The Catalan Association of municipalities for public water management - AMAP was established in 2018. The association aims to ensure that water supply and sanitation services are guaranteed equally to all citizens, recognising water services as an essential and common good, which should serve public interests rather than corporate ones. 

AMAP represents 39 main Catalan municipalities and public water operators, such as Aqua Publica's member the Barcelona Cicle de l’Aigua SA (BCASA), covering a total of 44% of the population in Catalonia.

Through its dissemination, promotion and advocacy actions, AMAP, in collaboration with its members, is promoting the public management of water services. Furthermore, AMAP accompanies, advises and supports municipalities which wish to shift their water management model towards a public control. Likewise, the association plays a key role in Catalan political debate over water resources management.

AMAP joins the 65 public water operators and sanitation services operators members of Aqua Publica Europea.
