You might not think twice about the pool’s ecological impact before diving in. But here’s a fact that may surprise you: traditional swimming pools can use up to 40,000 liters of water per year, not to mention the chlorine and other chemicals that linger long after a splash. Imagine that!
Now, imagine a pool designed to work with nature, not against it—one that uses biological filtration, zero chlorine, and attracts local wildlife. That’s a natural pool for you. It’s a luxury, yes, but also a leap toward sustainable living that’s catching on in Portugal.
Whether you’re after a chemical-free swim or a backyard sanctuary that rivals a natural lagoon, choosing the right company is key. In this guide, we’ve narrowed down the top Portuguese experts who build stunning, eco-conscious pools and ponds.
Think crystal-clear water filtered by plants, lush landscapes, and timeless aesthetics that put nature front and center. Let’s dive in and explore the best professionals in Portugal ready to turn your pool dreams into reality—naturally.
What Makes a Natural Pool or Bio Pool?
Natural pools are unique because they redefine what a pool can be. Unlike traditional pools that rely on chlorine or synthetic filters, natural pools use biological systems to maintain water purity.
In these systems, plants, microorganisms, and carefully chosen filtration zones work together to create a self-sustaining, chemical-free environment. The pool itself is divided into two sections: the swimming zone and the regeneration zone.
The swimming zone is designed for relaxation and activity, while the regeneration zone, often featuring aquatic plants, serves as a natural filtration system that cycles the water, removing impurities and maintaining a delicate ecological balance.
Bio Pools
Bio pools, in particular, are slightly different in design from traditional natural pools. While natural pools mimic the feel and structure of lakes or ponds, bio pools are more controlled and customizable, making them ideal for those who want a natural-looking pool with minimal plant coverage. Instead of large vegetation areas, bio pools use special biological filters and a small area of plants that work together to maintain clean, clear water without chemicals.
Natural Ponds
Natural ponds are another variation that offers an even more rustic look, featuring a larger area of plants and encouraging biodiversity by attracting local wildlife. These are generally intended more for aesthetic purposes or as a habitat for small fish or amphibians than for swimming, although they can be made suitable for light swimming use.
Benefits of Natural Pools
The benefits of natural pools go beyond just ecological impact. They’re typically lower-maintenance than traditional pools, relying on natural processes instead of weekly chemical treatments. Additionally, natural pools create a unique atmosphere that feels more like a private lake or oasis than a standard backyard pool.
This not only enhances the space aesthetically but also positively impacts local ecosystems, providing habitats for plants, insects, and birds that might otherwise have been excluded. A natural or bio pool is an ideal solution for anyone interested in a low-maintenance, sustainable, and visually stunning addition to their property.
What to Look for in a Natural Pool Company
Choosing a company for a natural pool project is a big decision, as these projects demand specific expertise and ecological awareness. A company with a strong background in eco-friendly design and water treatment is essential for ensuring the health and longevity of the pool’s ecosystem. Here are the key factors to consider.
Design and Ecological Expertise
The best natural pool companies employ a multidisciplinary approach, combining landscaping with ecological design principles. Look for companies with a history of creating natural, sustainable pools that integrate seamlessly with the environment.
Many companies offer customizable design solutions that take into account factors like soil type, local plant species, and climate, ensuring that the pool will not only look natural but will also thrive in its location.
Materials and Plant Selection
The choice of materials and plants is critical in natural pool construction. Companies should use locally sourced, eco-friendly materials like stone, gravel, and native plants. Native plants are particularly important because they’re more likely to adapt well to the local climate, reducing maintenance needs and supporting local biodiversity.
Some companies, like Bio Piscinas, specialize in using plants that naturally thrive in Portuguese landscapes, ensuring their pools are both functional and beautiful.
Portfolio and Client Feedback
Reviews from previous clients can provide valuable insights into a company’s strengths and weaknesses. Look for companies with consistently positive feedback, especially regarding the pool’s long-term functionality, ease of maintenance, and aesthetic appeal.
A robust portfolio with a variety of completed projects is also a good sign that a company is experienced and adaptable. Client testimonials on platforms like Google Reviews or specialized home improvement websites can give you an idea of each company’s strengths and any potential areas of concern.
Aftercare and Maintenance Services
Natural pools may be lower-maintenance than traditional pools, but they still require specific upkeep.
Choose a company that offers maintenance packages or training on how to care for the pool to ensure that the plants and filtration systems continue functioning effectively. Some companies even offer annual maintenance checks or training sessions to keep clients informed on best practices.
With these considerations in mind, you’ll be better prepared to choose a natural pool company that matches your vision and goals for an eco-friendly, low-maintenance pool.
