All about Natural Pools

A natural swimming pool or pond is a pure ecological system where the water is protected from chemicals and  plants are used in the enviromnent to balance the ecological system. The purifying of the water is made by biological filters or natural plants. It is called natural pool because the system has biological equivalents in the natural world. Natural pools are called  NSP (Natural Swimming Pool or Natural Swimming Pond).

The natural pool is divided into two areas:

  • The swimming zone is the area intended for swimming that resembles a conventional swimming pool or pond.
  • The regeneration zone consists of a lined overflow pool filled with specific filtration substrate and flora. Plants used for water regeneration can be supplemented with decorative flowering species to create an attractive water garden environment. The biological processes that clean the water take place in this zone.

Pool Filtration System

Skimmer and pumps makes the water circulate through the regeneration area and then the water returns to the swimming area. Natural plants filters contaminants and nutrients in the water prevents algae. Natural rocks works like biological filters thanks to attaching environmental friendly bacteria.

The water in a natural pool is “living” and does not need to be connected to a sewer and costs of energy and mechanical operation is reduced. A natural pool welcomes also living creatures like frogs, snails and other naturally living creatures in an ecological system. It is a good sign of having a pure natural system. In a natural pool you do not have issues with itching skin, red eyes, allergies or damaged bathing suits that chlorine filled waters causes. You can also connect your pool with heat pumps or solar energy to heat up the water and cover the electrical usage of pumps, lamps ecc.

When planning a natural swimming pool please consider following:

– Minimum depth of 2 m

– For correct purification the regeneration- and swimming zone areas must be equal

– Swimming zone be physically separated from the regeneration

– There are no fixed standards for a pool, each structure has to be adapted to local circumstances and climate

– You can swim immediately, but it takes 2-3 years to reach full biological equilibrium

Even if a natural pool needs much less maintenance than a classical chemical pool, a seasonal care is still needed:

° Spring: Plants must be pruned and cut to avoid over growth, like in a normal garden. Minimize foreign contaminants from all areas.

° Summer: Hot days the water may evaporate and the pool may need extra water to protect the system

° Autumn: Remove dead leafs and prevent algae growth

° Winter: Avoid to extend the freezing process of the pool during the winter as it can damage to pool. The pool is already calculated to manage local temperatures.
