The Recharge Dams Construction Plan for the Alicante Province (administrative division within the Comunidad Valenciana in Spain) is a proposal of the Diputación de Alicante, as a result of the previous studies undertaken by the Departamento de Ciclo Hídrico (Department of Water Cycle). Runoff series for all the provincial subbasins for the rainfall events of the past 50 years have been generated, possible impoundment volumes over permeable grounds have been analyzed and a group of them have been chosen attending to certain criteria. Afterwards, for the selected dams, inflow runoff series have been generated, modeling infiltration into the ground and estimating both infiltrated volumes as well as its costs. Finally, after comparing with empirical data of instrumented basins for continuous runoff record, the construction of 52 in three horizons is proposed: Phase 1: the 25 most interesting, with a target of 7,94 hm3/year infiltrated, with average cost of 0,09 €/m3 and total cost of 12,10 millions of €. Phase 2: 18 ‘serial dams’ to regulate runoff that has not been regulated in phase 1, with a target of 6,9 hm3/year infiltrated, with average cost of 0,08 €/m3 and total cost of 10,2 millions of €. Phase 3: 10 ‘pilot dams’, in principle less profitable but very interesting to obtain data in mountain basins, with a target of 0,9 hm3/year infiltrated, with average cost of 0,31 €/m3 and total cost of 4,9 millions of €.
