Natural alternatives for swimming pools

Eco or natural swimming pools have been around for quite some time and offer an alternative to any homeowner wanting a more eco-friendly alternative to a chemically-treated swimming pool. These types of swimming pools rely on natural filtration for healthy water treatment.

The idea behind an eco or natural swimming pool is to offer low maintenance, lower costs to run, and perfect water quality – without the need for chemicals such as chlorine and hydrochloric acid.An eco or natural pool is a healthy pool that relies on natural filtration using plants and the promotion of organisms that keep the water clean. When you think of a traditional pool that relies on chlorine to kill off organisms in the water, which would you prefer to dip your body into… water that has been chemically treated, or energy-infused water that is natural and life sustaining?Natural swimming pools can be designed to fit into any residential garden layout, or to emulate lakes and ponds as they occur in nature. In fact, the only difference between installing a conventional swimming pool or a natural pool is that a traditional swimming pool uses chemicals to kill off bacteria, whereas a natural pool works in harmony with nature to cleanse and purify the water organically.

There are now several eco and natural pool installation companies throughout South Africa, offering a variety of eco and natural pool alternatives in a variety of shapes and styles.




What you should know about a natural swimming pool:

  • A natural pool is designed to incorporate two elements: the pool itself and the plant filtration section. The plant portion, or regeneration zone, is separated from the swimming area by the wall just below the surface of the water. The plants used for pool filtration are not normally part of the swimming area but are situated alongside the pool with a dividing wall. Alternatively, the plant filtration system can be located completely separate from the pool and linked via pipes.
  • Natural pools are designed to be self-cleaning as much as possible and they only require occasional maintenance to clean out leaf skimmers and vacuum the swimming section when used frequently during the warmer months of the year.
  • Whereas a traditional pool uses chemicals to control algae and bacteria, natural pools rely on plants to filter and clean the water – leaving nothing behind to allow for the growth of algae or bacteria.
  • Natural pools are not only environmentally healthy they are also energy efficient. The use of smaller pumps means less electricity is required for daily operation, by up to as much as a 60 percent saving when compared to a traditional pool.


There are a varied selection of plants that are suitable for planting in a natural swimming pool and you can buy these locally at garden centres or nurseries that specialise in plants for ponds and water features.
With our beautiful climate that provides us with abundant warm weather, adding an eco or natural swimming pool should definitely be something to consider if you are looking for a healthy and low maintenance solution for splashing around to cool down during the hot summers.
