Water - Wastewater treatment - OECD Data

This indicator presents sewage treatment connection rates, i.e. the percentage of the population connected to a wastewater treatment plant. “Connected” means actually connected to a wastewater treatment plant through a public sewage network. It does not take into account independent private facilities, used where public systems are not economic.This indicator is measured in percentage.

Wastewater treatment - Wikipedia

Wastewater treatment is a process used to remove contaminants from wastewater or sewage and convert it into an effluent that can be returned to the water cycle with minimum impact on the environment, or directly reused. The latter is called water reclamation because treated wastewater can be used for other purposes. The treatment process takes place in a wastewater treatment plant …
