The proposed project is intended to contribute to the solution of this main problem: with increasing investments and development of infrastructure, the area of Kaunas FEZ is shrinking green areas and increasing the number of productive buildings due to which the amount of rainwater entering the current system of rainwater collection is increasing. The capacity of this system is already exhausted and in order to further develop the Kaunas FEZ, attract new investors and ensure the necessary conditions for them, the modernisation of the rainwater system is urgently needed. The aim of the project is to expand the infrastructure of engineering networks in the Kaunas FEZ necessary for attracting foreign direct investment in areas of smart specialisation. During the implementation of the project, investments will be made into engineering networks in Kaunas FEZ, where foreign companies will carry out R & D & I activities. The trunk drainage of rainwater will be reconstructed and installed. During the implementation of the project, it is planned to install about 3541 meters of trunk rainwater collectors from the point of transfer of the reclamation ditch in the territory of Kaunas FEZ to the point of the Ramučiai settlement in Centrinė str., to reconstruct the reclamation ditch by reinforcing its slopes.).
