Pursuant to Human Rights Council Resolution 27/7 of 2014, the Special Rapporteur on the human rights to safe drinking water and sanitation, Mr. Léo Heller, was mandated to work on identifying challenges and obstacles to the full realization of the rights, as well as protection gaps, good practices and enabling factors.

In August 2015, the Special Rapporteur presented his report on affordability and the human rights to water and sanitation to the United Nations Human Rights Council.

Moreover, on 16 June 2015,the Special Rapporteur also held an expert consultation with experts on affordability, human rights and water and sanitation from various fields.

Access to affordable water and sanitation services is crucial for the realization of the human rights to water and sanitation. Where water or sanitation services are available but not affordable, people will not be able to use sufficient amounts of water and adequately maintain latrines, or will turn to cheaper, unsafe sources or practices, or will compromise the realization of other human rights such as food, housing, health or education.
