Drilling works have started in the experimental site located in Sant Vicenç dels Horts (Barcelona). These works are included in the Action 4 of the ENSAT project, and consists of a well (350 mm diameter) that will allow pumping tests, and two observation wells downstream. Moreover, three observation wells will be drilling in the infiltration pond. This new instrumentation in the saturated zone will complement the existing network of piezometers in the experimental site.
This first phase of instrumentation will finish at the end of June. After that, pumping and tracer tests will be performed.
