Chlorine Pools

A natural pool isn’t just an upgrade. It’s a paradigm shift in how we think about water, wellness, and the spaces we live in.

A New Relationship With Water

From Chlorine to Natural Clarity The Rise of the Organic Pool

Natural swimming pools don’t just feel better — they work better for the environment, your health, and your wallet:

  • Simplified permitting process: In many regions, including Portugal, natural pools are classified as ponds or water catchment systems rather than traditional “chemical” pools. This often means fewer bureaucratic hurdles, no hazardous chemical storage approvals, and in some cases, no formal building permit required at all.

  • No toxic chemicals: Nothing leaches into the soil, no fumes irritate the lungs, and no chemical disposal is needed.

  • Energy savings: Biological filtration and UV sterilisation require far less electricity than traditional systems — no 24/7 pump cycles or chemical feeders.

  • Healthier skin, eyes & lungs: Say goodbye to red eyes, dry skin, and inhaling volatile chloramines. Natural pools are safe for babies, pets, and even pollinators.

  • Protects biodiversity: Designed to support life, not kill it — natural pools attract dragonflies, frogs, birds, and butterflies.

  • Low maintenance: Forget chemical balancing. Once properly established, natural pools are self-regulating ecosystems.

  • Sustainable water use: Many systems double as rainwater collection basins and greywater reuse features — crucial for drought-prone regions.

Thanks to major technological advances in water treatment — namely UV sterilisation and biological filtration — natural swimming pools can now achieve the same level of clarity and safety as conventional pools, without any of the toxic byproducts.

What was once a dream is now a reality.

Imagine stepping out of a mountain lake: cool, vibrant water flows off your skin. You feel relaxed, rejuvenated, even healed.

Now compare that to a chemical pool — your eyes sting, your skin itches, your hair feels dry and lifeless. The sharp smell isn’t nature — it’s chloramines: a mix of chlorine, sweat, and urine.

That’s the difference between living water and chemically treated water. One reconnects you with nature. The other is just a means to swim.
