The indicator is part of the EU Sustainable Development Goals (SDG) indicator set. It is used to monitor progress towards SDG 6 on clean water and sanitation and SDG 11 on making cities and human settlements inclusive, safe, resilient and sustainable.

Among other things, SDG 6 calls for ensuring universal access to safe and affordable drinking water, sanitation and hygiene, and ending open defecation. It also aims at improving water quality and water-use efficiency and encouraging sustainable abstractions and supply of freshwater. SDG 11 aims to renew and plan cities and other human settlements so that they offer opportunities for all, with access to basic services, energy, housing, transportation, green public spaces and others, while improving resource use and reducing environmental impacts.

Indicator can be considered as similar to global SDG indicator 6.3.1 "Proportion of wastewater safely treated".

Protection of water resources, water ecosystems and of drinking and bathing water is at the cornerstone of EU environmental policy, as confirmed in the 7th Environment Action Programme. EU water policy provides a framework to comprehensively address water protection and for achieving good status for inland surface waters, transitional waters, coastal waters and groundwater. The EU health and food safety policy also contributes to high standards on water and sanitation in terms of preventing the spread of communicable diseases. The EU in its external relations, its development cooperation policy (through the European consensus and the Agenda for Change), the European Neighbourhood Policy and the EU Enlargement Policy is supporting third countries in the achievement of this sustainable development goal through bilateral assistance programmes or regional initiatives. The EU Enlargement Policy promotes the extension of EU norms to candidate countries covering water quality, waste water treatment, but also water management and flood prevention.

The indicator measures the percentage of population connected to wastewater treatment systems with at least secondary treatment. Thereby, wastewater 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 %.

% of population.

Calendar year.

The indicator is produced according to the high-level quality standards of European Statistics. Details on accuracy can be found in the metadata of the source datasets (see link to related metadata).

ESS (OECD/ESTAT joint questionnaire)

Data source: Water Statistics of the European Statistical System (ESS).

Data provider: Statistical Office of the European Union (Eurostat), based on data reported by countries with OECD/ESTAT joint questionnaire.

Every 2 years

The indicator is updated every two years with annual data.

T+2 years

New data points are disseminated within two years after the latest reference year.

< 75% EU MS or no EU aggregate

No EU aggregate available. Data are presented for all EU Member States except Cyprus, Portugal and Slovakia; plus Norway, Switzerland, Albania, Serbia, Turkey and Bosnia and Herzegovina (by combining data points over 3 years).

All EU MS

Data are comparable between all EU Member States respectively other presented countries.

> 10 years

Presented time series starts in 2000.

> 4 data points

Length of comparable time series without methodological break is longer than 4 data points. Comparability over time is generally good, but can be limited due to data gaps and breaks in series.

Analysis of indicator is presented in Eurostat's annual monitoring report on Sustainable development in the EU (progress towards SDGs in the EU context).
