OECD creditor reporting system: guidance for the use of water supply and sanitation purpose codes

Purpose codes for water and sanitation have been revised taking effect in 2011 reporting on 2010 flows (agreed by the DAC Working Party on Statistics – WP-STAT – in May 2009). The purpose of this Note is to offer guidance to reporters using the revised codes; as such, the Note is “work in progress” and it is envisaged that the Guidance will be updated in the light of donors’ experience in applying the revised Codes. In offering guidance on the new purpose codes, this document also contributes to the higher objective of improving the overall quality of data in the water sector.
