We always develop a broad proposal for the gminas concerned, presenting proposals for sewerage solutions for individual cities, including the proposed route of the network, the location of the vacuum station, the choice of pipe diameters and the size of the devices. We also provide the estimated costs of the investment and the expected costs of operating the network. We provide the addresses of networks operating in Poland, built with our participation using ISEKI technology. We provide the opportunity to organise visits to selected gminas to learn about the details of vacuum sewerage systems.
