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 information that ERSAR intends to make available and easily accessible to all interested parties, and since one of the tools that has been shown with great potential for information availability is mobile applications (apps), this regulatory entity developed this digital communication platform.

The ERSAR app was selected by the OECD in February 2016 as a case of innovation success in the public sector.

The app is available for Android and iOs mobile platforms.
