Allowing water to spring forth

Major infrastructure works starting from the reservoir of La Llosa del Cavall should enable the regions of Solsonès, Bages and Anoia (Catalonia) to enjoy improved drinking water supply.

Additional tools


More than a hundred kilometres of water pipelines, a drinking water treatment plant with a capacity of 28 000 m3 per day and three pumping stations will begin operating in 2013 in order to supply certain comarques in Catalonia that are undersupplied.

Solutions appropriate to the terrain

Catalonia, like the entire Mediterranean Region, has for decades struggled with a shortage of drinking water. In 1987, the Region adopted a penalty system for the largest consumers and began to address this crucial problem by means of various strategies. For instance, Barcelona has, since 2009, the largest desalination plant in Europe for urban use.

Other types of solutions, adapted to the geophysics and needs of the region, are being promoted. The ‘Network of drinking water supply from the La Llosa del Cavall dam’ is one example.

The new network will therefore be based on an existing structure. The dam is built on the Cardener River, which irrigates the pre-Pyrenees and the plains to the north-east of Barcelona. Developing this water resource as a source of drinking water should benefit the zones located downstream, supplying some 300 000 inhabitants.

Capture, treatment, supply

A system of pumps will provide the energy that is essential for the La Llosa dam to feed the new drinking water treatment plant (DWTP) established in Solana del Torrente. The plant, with a capacity of 350 litres/second, will be fitted with all the necessary treatment systems (oxygenation, pre-chlorination, settling, filtration, final chlorination, etc.).

A supply pipeline (76.4 km) comprising several branch pipes, will run from the DWTP to the city of Igualada. Three pumping stations are planned along this pipeline. The new network will make it possible to distribute drinking water to the comarques1 of Solsonès, Bages and Anoia.

Total and EU funding

The estimated cost of the ‘Network of drinking water supply from La Llosa del Cavall dam’ is EUR 21 006 871. The contribution of the European Regional Development Fund is EUR 16 805 497 over the 2007-2013 period.
