An open irrigation canal between Calle Sant Faust and Calle del Dr Joan Mercader, which supplied the surrounding tanneries. The canal is made from brick, ranging from 90 to 140 cm wide depending on the sections, and between 80 cm and 3 m high. From 1967 and until the end of the 20th century several sections were covered and now around 350 metres remain uncovered, some of which were restored a few years ago with the creation of the Rec ring road, which runs parallel to the river course.
