Gouvães, Portugal

The upper bifurcator was prefabricated and test-assembled in Austria for the purpose of measurement. It was delivered in parts to the construction site in Ribeira de Pena, Portugal. After installation at the final destination, the bifurcator was equipped with pressure covers and successfully subjected to a pressure test with 100 bar (corresponding to a head of 1,000 m).
