Methodological note

The indicator measures the percentage of population connected to waste water treatment systems with at least secondary treatment. Thereby, waste water from urban sources or elsewhere is treated by a process generally involving biological treatment with a secondary settlement or other process, resulting in a removal of organic material that reduces the biochemical oxygen demand (BOD) by at least 70 % and the chemical oxygen demand (COD) by at least 75 %.
