Forming part of a larger scale water project in and around the Guadiana River, the project will also contribute to the local economy and its development through the creation of jobs.

Working with river systems

The large-scale project ‘Ligação Pisão-Roxo’ forms part of the Alqueva Dam project. The Dam was built on the Guadiana River in the region of Alentejo, southern Portugal. The River itself has already benefited from funding support in projects under the Structural Funds (total European Regional Development Fund financing for the 2007-2013 period: €275 000 000). Such funding has been seen as an ‘anchor’ investment for development in the region. The Alqueva Dam provides critical infrastructure for the local water system and is used as a primary storage place and for lifting and transporting water. Secondary infrastructures have also recently been constructed for water supply and irrigation purposes.

Added boost to water supply

The Alqueva project is composed of a total of 15 dams, 314 km of canals, nine pumping stations and six mini-hydroelectric power stations, among other infrastructure. ‘Ligação Pisão-Roxo’ represents one of the three subsystems of the overall water supply system of Alqueva. The current project has been designed to help complete its primary water supply network. The project works will be undertaken in the district of Beja, and will cover the municipalities of Ferreira do Alentejo, Beja and Aljustrel. As far as the employment impact of the project is concerned, a total of 40 new jobs are expected to be created once the network is up and running.

Longer canals reach more residents

Several key indicators/results have been established as part of following up the project. First and foremost, one dam will be built and will form part of a large network which will eventually see 23.13 km of water canal extensions. In terms of project beneficiaries, the additional population covered by the upgraded drinking water supply systems is estimated to be 44 486.
