Natural Filtration Swimming Pools: Everything You Need to Know

What is a natural pool?
A natural filtration swimming pool is a pool that does not require any chemicals. The filtration of the water is done naturally through plants that have "cleaning functions".

Why should I choose a natural pool?
The classic chlorine pools are still the first choice for the general public.

So what are the benefits of a natural pool?

Absence of chemicals:
As already mentioned, the main interest of these swimming pools is the absence of chemicals such as chlorine, which causes health and environmental problems. Studies have shown that chlorine, used as a disinfectant, irritates your lungs and aggravates respiratory disorders such as asthma, not to mention the burning sensations in your eyes and throat while swimming.

At the environmental level, wastewater containing chlorine is likely to eliminate microorganisms (bacteria, fungi, etc. ...) that are beneficial to the ecosystem.

Low operating and maintenance costs:

Compared to conventional pools, these eco-friendly basins are easier to maintain and operate thanks to the fact that they are almost autonomous.
By choosing a classic pool you need to think about water reruns, suction, filtration and wastewater treatment. With a natural pool, all you have to do is integrate the right plants and have a green thumb to properly maintain your ecological pond.

With the plants integrated into your pool, you will be in harmony with nature and will have the impression that your pool is an extension of a forest.

How does a natural swimming pool work?
The principle of a natural swimming pool is based on purification and regeneration zones which are constructed wetlands that aims to purify water.
You need 3 zones in your pool: a bathing area, a purification zone and a regeneration zone. In the  last two zones, impurities are filtered through plants that have a purifying function and the water is re-oxygenated through plants that generate oxygen.

For 20 square meters of bathing area you need, in all, 100 square meters of space for your natural pool.

How to maintain a natural filtration pool?
Natural filtration pools need to be maintained regularly despite the misconceptions surrounding their self-sufficiency. Indeed, it is an ecosystem that finds its balance by itself. But this does not preclude the fact that you need to clean it regularly.
The ease of maintenance depends on the beginning of your work, the vegetation you have installed and the space you have dedicated to your swimming pool.

Here is a  list of the tasks that you need to do to maintain your natural pool:

  • Aspirate trash such as tree leaves or other debris
  • Brush the liners
  • Remove algae if there is any
  • Analyze the pH of water and its components
  • Prune the plants if necessary.

Having a natural filtered pool has many ecological and landscape benefits. Its installation may be somewhat expensive, but it is a long-term investment given the cost of operation and maintenance of these pools. You just need to have a green thumb to take care of this part of your garden.
