ERSAR, the Portuguese water regulator, has released an app (in Portuguese but with some English titles) from which "you can access to key information about water and waste services in each of the 278 Portuguese mainland municipalities. You may find information about the quality of service, news, tips and advices on how to use the services, among other features of this application."
top: water, sanitation, and waste. bottom: safe, treated and recovered
Do you know of other regulators that provide this information in usable form to the public?
