Maintenance
All the answers to your questions about sanitation and phyto-purification.
What should I do in the event of invasive plants?
Fireweed, willow, nettles, bindweed, etc. may appear in the initial composition of semi-aquatic plants in the sanitation garden.
These should be removed as they appear, so as not to be overwhelmed by unwanted plants that could eventually take over.
As soon as an unwanted plant emerges, it should be removed as quickly as possible to prevent it from spreading elsewhere.
During cutting and at the end of summer, more detailed maintenance can be implemented to take stock of the development of the plants, regulate some and remove any unwanted ones. Maintenance is fairly easy as the plants are rooted in gravel, which makes removal relatively easy.
Special care must be taken to avoid bindweed overwhelming the other plants, as it is very invasive and difficult to treat when it has taken hold.
Marigolds can be planted around the filter as a preventive measure because the roots contain acidity, which has the virtue of repelling bindweed.
Your local Aquatiris expert will also be able to work with you to find the most suitable solution during a visit to your installation.
How much does maintenance cost?
The maintenance contract should be considered at between €100 and €300 excluding VAT, depending on the desired formula (one or two trips, monitoring, cutting, weeding, etc.), to be defined with your local Aquatiris expert.
Should we remove the humus (residual deposit on the surface)?
No, definitely not! It contributes to the proper functioning of the filter. Humus is the system’s great “pantry”. It contributes to the correct “Water-Soil-Plants” balance. Bacteria develop favourably there, allowing the degradation of the organic matter and nitrogen contained in our wastewater and its absorption by plants.
How often should the reeds be cut?
At the end of February or beginning of March, when nature wakes up and prepares for the arrival of spring.
Does it require a lot of maintenance?
The filters have gardener-type maintenance (cutting, weeding, etc.). A maintenance booklet will be provided with the study. The first year is the most important for the shooting and growth of the plants.
The sludge composted on the surface of the filter planted with reeds must be removed approximately every 10 years using a claw or a rake and placed in a composting platform where it can be recycled.
Your Aquatiris expert can also intervene at your request to advise you on the maintenance of your Sanitation Garden and offer you a maintenance contract, if necessary.
Who should I contact in the event of a problem? An after-sales service?
We invite you to contact your local expert who is your preferred intermediary. You can find their email and telephone contact details on the contractual documents and on the website through our directory.
If you do not receive a reply, you can contact the Aquatiris after-sales service on (+33) 02 99 54 56 21.
How long does the system last?
As long as there is wastewater to feed it. The lifespan of the system is estimated to be comparable to the lifespan of the house.
Does the sand need to be changed?
No, the sand does not need to be changed, unlike other systems.
Should the plants be changed? What is their lifespan?
No, the initial planting is quite dense and the plants regulate themselves.
