Non-Collective Sanitation (ANC) refers to individual domestic water treatment installations.

These devices concern homes which are not served by a public wastewater collection network and which must therefore themselves treat their wastewater before discharging it into the natural environment.

The treated wastewater is made up of black water (toilet water) and gray water (sinks, kitchen, washing machine, shower, etc.). ANC facilities must allow the joint treatment of all of this wastewater.

Non-collective sanitation therefore aims to prevent several types of risks, whether health or environmental.
