Building a natural pool rather than a classic pool: a sustainable alternative
What is a natural pool?
Natural pools, also known as biological pools, represent a sustainable and aesthetic alternative to traditional swimming pools. Their main advantage lies in their chemical-free operation. Unlike classic pools that require the use of chlorine or other disinfectants to keep the water clean, natural pools rely on biological ecosystems to filter and purify the water.
Their system is based on two main zones:
- The swimming zone: where the water is clear and accessible to swimmers.
- The regeneration zone: composed of aquatic plants, specific substrates like gravel or lava rock, and sometimes microorganisms that act as natural filters.
Aquatic plants absorb nutrients present in the water (nitrates, phosphates) and thus limit the proliferation of algae. In parallel, the substrates retain particles and promote the growth of beneficial microorganisms that decompose impurities.
The benefits for the environment and health
In addition to the absence of chemicals, natural pools offer a healthier swimming environment. The water, purified ecologically, does not give off unpleasant odors and does not cause skin or eye irritations, which are common with chlorine. Moreover, these pools contribute to biodiversity: they attract insects, birds, and amphibians that participate in the natural balance.
In terms of water consumption, a natural pool is particularly advantageous. Once filled, it requires little supplemental water, as it limits losses due to evaporation.
Good to know: maintaining a biological pool can reduce water consumption by 30% to 50% compared to a classic pool.
Recent innovations
With current environmental challenges, specific innovations have emerged to further improve the functioning of natural pools. Here are some notable advances:
- Aquatic plants adapted to arid climates: These plants, recently introduced to the market, are more resistant to drought periods and require less water. They perfectly meet the needs of regions in the south of France regularly affected by water restrictions.
- Recycled substrates: Biological filters are now available in recycled materials, such as crushed glass or ecological aggregates. This evolution reduces the carbon footprint of installations while improving their performance.
- Hybrid systems: A new generation of natural pools combines biological zones and advanced filtration technologies, such as UV or low-consumption electrolyzers. These systems guarantee clear water, even during periods of high traffic or in difficult climatic conditions.
Practical advice
When installing a natural pool, prioritize the use of local plants. These plants are better adapted to climatic conditions and require less maintenance. In addition to reducing costs, this approach strengthens the integration of the pool into the surrounding landscape and promotes a balanced ecosystem.
Building a classic pool but with sustainable and environmentally friendly materials
Even if natural pools offer an attractive alternative, it is entirely possible to build a classic pool while adopting an environmentally friendly approach and transforming it into an ecological pool.
What materials for an eco-responsible pool?
Concrete, the basic material for building many pools, can now be replaced or optimized with low-carbon concrete, which reduces CO₂ emissions by up to 30% compared to its classic equivalent. Moreover, the use of biodegradable or recyclable liners represents an interesting alternative, combining performance and environmental preservation.
Another idea, recycled natural stone or porcelain stoneware coatings offer timeless aesthetics, but also better integration into the environment. Porcelain stoneware, known for its durability and resistance, is now available in versions made from local and recycled materials, thus reducing the carbon footprint linked to their production and transport.
Focus on recent and upcoming innovations
Recent progress makes it possible to offer even more environmentally friendly solutions. Among them:
- Innovative coatings: Finishes based on biodegradable and aesthetic composite materials, such as textured liners imitating stone or wood, are expected to become widespread in the coming years.
- Use of local raw materials: To reduce transport costs and carbon impact, more and more manufacturers favor locally sourced materials, particularly for coping and exterior coatings.
- Recycled structures: Some manufacturers already offer prefabricated pools made from recycled plastics or metals, offering a reduced carbon footprint.
Practical advice
To minimize environmental impact from the design stage, favor a circular approach by reusing existing materials, such as coping or border stones, when renovating or extending a pool. Consider integrating local materials that not only reduce the carbon footprint but also enhance the harmony of your pool with its natural environment.
Thus, even for classic pools, it is possible to significantly reduce their ecological impact by opting for sustainable materials and responsible practices.
Equip a classic pool with modern and eco-innovative technologies
After opting for sustainable materials in the construction or renovation of your pool, it is possible to go even further by integrating modern and eco-innovative technologies.
