In the course of its regulatory activity, ERSAR annually collects a very significant number of data (about 900,000) from the regulated entities, which are relevant to characterize the water and waste services provided to consumers.

​​​There is an enormous potential for relevant consumer information that ERSAR intends to make available and easily accessible to all interested parties and therefore, has created a mobile App.

The ERSAR App was initially developed in 2016 and was selected by the OECD as an example of innovation in the public sector. In 2022 the App was renovated and benefited from a set of new features. 

Available for download through Android and iOs mobile platforms.
