Frontrunners and Followers
STOP-IT solutions are demonstrated through a front-runner/follower approach (FR/FL) where four advanced water utilities, Aigües de Barcelona (Spain), Berliner Wasserbetriebe (Germany), MEKOROT (Israel) and Oslo VAV (Norway) are twinned with four ambitious water utilities, Hessenwasser (Germany), Bergen Kommune (Norway), Emasagra (Spain) and DeWatergroep (Belgium) to stimulate mutual learning, transfer and uptake.
Aigües de Barcelona (Spain) manages the metropolitan public service of the water integral cycle, which includes the three branches referred above: water supply, sewerage and wastewater treatment and reclamation of treated water. At the moment, around 3.2 million people are served drinkable water in the Barcelona area. As far as sewerage is concerned, the whole process involves the transportation of wastewater through the sewers, the treatment of this water in the wastewater treatment plants and the reclamation of part of this treated water for agriculture or environmental purposes, among others. The sewerage network covers a population of 3 million people, distributed in the 36 municipalities. Not only is Aigües de Barcelona responsible for the management of the main sewers of the network, but also for the local sewerage of many municipalities included in the Barcelona Metropolitan Area.
