The project envisaged the development of water supply and sewage disposal networks in Šeštokai, Lazdijai district. Due to the characteristics of the existing terrain, in order to enable as many users as possible to connect to the centralized wastewater disposal networks, new vacuum wastewater disposal networks together with a vacuum wastewater station were designed and built at the site. The work project was prepared in cooperation with the representatives of the manufacturers of vacuum technologies and the project solutions were coordinated with them. According to this project, a Flovac (Germany) vacuum sewage station was installed.
