In this way they will consist with the law, they will contribute to the environment protection and will increase the living standard of their inhabitants and of the surrounding townships too. The Slovak partnership villages are not able to get connected to the existing sewage tank, that´s why there will be built up a sewage tank on the Slovak side. In The town of Sárospatak, there exist a sewage tank and a sewerage system, that´s why there won´t be built up a new one. The new sewerage system which will be built up in The village of Vajdácska within the project, will be attached to the sewage tank of the City of Sárospatak.
