The Reno Galliera Union brings together eight municipalities in the metropolitan area of Bologna: Argelato, Bentivoglio, Castello d'Argile, Castel Maggiore, Galliera, Pieve di Cento, San Giorgio di Piano and San Pietro in Casale. It owes its name to the Reno River that bathes its municipalities and to the Galliera provincial road that runs through its territory, between Bologna and Ferrara. There are 75,193 residents (as of 12/31/2021) and the territory occupies a large portion (295.56 sq. m.) of the plain northeast of Bologna. Founded as an Association in 2001, it became a Union of Municipalities in June 2008, transforming itself to all intents and purposes into a Territorial Public Body, endowed with legal personality and governed by a President, a Council made up of the eight Mayors, and a Council composed of the Mayors themselves and a representation of the municipal councils. With its 217 employees, the Union manages, on behalf of its member municipalities, numerous services: general, personal, management, and territorial garrison services. Here, in detail, is the list of services that the municipalities have conferred to the Union: Human resources Financial services Associated computer service Statistical services Management control Single central purchasing authority Urban and territorial planning One-stop shop for productive activities Building, environment and fire prevention One-stop shop for productive activities Commerce One-stop shop for business projects Seismic practices Public works Local police Civil protection Education and schooling Social sector and territorial garrisons, Housing and Third Sector Territorial social service Culture, youth policies, tourism and sports Plan office of the Pianura Est social-health district
