The indicator refers to the volume of municipal wastewater collected by public sewage networks, septic systems and cesspits, and the volume of wastewater treated in wastewater treatment plants. Here reference is made to primary (mechanical) treatment that removes part of the suspended solids, and secondary (biological) treatment that uses aerobic or anaerobic micro-organisms to decompose most of the organic matter and retain some of the nutrients (around 20 - 30 %). Tertiary (advanced) treatment removes the organic matter even more efficiently.
