This chapter addresses the potential impact of free trade agreements on services of general interest which are provided in the context of local self-government and discusses how these agreements could interfere with Article 4(2) TEU. The chapter uses the provision of drinking water by local utilities in Germany as an example case study. The chapter begins with a brief overview of the current regime for the supply of drinking water, particularly with regard to the involvement of structures of self-government. Next, the chapter examines whether the provision of drinking water and the involvement of local self-government therein are likely to be influenced by free trade agreement regulation and, if so, to what extent. Finally, the results of the former analysis will be presented in relation to the EU primary law provision of Article 4(2) TEU.
