oxygenated and therefore a more suitable and healthier environment for the aquatic life. The entire pool is lined with a water-tight membrane or constructed material to stop the water from draining into the ground.
In comparison, traditional chlorinated pools use chlorine as the main chemical to disinfect and remove the water impurities. The combination of chlorine with the pool water creates hypochlorous acid, which is a powerful chemical designed to kill bacteria and viruses. Chlorine pools also use a filtration system, consisting of sand or a type of filter to catch the contaminants. Pool pumps power this process and ensure that all of the water in the swimming pool gets cleansed.
Health Benefits of Natural Swimming Pools
Unlike chlorine, which can irritate eyes, bleach hair, dry out skin, and even cause respiratory problems, natural pools offer a gentle, chemical-free experience. This makes them the perfect choice for individuals with sensitive skin or allergies who may experience discomfort in traditional pools. It also allows swimmers to immerse themselves in a more natural environment which fosters a sense of well-being and relaxation.
Environmental Advantages of Natural Pools
Natural pools embrace a more harmonious approach with the environment. Because of the lack of chemical usage, they protect nearby ecosystems from harmful byproducts. Their clever design reflects nature’s own purification methods. By relying on natural filtration, natural pools minimize energy consumption and promote long-term sustainability. This eliminates the environmental footprint associated with chlorine production and chemical runoff, fostering a planet in better balance.
Design Considerations for Natural Swimming Pools
Natural swimming pools offer a unique opportunity to create a personalized backyard haven. They can be designed with either geometric lines or embrace a more organic free-form shape that incorporates waterfalls, boulders, and rocks. A key element is the shallow stone bed (100-200mm wide) separating the swimming area from the filtration zone. While the initial investment may be higher due to the specialised construction required, the long-term savings on maintenance are significant.
Plants are the heart of a natural pool’s ecosystem. They not only provide a beautiful aesthetic but also play a crucial role in water purification. Floating plants like water lilies and water hyacinths offer shade for beneficial microorganisms, while the root structures of many submerged and marginal plants act as natural filters, removing excess nutrients and contaminants. For effective algae control, a large surface area is recommended. To minimize algae in the first place, locate your pool in a partially shaded area. Floating plants can further suppress algae by limiting sunlight penetration. There are a diverse range of aquatic plants used for filtration like papyrus and reeds. Oxygenating plants that are rooted underwater such as pondweed and water hyssop. Beautiful flowering varieties like swamp hibiscus that also add colour and definition to the pool.
The beauty of a well-designed natural pool lies in its relatively low maintenance needs. However, some routine care is essential. This includes maintaining healthy plant life, preventing contamination from animals, and keeping warm temperatures below 85 degrees to ensure healthy bacterial growth.
Case Studies
The success stories of natural pools are readily available for exploration. Reputable publications like Better Homes and Gardens, Business Traveler, and the Wall Street Journal have showcased stunning natural pool installations, highlighting their beauty and functionality. Testimonials from satisfied owners abound, with the Association for Swimming Ponds and Natural Swimming Pools (ASPNSP) acting as a valuable resource. It has been said enthusiastically by people that they endorse biofilter pools, praise their low-maintenance nature, chemical-free operation, and pure healthy water. Companies specialising in natural pool installations often feature additional reviews and testimonials on their websites. By delving into these case studies and success stories, potential natural pool owners like you can gain valuable insights and real-world examples.
Common Myths and Misconceptions
One common concern is that leaves or insects will drastically change the water. However, the natural filtration system is designed to handle these organic materials. Similarly, moderate rain won’t disrupt the pool’s balance. Another myth is the need for constant testing – unlike traditional pools, natural pools achieve equilibrium without harsh chemicals, eliminating the need for frequent monitoring. Safety is also a top priority which can be seen through the lack of chemicals. While traditional pools require constant attention, natural pools offer a low-maintenance solution for a refreshing and healthy swimming experience.
During the initial weeks, provide extra care to your young ecosystem. Nurture your plants and allow the beneficial bacteria to establish themselves within the biofilter. Regular skimming and the occasional bottom vacuuming with a pool vacuum will further support the plants’ efforts. For maximum enjoyment, add solar-powered lights and strategically placed plants to deter unwanted visitors.
Future Trends and Innovations
The future of natural pools is filled with exciting possibilities. Emerging technologies like the “living microbial” filter, utilise beneficial bacteria and minerals for superior water quality. Sustainability advancements are also on the horizon. Infinity edges, once a luxury, may become more accessible, blurring the lines between pool and natural environment. Additionally, research into zooplankton populations within the pool ecosystem holds promise for self-regulating system, minimising our environmental footprint.
Summary
Natural pools present a compelling alternative to traditional options. They prioritize health and environmental well-being. Swimmers enjoy a chemical-free experience, free from irritation and harsh byproducts. The ingenious design fosters a thriving ecosystem within the pool itself, promoting biodiversity and reducing reliance on external resources. For those seeking a more sustainable and holistic approach to backyard recreation, natural pools offer a truly transformative experience.
