6.3.1 Population connected to wastewater treatment with at least secondary treatment

6.3.1 Proportion of domestic and industrial wastewater flows safely treated

6.3 By 2030, improve water quality by reducing pollution, eliminating dumping and minimizing release of hazardous chemicals and materials, halving the proportion of untreated wastewater and substantially increasing recycling and safe reuse globally

Goal 6. Ensure availability and sustainable management of water and sanitation for all

Indicator represents percentage of population connected to urban wastewater treatment with at least secondary treatment.

Secondary treatment of wastewater includes the biological treatment by secondary collection which BOD5 result is a reduction of at least 70% and COD at least up to 75%.

Tertiary treatment is the continuation of the secondary treatment where organic pollution is reduced at least up to 95% as for BOD5 and 85% as for COD.

The source of data is a statistical survey on wastewater from settlements. The methodological instrument used to conduct the survey is the Survey on Wastewater from Settlements, Questionnaire (VOD-2k).

Purifying wastewater means freeing it from hazardous and harmful substances and radionuclides to the permitted extent and making it harmless for use.

Data is collected annually.

The indicators are calculated using the quantities of treated wastewater through secondary and tertiary treatment and the estimated number of inhabitants.
