The total storage capacity of the reservoir is 4.150 billion m3 (3.150 billion m3 of which is its usable volume under normal operation) creating an inter-annual regulation capacity, from which water may be distributed throughout the region.
The Alqueva Multipurpose Project, managed by EDIA, irrigates an area of 130,000 hectares, produces reversible hydroelectric power, enabling full complementarity with other renewable energies (such as photovoltaic and wind energy) and supplies water for public and industrial uses, while contributing for the preservation of the natural and cultural heritage, the development of the tourism in the region and territorial planning. the city of Lisbon with 6 ha, several basins, 1000 trees, leisure areas and a bike lane.

​CAMPOLIDE SHIPYARD FOR THE LISBON DRAINAGE MASTER PLAN - DRAINAGE TUNNELS WORK

The Lisbon Drainage Master Plan aims to prepare the city for extreme events caused by climate change, to significantly reduce floods and the consequent social and economic costs, to create an infrastructure that allows water reuse (e.g., for irrigation of green spaces) and to close the urban water cycle – allowing to reduce the “invoice” of drinking water.
The plan includes a set of actions, namely the reinforcement and rehabilitation of the existing sanitation network, the construction of retention basins and the construction of two tunnels to conduct the excess water to the river, thus avoiding flooding.
