In a natural swimming pool or swimming pond, the water is filtered for the most part by plants and lava rock. With an upflow solution (from the bottom to the top of the lagoon), the water flows towards the skimmers and is then discharged towards the lagoon. A prefilter (skimmer or sieve) retains large waste.
Natural pools allow you to enjoy the benefits of clean water without chemicals, while increasing the biodiversity of your garden - we explain everything
At Foudebassin, we explain to you how to build your own natural swimming pool. You can order our kits to build your entire pool yourself, except the block structure :)!
Under the lava stone (porous red gravel), perforated pipes are installed and suck up the water thanks to a hidden suction pump. As this water passes through the roots of the plants, nutrients are absorbed to help them grow. The purified water is then recirculated to the bottom of the bathing area.
For the swimming pool, which operates according to the 'downflow' principle, the lagoon area is delimited from the swimming area by a separating wall which is below the surface of the water and which supports slabs. The space created between the slabs will function as a kind of skimmer. The flow of water directs leaves and other dirt particles into the lagoon.
This is where the biological water filtration takes place: by means of marsh plants, such as yellow iris and a combination of porous stones such as lava rock and the filter mineral Clinopti Plus. The latter is an excellent carrier for useful bacteria, adsorbs harmful components and improves water quality. In the marsh area, a 'Drain connector' can function as a support for the drainage pipes and as a control well for the pump.
The swimming area is separated from the filtration area by a dividing wall which is lower than the water level and which is provided with 'Japanese steps' to give a skimmer effect. The flow of water directs leaves and dirt particles from the swimming area to the lagoon area.
Water purification happens here: by a combination of marsh plants like yellow iris and porous stones like lava. For a swimming pond, a layer of filter mineral 10 to 15 cm thick is generally provided, above the lava stones.
In the marsh area, a Drain Connector serves as a carrier for the drains and as a control well for the pump.
The advantage: very easy maintenance . The dirt settles in the area below the lagoon and can be removed say once or twice a year by the dirt remover of Pond Technics in which a cellar pump is installed. The skimmer retention baskets must be emptied regularly.
To weigh the pros and cons of building a swimming pool, it helps to look at the benefits of natural swimming pools. These include:
Planting a natural pool is essential. Of course, like any part of the garden, it will require maintenance — the aquatic plants will need to be cut back in late fall.
It should also be remembered that the term "filtration plants" can be misleading as the plants do not remove particles from the water. They actually absorb and capture nutrients from the water, which means algae (which feed on these nutrients) will not grow and bloom in the water.
The amount of nutrients a plant absorbs is more or less proportional to the amount of plant growth. So plants that grow "greener" take up more nutrients, but that can also mean they grow more aggressively.
