The purpose of this indicator is to ensure that human and industrial effluents are disposed of without danger to human health or unacceptable damage to the natural environment.

This indicator covers households and the entire economy, and builds on the monitoring framework of JMP, UNSD/UNEP Water Questionnaire for non-OECD/Eurostat countries, OECD/Eurostat Questionnaire for OECD countries, AQUASAT, IBNET. Statistical methods for measurement of wastewater treatment is aligned with the SEEA21 statistical standard and associated definitions, classifications and treatment categories (Encompasses all wastewater generated and treated by the economy). Treatment Categories will be consistent, as much as possible within the context of global monitoring purposes, with those defined in the SEEA, and International Recommendations for Water Statistic.

The household portion of wastewater is the same indicator as 6.2.1, and the monitoring of that will be interlinked to JMP monitoring for 6.2.1. Over the last 25 years the JMP has established global norms and standards for monitoring drinking water, sanitation and hygiene. The proposed 6.2.1. indicator builds on these and was developed following extensive consultations with sector experts. Major international consultations took place in 2011 and 2012, as well as many regional and country consultations in various parts of the world.

System of Environmental and Economic Accounting for Water adopted by Statistical Commission in 2014. This accounting structure means that these activities cover the whole economy and are considered for each industry, which are defined according to the International Standard Industrial Classification of all Economic Activities (ISIC), and covering 1) abstraction and distribution of water, 2) discharge, reuse and treatment of wastewater, and 3) consumption and returns of water back to the environment, in this accounting structure, disaggregated by industry in a standardised way. Economic activities by ISIC broadly covers agriculture, hazardous industries and other economic activities.

This indicator is disaggregated for households and non-households (industrial and commercial establishments).

The calculation of the indicator value as derived from the framework is the amount treated (off-site and on-site) divided by the total amount of waste produced. Data on treatment of domestic wastewater will come from the multi- purpose indicator 6.2.1. Data on volumes of industrial wastewater can be estimated from inventories of industries, which will be available in most of the Member States disaggregated by ISIC classifications. The breakdown of treated wastewater can be calculated based on compliance records, related to national standards. Unless verified otherwise, through audited compliance records, the waste generated will be considered untreated.

This indicator can be used to measure the proportion of wastewater generated by households and by economic activities which is safely treated based on treatment ladders as defined by the SEEA.

The main issue regarding safely managed drinking water services will be comparability of data on the definition of what is considered safe treatment.

Using MDG experiences of data reconciliation and working collaboratively with JMP on this will help reconciling definitional discrepancies and hence variations in estimates. This vast experience in dealing with such issues will be very useful in dealing with the above issues for the SDG period.
