After 36 months of operation, the Watertur project has demonstrated that it is possible to improve water cycle management and reduce water consumption in hotel facilities.
The positive results of this work, carried out by different organisations, provide new stimulus to the Catalan hotel sector after the pandemic, as it can not only position itself as a benchmark in sustainable practices, but also improve its competitiveness in the face of the foreseeable implementation of stricter environmental regulations.
Watertur, which had a total budget of €1,536,798, is part of the RIS3CAT water community, promoted and coordinated by the Catalan Water Cluster. These communities receive funding from the Catalan Agency for Business Competitiveness (ACCIÓ) and the European Regional Development Fund (ERDF), and their aim is to combine efforts among companies, universities and research centres to integrate innovation into key sectors of the Catalan economy.
The place chosen for the implementation of this project was Vilar Rural in Sant Hilari Sacalm, where the three proposals put forward by Watertur were validated and operated either partially or in full.
Three sustainable ideas
The first of these technologies was an anaerobic membrane bioreactor operated in conjunction with a vertical wall coupled with a bioelectrochemical system. An innovative solution developed by Sorigué, in cooperation with the company Aeris Tecnologías Ambientales and the LEITAT technology centre. The bioreactor has not only guaranteed 83% efficiency in the reduction of organic matter in wastewater, but has also removed 100% of pathogens from the effluent thanks to its membrane system.
