Attention to after-sales service
An approved equipment must benefit from a traceability from the manufacturing to the installation and the after-sales service. The devices marketed by large-scale material stores do not often benefit from an operational after-sales service network close to the user. These networks can therefore easily discount their products. On the other hand, the quality of the follow-up often leaves something to be desired.

The choice of a local distributor must guarantee a competitive cost for the installation and the follow-up of the operation of your installation.

The installation conditions are the main variants of the final installation cost:

• Ease of access to the work area without the risk of damaging asphalt, vegetation, curb walls, gables, pipes...
• The number of outlets around the house.
• Strong slope which imposes specific conditions mentioned in the user guide.
• Recognized flood zone.
• Areas with heavy snowfall or very cold weather (protection of pipes against freezing).
• Rocky terrain and call for BRH (Hydraulic Rock Breaker).
• Installations in cellars, above ground or on platforms.
• Discharge to the ditch or infiltration into the ground.
• Felling of trees or large vegetation.
• Secondary ventilation on the roof for many models.
• Outlet collection box for sampling.
• Volume of spoil to be cleared, and therefore in return sand for backfilling.
• Installation of 1 or 2 risers.
• Pump of lifting in entrance or in exit.

• Electricity consumption.
• Frequency (spacing) of oil changes.
• Cost of the maintenance contract or parts for the after-sales service.

The cost of installing an approved free-standing or fixed-culture micro WWTP.
The prices announced below include the supplies, the installation with ten-year guarantee of the installer and the commissioning according to the different criteria detailed in the previous paragraph (PE = Population equivalent).

The SPANC has a regulatory function which is to validate or refuse a request for the creation or upgrading of a non-collective sanitation system (NCS). Its responsibility is important insofar as, if it accepts a file that does not conform, the user can turn against it to ask for compensation.
 
The SPANC can only make a decision based on a complete and compliant file, in particular in relation to article 6 of the decree of September 7th 2009. This type of file is difficult to carry out by a user. Therefore, the SPANC generally asks that they be established by a research department specialized in soil studies and covered by a ten-year warranty.

The user is thus covered by the regulations:

•  The supplier of the treatment device who provides the ten-year guarantee on the equipment.
• The earthworker who covers the construction site with a ten-year warranty.
• The research department which guarantees the seriousness of the file and in particular the conformity of the study with the soil in place.
• The SPANC who finalizes the regulatory aspect of the project.

We have detailed in the table below the administrative and technical costs generated by the installation of a Non Collective Sanitation system.

The cost of an emptying varies from 240 to 350€ for a fixed price of 3m3 to remove. This cost varies according to the emptying company, the region in which you are located and the ease of access to your septic system.

The price can be higher if your house is located in an isolated area such as in the mountains or if the installation and especially the manholes are not easily accessible.

When half the volume of the septic tank is made up of sludge, it is necessary to schedule an emptying with a professional approved by the prefecture.
 
The French law specifies that "non-collective sanitation installations are regularly maintained by the owner of the building and emptied by persons approved by the prefect".
