The Mayor of Valongo, Paulo Esteves Ferreira, emphasized the importance of a joint strategy, stating, "The Ferreira River knows no borders, so the response must be joint." The association will seek to identify problems, monitor water quality, and return the river to the public.

Paulo Ferreira, Mayor of Paços de Ferreira, highlighted the "special significance" of the initiative for his municipality, stating that "defending the Ferreira River is not just an environmental issue, it is defending our history, respecting our identity, and taking responsibility for the future".
Alexandre Almeida, Mayor of Paredes, pointed to the works at the Arreigada Wastewater Treatment Plant (ETAR) as "crucial" for the future of the Ferreira River and the importance of the new association in monitoring actions on the ground.
Pedro Machado, Vice-President of CCDR-N, praised the creation of municipal associations for stemming from "their own will" to combat common problems.
