Project summary

Edit project overview to modify the project summary.


The section corresponds to restore the stream of Ruby as it passes through the town from which it takes its name. In this section, the stream is strongly modified by the concrete walls built in the margins and along the breakwater that covers all the main channel and high water. Using previously vegetated materials and introducing local plant species, the objectives seek to: minimize the impact of the various works carried out within the stream, improve the quality of riparian ecosystems conjugating with the need to maintain hydraulic capacity and restore the banks the level that allows cleaning of exotic species and the planting of willow and herbaceous riparian own. The project has a total budget of 15.960,47 € and is financed by the Municipality of Rubí.
