Several sanitation systems are available to you depending on your needs and the topography of your land: Approved traditional systems, compact filters and micro stations.
The most well-known non-collective sanitation system is the all-water tank, which succeeded the “septic tank” of previous generations, with its drainage trenches or sand filter. These systems use the purifying power of the soil, in which bacteria digest the materials contained in the wastewater. The main advantage of these systems is that they are supposed to have “proven themselves” over time. The all-water tank operates without electricity and you can use it intensively part of the year and the other part less, it will not affect its proper functioning or its life span. This is particularly useful in the case of a second home.
The compact filter
It is a device that takes over the operation of a traditional system (a double purification physical and bacterial), but with a much greater compactness, which means that the system takes up less space. Compact filters consist of an all-water tank, followed by a filter. As in a traditional process, the all-water tank takes care of the pre-treatment of wastewater (separation of grease and settling of solids). The filter fulfils the same role as the traditional systems and is used to purify the water. To do this, a natural or synthetic material, called media, is used in the filter pack. This filter medium can be of different kinds: coconut fibres, coconut chips, zeolite, pine bark, hazelnut shells, rock wool…
The micro station treatment plant.
The micro-treatment plant is an all-in-one solution for wastewater treatment. It ensures both the pre-treatment and treatment. The principle is a breaking down of waste by microorganisms. These bacteria are favoured by oxygenation, created by an air generator.
There are two main families of micro-stations :
- micro-stations with fixed parts: bacteria are fixed on supports.
- micro-stations with moving parts: bacteria are suspended in water and sludge.
It should be noted that micro-stations operate with an electrical connection, they cannot operate intermittently and are therefore only suitable for a main home.
All sanitation facilities are subject to a pre-visit and final inspection controlled by the SPANC (public service for non-collective sanitation). This control consists of ensuring that all new installations are well adapted to the nature of the land and the dwelling they serve, meet current regulations and are installed correctly.
