The aim of the project is to protect the buildings and nature of the region along the border, and to get started the common sociable, economic and social activities in he concerned municipalities and in The Medzibodrožie region. The water, like a resource of the environment, affects the life of the community and the environment quality. Water basis constitutes extraordinary value, and just these resources are threatened by the contaminations from the illegal sludge water discharge from the towns and villages to the nature. That´s why it´s very important for the cities and villages to build up the canalization in their cadastres. It´s exactly obligatory for them to drive-away and defuse the communal sewage water in the both states. The project partners are building up a sewerage system within the project. 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.
