Transferring water from the Ebro
was the alternative of the National Hydrological
Plan of 2001, which was cancelled when the Spanish government changed hands.
Diverted water would have high costs, with prices varying according to the distance from
the Ebro river (Uche 2003), and ranging between 0.20 and 1.05
3
(Table 5). These
3
price range currently paid by farmers, and at
these prices, the project water will only pay for itself in counties with high-profit crops.
The volume of imported water that counties can absorb at the prices of transferred water
is 761 hm
3
in Júcar, 294 hm
3
in Segura and 132 hm
3
in Sur (Table 3). These quantities
contrast with the planned water transfer targets of 141 hm
3
in Júcar, 362 hm
3
in Segura
and 58 hm
3
in Sur. Thus, there is a significant problem of inconsistency in the Ebro
project for the Segura basin, which can only absorb 294 hm
3
at the water transfer price,
which falls short of the 362 hm
3
assigned in the Ebro project to put an end to groundwater
prices are well above the low 0.06-0.21
