The river in the city suffer ups and downs during the course of the work in order to facilitate drying of the different sections
This action joins the improvement in the quality of the waters of the Segura, has been achieved in recent years thanks to Plan purification and reuse of the Region of Murcia
Today begins the works that will restore hydraulic capacity of the Segura River in the city of Murcia.
The draft environmental recovery, holding the Hydrographic Confederation of Segura (CHS) under the Ministry of Agriculture, Food and Environment, began three months ago with a biological treatment to reduce odor, but is expected to date for the entry of the machines to the channel in order to avoid discomfort during the Spring Festival and the bridge in May.
The CHS, funded by the Directorate General of the Ministry of Water, plans to invest a total of 4,311,450 euros in dredging.
The timing to complete the performance is April 2015.
The area where sediment removal is performed almost all urban riverbed, between the bridge of the A-30, west of the city of Murcia, and the bridge of Fica, east a stretch of 2.4 kilometers in which the waters are partially dammed.
It is expected that the river bed is lowered by one meter, which will restore hydraulic capacity he had the runway in the fifties.
The islets of sediments that have been formed in the urban runway over the years will also be deleted.
After the performance, the river will have a 50-meter wide and a low-water channel of 10 meters.
The work is a new step in the work of regeneration of the river, which has allowed, in just ten years, the quality of the waters of the Segura move from being the most polluted Spain to lower pollution in all sections.
This process has been recognized by numerous international publications and has been possible thanks to an intense effort in the development of treatment systems and reuse undertaken by the Government of the Region of Murcia and the Ministry of Agriculture, Food and Environment resources.
In all, some 150,000 tons of sediment will be removed.
To minimize the inconvenience to neighbors, began three months ago bioremediation treatment, comprising the application of a microbial-enzyme product on the lees.
Thanks to this process is able to reduce the amount of biodegradable organic matter and thus eliminate most of the odors that may be generated during dredging operations.
The removal of sediment will be done through a system-drying areas to while working in each sector, bounded by levees, the water will continue to run for the rest.
Thus, the urban stretch of the river is divided into ten subsections (nine in the city and one further upstream, between Manterola and motorway) on which work consecutively, beginning and ending in La Fica El Malecon.
The previous studies in laboratory on samples taken from the riverbed in Murcia show that it is waste that can be reused.
The CHS has decided to take advantage of these sediments as fill material and restore Segura meandering through your deposit and mixed with the existing soil.
To this end, we have chosen two groves located downstream of the sewage Murcia Este, which are in part been abandoned and will be graded and rehabilitated after the deposit of materials.
