A new sludge deposit at San Javier will prevent runoff from reaching the Mar Menor (09/10/2017)

The Ministry of Water, Agriculture, Livestock and Fisheries is carrying out the works of the lamination deposit at Avenida Patrulla Águila in Santiago de la Ribera, in the municipality of San Javier, to reduce the runoff to the Mar Menor.

The works, which began in September, cost € 2,116,906, financed by 80 percent by the Feder fund.

The infrastructure is scheduled to start before the summer of 2018.

The councilor Francisco Jódar, who visited today the progress of the works accompanied by the mayor of San Javier, José Miguel Luengo, said that "this action is part of the infrastructures planned to reduce discharges to the Mar Menor by external contributions of water from surface runoff in times of rain, the first of which, approximately the first 30 minutes, carry a high pollution load due to the cleaning effect of vials.

Jódar explained that "the lamination deposits have other important functions such as avoiding that in the rainy season the wastewater sewage networks overflow, storing the wastewater at specific times in which the pumping systems fail and, in the event of an electrical failure , avoid spills by storing water from the grid and give time to solve the problem caused by electrical failure.

The construction of the rolling deposit also includes the creation of two rainwater collectors-interceptors, which increase the defense against flooding and laminate the existing rainwater network.

Construction of collectors to collect rainwater

The collectors run through the Patrulla Águila, Nuestra Señora de Loreto, Francisco Franco and Castillo de Olite avenues.

Through the scuppers and road gratings provided, the collectors capture the rainwater that comes from Cobatillas and Mirador rambles, and intercept the existing rainwater networks.

The total length of the collectors to run is 1,664 meters.

The layout of the collectors will collect and transport the first rains to the interior of the deposit where they will be retained until their subsequent discharge to the general sanitation network.

It also contributes to the relief of the deposit when it reaches the maximum filling level, through the manifold projected in the street Castillo de Olite, which connects with the existing collector of Ronda de Poniente street.

The evacuation of the water retained in the reservoir will be carried out hours after the rains are collected, by means of the pumping provided at the lower part of the reservoir, for incorporation into the existing sanitation network and its subsequent treatment at the Wastewater Treatment Plant ( WWTP).

The execution of the works is completed with the paving of the vials affected by the collectors, the replacement of the affected services, all the electromechanical elements necessary for the operation of the water retention device and the urbanization and landscaping of the zone of location of the deposit integrated into the existing garden for the enjoyment of neighbors.

Execution program

The head of Water explained that the rolling deposit of Santiago de la Ribera is part of a program run by the regional government since 2014. Thus, a total of seven rolling mills are being worked on, six of which are already in march in San Javier, Cartagena and San Pedro del Pinatar.

To these deposits are added others that are in the study phase located in the Islas Menores (Cartagena), Mar de Cristal (Cartagena), Los Cuarteros (San Pedro del Pinatar) and in the WWTP of San Pedro del Pinatar.
