This project aims at identifying, reducing and controlling the sources of wastewater drains and pollution in tourist ports inside commercial ports. The latter are especially affected by wastewater pollution discharged into their reservoirs, and all the more so when introduced in urban environments. The above is why the project will at first study and analyse the waters of the partner ports to determine the pollution rate and identify its specific origin. At the same time, existing good practices will be benchmarked, and the relevant stakeholders moved to the ports with the best practices (possibly outside the cross-border areas). Based on the above, the project will define common strategic guidelines for the creation of a concerted action of typical local piloting at each port. It will also involve the various procedures previously indicated to have an impact on water quality. All of this will allow the development of a joint action plan for the reduction and elimination of wastewater. Each partner port will implement a pilot action following the Joint Action Plan and involving the use of 'intelligent' water quality management and information systems, notably a test system. Thea will set up a quality control system of port water to determine the best pilot actions that can be reproduced. The results of the project will be detailed in a document to be disseminated throughout trans-border area ports.
