what it is and how does it work on a farmland

Swimmable, natural, and sustainable

A biolake is a natural body of water, usually built in-ground and surrounded by greenery, that people use to relax and swim while fully respecting the environment. The difference between biolakes and regular swimming pools is that no chemical substances are used, like chlorine, to purify water. Instead, a system employing organic phytodepuration is preferred. This system uses water plants for oxygenation.

By choosing to realize a biolake in your garden or on farmland, you can enjoy a beautiful body of water that can be adorned with many different flowering water plants that also function as purifiers.

What are the advantages of a biolake or biopool?

  1. Low environmental impact
  2. Thanks to the absence of chlorine or other chemical substances, the water is highly tolerable and delicate for your skin
  3. it is low-effort maintenance as water does not need to be emptied. You can simply refill the lake or the pool a little during seasonal change
  4. it fills your garden with beauty 365 days a year, as a natural pool does not need to be covered


A biopool is a customized product that is suited to fit the needs of the surrounding environment. Biolakes and biopools are realized so that they can complement perfectly within the environment without damaging its balance.
In case you want to realize a homemade biopool you need to take into account several aspects, such as possible slopes of the ground, exposure to sunlight, and proximity to tress.

In order to realize the perfect biolake you need to consider that it will be divided into two different areas at least:

An area for relaxing and bathing
A narrower area, the regeneration area (30% of the entire surface). The water plants will be inserted into this area so that they will contribute to creating a system of organic phytodepuration.
The regeneration area has to be narrower and covered by a suitable substrate for each plant, along with volcanic lapillus or expanded clay, which are both essential to ensure the correct growth of your plants and a good oxygenation of the biolake.

What permits are needed to build a homemade biopool?

To make your homemade biolake or biopool, you will definitely need to ask for a specific permit from your municipality. Legally speaking, it is quite easy to obtain one. However, it might take longer, depending on the size of the project or the region you live in. You can contact your municipality and ask what permits are needed in your area. A biolake is not usually classified as a luxury good. Therefore, you would not need special authorizations or limitations related to the land registry.

In case you want to set up a biolake in a public area, like a park, the situation is quite different. In this case, you need to request permits from both the municipality and local health authorities, whom they verify the wholesomeness of the water.
