Sorigué has taken over maintenance services for the technical facilities and equipment of Ens d’Abastament d’Aigua Ter-Llobregat (ATL), a Government of Catalonia state-owned enterprise producing and supplying drinking water for more than 5 million people in 117 municipalities in l’Alt Penedès, l’Anoia, el Baix Llobregat, el Barcelonès, el Garraf, el Maresme, la Selva, el Solsonès, el Vallès Oriental and el Vallès Occidental.  
 
The new contract began on 1 January 2024 and runs for a period of five years. It includes all the production assets managed by ATL. Sorigué’s role consists of carrying out all preventive and corrective maintenance work on the water treatment and desalination plants, pumping stations, tanks, manholes and piping. 
 
Sorigué has the equipment, tools, materials and human resources needed to deliver services all year round, including 24-hour emergency response teams to deal with urgent breakdowns. 

The group has been running this service since 2017, although it had previously undertaken some of the actions it is now performing such as repair and maintenance of pipelines, buildings, technical systems and equipment and maintenance of the network manholes in the southern area. 
 
This new contract includes scheduling planned repairs and immediate fixing of any kind of break in supply pipes, building or civil engineering structures, mending damage to public roads or private land as a result of a fault and restoring any technical systems or equipment impacting service continuity. 

Sorigué is additionally in charge of applying anti-corrosion paint treatment to desalination facilities, industrial cleaning of production plants and distribution networks and minor repairs to ensure all systems are operating smoothly. 

Field of action 

Divided into two zones, the contract covers firstly the northern zone, which includes the Ter drinking water treatment plant (DWTP), a 1,720 km2 distribution network, and the Tordera desalination plant (DP). Meanwhile, the southern zone takes in the Llobregat and Cardener DWTPs, a 1,550 km2 distribution network, the Llobregat DP and the OC Fontsanta distribution station. 
 
The Ter DWTP is in Cardedeu, receives water from the Pasteral reservoir and has a treatment capacity of 8 m3/s; the Llobregat DWTP is in Abrera, harvests and raises water from the Llobregat River and produces up to 3.2 m³/s, and finally the Cardener DWTP is in Navès, Lleida, and has a treatment capacity of 0.35 m3/s of water from the Llosa del Cavall reservoir.  
 
Once the water has been through the treatment stages, it is stored in tanks and distributed to the municipalities connected to ATL’s regional network which monitors and ensures its sanitary quality.  

As for the desalination plants, the Tordera DP adds some 20 Hm3/year of treated seawater to the drinking water network and the Llobregat DP some 60 Hm3/year.

With an extensive track record in the water infrastructure industry, Sorigué has over 60 years of experience in all water-related services such as building and maintaining networks, connecting supply systems, fitting valves and maintaining upstream transport networks and sewage systems.  

It now operates almost all over Spain and its most recent projects include conservation and maintenance of Malaga’s water supply and sewerage systems along with comprehensive maintenance of the drinking water supply and sewerage system in the Huelva Water Network.
