Multiple purposes

Alqueva is based on the principle of multiple purposes and integrated management of its strategic water reserve.

Alqueva is blazing trails to water. These are trails that lead to the public mains, by reinforcing five dams that supply water to around 200,000 inhabitants, for agriculture, with an equipped irrigation area of around 120,000 hectares, for industry, for generating clean energy and for tourism.
