What is a Natural Swimming Pool?

Swim in crystal clear, chemical free water

A natural pool or swimming pond is a swimming pool that's filtered and purified hydrobotanically by water plants and a biological filtration system. That means clear, hygienic, living water without the need for chemicals.

Biologically filtered, hygienic water

Native aquatic plants grow in the pool’s regeneration zones, absorbing nutrients from the water and helping keep the water balanced and algae at bay. Biotop's world-renowned filtration system ensures crystal-clear, hygienic water. And ultra-quiet, submerged pumps and a hidden hydraulic system work hard below the surface circulating the water through the filters without the need for a plant room.

Your eco-friendly garden oasis awaits

The result is a balanced, natural-looking pool with water that feels like wild swimming in a mountain lake: soft, sparkling and with an energy that's both rejuvenating and relaxing.

BioTop Filtration

Our natural pools and swimming ponds are fitted with Biotop biological water filtration technology. Together with water plants in special regeneration zones the water is kept sparkling clear and hygienic for swimming without the need for chemicals.



A submerged pump draws water from the skimmers through the pump chamber and back into the pool via pressure pipes in the form of jets, fountains, rills, cascades or water boulders. This ensures the water is constantly circulating in your pool and keeps the surface clear.



Water flows through skimmers mounted into the side of your pool, where debris is caught and filtered in a fine sieve. Special escape routes for wildlife ensure your pool is eco friendly.



Water is returned from the skimmer via a specially patented Carbonator. The carbonator is connected to air pipes buried in the ground, and draws Co2 from the soil into the pool, which regulates the pool’s pH and boosts water plant growth.


Swim Zone

The swim zone is separated from the regeneration zone by submerged walls. This allows free flow of water and is especially beneficial for thermal gain.


Bio Filter

Water flows vertically through the bio compact filter from top to bottom and is biologically cleaned along the way then returned back to the pool via a separate hydraulic system. Organic compounds and impurities are broken down by microorganisms resulting is crystal-clear, hygienic water.



Why choose a natural swimming pool?

Good for your body, mind, and spirit

Swimming in chemical-free, living water has proven health benefits and leaves you feeling energised and rejuvenated. 

Designed to fit your lifestyle and garden

Natural pools are a versatile place for family fun, al-fresco dining, relaxation and quiet contemplation, and reconnecting with nature. 

Low maintenance and low running costs

Low level maintenance requirements and low energy draws mean lower running costs with less maintenance than a conventional pool. 

Ecological benefits

Enjoy swallows dipping, dragonflies, newts and amphibians and underwater pond life tucked away in the planted areas. Around the water's edge you'll see pollinators, birds bathing and bats in the evenings. 

Giving a home to an abundance of wildlife, your pool will play a vital part in protecting our planet and take care of your health and wellness, naturally.
