The Arrecife City Council has requested the state-owned company of the Ministry for Ecological Transition and the Demographic Challenge, ACUAES, to activate greater speed in the completion of the works on the new Submarine Outfall network in the capital of Lanzarote.

This state company is responsible for the execution of the works that has several areas of Arrecife, especially in the neighborhoods of Argana and Titerroy, where the new pipes of the WWTP waters are being channeled for evacuation through the submarine outfall network.

The mayor of Arrecife, Yonathan de León, has spoken with the works director of the construction company that is executing these works for the state company Acuaes. The mayor has requested "speed and agility in the development of the works that allow the reopening to traffic of the crossing under the ring road bridge, which connects the neighborhoods of Argana and Titerroy".

Yonathan de León, who has been in the area today, has conveyed to the construction company team the "many neighborhood and driver complaints about the pace of work by this state company." The mayor, who recognizes that "this is a complex work", which crosses the subsoil of several neuralgic roads of the city of Arrecife, has requested that "the extension of daily work hours and the provision of additional machinery be arbitrated, allowing the reopening to traffic of Calle Hermanos Álvarez Quintero, a neuralgic road that connects the neighborhoods of Titerroy and Argana, used to access the area of the University Hospital of Lanzarote, and the commercial area of Argana".

In addition to this road 'knot', under the ring road bridge, the new channeling of the submarine outfall crosses José Pereyra Galviaty street, in the direction of Vía Medular, where work remains to be completed in this sector.

 

A larger network due to the absence of treatment plants in Playa Honda and San Bartolomé

The state company Acuaes began in the summer of 2023 the execution of the works of the new Arrecife Submarine Outfall network due to the absence of treatment plants in the towns of Playa Honda and San Bartolomé, bordering the municipality of Arrecife.

In past decades it was decided that all the sanitation networks of this municipality adjacent to Arrecife should be channeled and treated in the WWTP (Wastewater Treatment Plant) in Montaña Mina, and evacuated through the Arrecife submarine outfall network. This work aims to cover the rise in the population of San Bartolomé, more linked to the one that Arrecife is experiencing, with a future investment throughout the subsoil of the capital of Lanzarote.

 

A work to cover the needs of 90,000 inhabitants

The improvements in the network, which are delayed due to the resistance of the soil to be drilled, will serve a population of 90,000 inhabitants (the sum of the residents in the municipalities of Arrecife and San Bartolomé). They consist of the construction of a new treatment plant, with greater treatment capacity than the current one, as well as the rehabilitation of the Submarine Outfall that allows the evacuation of the treated flows in the WWTP, a work that is affecting the mobility of the residents of Titerroy and Argana.

The new treatment plant will have a treatment capacity of 12,000 cubic meters per day of average flow compared to the current 8,000 and will be equipped with a tertiary treatment with a production capacity of regenerated water of up to 6,000 m3/day, for its reuse in agricultural uses and garden irrigation.

The action is co-financed by the European Regional Development Fund (ERDF), according to the agreement between Acuaes and the Water Consortium, for the execution, financing and exploitation of said works.
