These Guidance Notes represent the collective experience and sustained efforts over a 10 year period of six international specialists who are committed to the ‘free to all’ dissemination of good practices in management of Non-Revenue Water. The Apparent (Commercial) losses component of NRW tends to receive less attention, with fewer easily accessible publications, than Real (Physical) losses. These Guidance Notes, with the accompanying 9 separate Appendices, and other freely available material on the LEAKSuite Outreach (App loss) webpage, seek to reduce that imbalance.
The Guidance Notes format of 1 main document and 9 Appendices has been used so that each of the 10 documents can be updated separately in future, or additional Appendices can be added. Any future changes will be documented on this webpage.

The Guidance Notes document contains Sections on Water Balance and Apparent Losses; Water Audit Component Analysis; Apparent Losses Indicators; Action Planning and Dynamics of Losses; and Economics of Apparent Losses. Each of the Sections has a set of References (some with weblinks to free papers). The Bibliography lists 74 papers and books. Each of the Appendices also has its own set of References.
