MaintainlyHow often does the SPANC inspect a septic system in France?
SPANC septic system inspection every 8 years. The commonly recommended range is at least every 10 years; your SPANC sets the interval. A failing system pollutes groundwater, and an out-of-date report delays a sale.
French homes that are not connected to mains drainage have an individual system (assainissement non collectif), inspected by the SPANC of the commune or group of communes. The SPANC must check that the system works and is maintained at least every ten years, and the commune sets the exact interval in its service rules. The visit is compulsory and charged for, and the SPANC sends notice at least seven working days ahead.
Why does a SPANC septic inspection matter?
A failing system pollutes groundwater, and an out-of-date report delays a sale.
What happens if you skip a SPANC septic inspection?
If the system is a health danger or an environmental risk, the owner must bring it into compliance within four years. When you sell, the SPANC report attached to the sale agreement must be less than three years old, and any works it requires must be done within one year of signing the deed. Refusing the inspection can bring a charge at least equal to the sanitation fee, which can be increased by up to 400%.
What does the professional actually do?
- Checks that the system works and is being maintained
- Checks that it is accessible and looks for wear and maintenance defects
- Assesses any danger to health and risk of pollution
- Issues a report stating whether the system is compliant, and any works required
How do you choose someone qualified?
The SPANC for your commune carries out the inspection; you do not choose the inspector. Emptying the tank is separate: it is done by the commune where it offers the service, or by a company approved by the departmental prefect (vidangeur agréé), whose receipt you should keep.
How do you know a SPANC septic inspection is overdue?
- A letter from the SPANC
- Planning to sell in the next three years
- Smells, slow drains or wet ground over the drainage field
What do people get wrong?
- Burying the tank lids so they cannot be opened
- Not keeping the paperwork from each emptying
When should you stop and call someone?
Always for the inspection. Have the tank emptied by an approved company before the sludge passes half of its useful volume.
Does this differ in the US, UK, Australia or Canada?
United States
The EPA does not regulate single-family septic systems; states and local health departments do. Many states require an inspection when a property is sold, and the EPA recommends an inspection every 1 to 3 years.
United Kingdom
In England, the general binding rules do not allow a septic tank to discharge straight into a watercourse. There is no periodic inspection by the regulator; the rules require sludge to be removed before it exceeds the system’s capacity, by a registered waste carrier.
Australia
Onsite wastewater rules are set by states and local councils. Ask your council what it requires for your type of system.
Canada
Rules are provincial and municipal. Ask your municipality whether it runs a septic inspection programme.
What about in Europe?
France
Inspected by the SPANC at least every 10 years, at an interval set by the commune. The report must be under 3 years old when you sell.
