The Special Plan (controlled by the River Authority) and Drought Emergency Plan (by the water supply institution) are initiated. Several measures must be taken with respect to:

Public awareness campaigns

Alternative sources development

Changes in management system rules(priority demands, ecological flows…)

Approval of exploitation rules and use restrictions

Aquifers of strategic reserve

Temporal exploitation of the reserves

Emergency wells

Desalination

Reuse of treated wastewaters

Transfers of external resources

Furthermore, the Drought Special Plan must activate and serve as boundary condition for water supplying Emergency Plans for towns over 20,000 inhabitants

Drought Special Plan Effects

Planned conservation resources suppose a delay in the appearance of alert and emergency threshold and the development of new available resources to face drought represent 18.52 % of Jucar River Basin demands, acting as new offer in normality and pre-alert states, and as mitigation resources in alert and emergency states.
