Litter toilets, more commonly known as dry toilets or composting toilets, are more and more popular in France! This is why, the legislation ruled on the regulation of these ecological cabinets, defined as being "without the addition of dilution or transport water". Since 2009, there are therefore rules to follow to build, install and use these toilets like no other. Manual.

Measures to take into account for installation

Dry toilets are a non-collective sanitation system, but since 2010, they can also be installed in a collective sanitation area without specific declaration. However, you sometimes need a building permit to be able to make your own composting toilets. Several parameters are then taken into account (height and width of the toilets, installation area, waste disposal, etc.). Depending on your case (to be checked in the town planning code), you can be exempt from any administrative procedure. Otherwise, you will need to apply for a building permit from your town hall.

Three principles imposed for construction

French regulations impose three criteria on dry toilets for individuals and professionals. They must not generate "no nuisance for the neighborhood", "nor liquid discharge outside the plot", "nor pollution of surface or groundwater". Three principles must therefore be observed: a sealed tank to avoid any source of pollution; a sealed and weather-protected area, onto which the waste is dumped; use of compost recovered only on the plot. The principles mentioned above will be subject to control by the municipality or the SPANC (Public Service for Non-Collective Sanitation). In the event of non-compliance, you will be asked to make the necessary adjustments. A follow-up visit will then determine if you are in good standing.
