GRP Wastewater Pipeline Along the Mediterranean Coast in Izola

The new sewer was installed on the route of an old narrow gauge railway, which had not been in operation since 1936 and which today serves as path for joggers and cyclists. Running along the sea, there are no differences in altitude so that the effluents are pumped through the 4.2 km line leading to the newly built wastewater treatment plant in Koper. HOBAS CC-GRP pressure pipes were therefore chosen. Apart from a lack in altitude which did not allow a gravity sewer, the coastal area bares another challenge, namely to the pipe material itself. Since saltwater is highly corrosive, one of the main reasons for choosing HOBAS Pipe Systems was the products’ corrosion resistance to such. Another crucial factor was to keep construction times as short as possible. The disruption of traffic on one of Slovenia’s main highways, that happens to run along the pipeline route, should be kept to a minimum. The installation was accomplished without major traffic jams and by keeping one lane open for the traffic. <,font face=",Times New Roman",>,<,font color=",#000000", size=",3",>,The investor Komunala Koper was very pleased with the installation speed. Thanks to a fast assembly facilitated by the easy handling of HOBAS Pipe Systems, the installation of the 4.4 km line could be accomplished within two months only. <,/font>,<,/font>,
