Please note that even when the global SDG indicator is fully available, this table should be consulted for information on national methodology and other Moldovan-specific metadata information.

Indicator

Indicator 6.3.1: Proportion of wastewater sufficiently treated out of all discharged water, non-residential sector
Definition and concepts

Wastewater - water originating from domestic, social and economic activities, containing pollutants or residues that alter its initial physical, chemical and bacteriological characteristics.

Sufficient treatment - the treatment of water by any process and/or system, which after discharge of waste water allows the receivers to meet the relevant quality objectives in the technical norms and in the water management notices and authorizations in force.

Unit of measure

Percent, %
Method of computation

Volume of wastewater sufficiently treated / total volume of collected/discharge wastewater *100.
Comparability with global indicator

As compared to the global indicator, the national indicator includes only the water collected through the centralised collection systems (off-site) and not through the non-centralised system (on-site), the denominator provides only for total collected/discharged wastewater, and not total wastewater.

Related indicators

The domestic portion of wastewater treated is closely linked to indicator 6.2.1a on the “proportion of population using safely managed sanitation services”, and draws upon some of the same data sources.

The indicator is also directly linked to indicator 6.3.2 on the “proportion of bodies of water with good ambient water quality”, because unsafe wastewater treatment leads to degradation in quality of the receiving waters. It directly informs progress towards target 6.3 and is strongly linked to target 6.6 on water-related ecosystems, as well as target 14.1 on marine pollution (coastal eutrophication).
