|Project summary=The rivers of the Mediterranean countries are subject to intense human occupancy that causes problems in the exploitation of their resources. The overuse of water resources (urban, industrial and agricultural) leads to the following impacts on alluvial aquifers: The water table is lowered and the capacity of the bores is reduced; the drought period is extended, leaving the river bed dry for increasing periods; groundwater quality is reduced and urban water supply sources become polluted; protected wetlands dry up, biodiversity is lost and conservation problems arise.
	The Tordera Aquifer project will strive to reverse this trend by improving water management in the Tordera municipality. The objectives are as follows: improve quality of the sewage system; recycled treated water for conservation (aquifer recharge, establishment of wetlands); use of renewable energy and low-maintenance, soft treatment systems in the processes; serve as a pioneer example for other communities in the same river basin which can manage their water resources in a similar way.
	This project counts with the support of local, regional and European institutions. The financing comes from the LIFE initiative, the Tordera City Council and the Government of Cataluña. The total budget is 1.409.139€ (LIFE support 338.101€).
