the rise ecological flow It will mean reduced shipments for the province of Alicante, imposed by the Tagus Hydrological Plan. This for Segura basin From 70 to 110 hm3 per year from 2027. The cutback is gradual and has already started for 7 hm3. However, in 2026 and 2027, it will be 8 and 8.65 hm3, respectively.
To deal with this situation that threatens our future, province of AlicanteThe Valencia Community Business Confederation (CEV) considers it necessary to initiate and immediately carry out all these actions that make it possible to mitigate negative impacts. Among these measures, Evacuation Plan 0execution and authorization of pending infrastructures water resources From Júcar-Vinalopó transfer, instead Extraction of groundwater from Vinalopó-Alacantí and development of complementary studies Mutxamel desalination plant.
An intervention package presented and analyzed at the joint meeting of the CEV executive committee members and the CEV Alicante board this morning in the USA MARQThen they had the opportunity to visit. Xian Warriors Exhibition.
In the report, in which the studies were carried out, all emergency actions “that the administrations should take urgently” were determined, taking into account the regulation change. Transfer of Tagus-Segura and overexploitation of Vinalopó-Alacantí aquifers.

Regarding the Evacuation Plan 0 from the Confederation of Business, investments are required to achieve the goal. 100% reuse of water from treatment plants in the Alicante metropolitan area.
When the foreseen works are finished, the volume of water discharged into the sea is about 19.5 hm3/year and that part of these Flows must be treated by osmosis to reach a conductivity level of 1,800 mS/cm2 with the corresponding rejection.
A Critical point for the viability of this action It is the necessary reorganization in concession allocation that guarantees transparency and efficiency in the allocation of water rights. And this, because it will have additional 15 hm3 It should be assigned to those affected by reduced flow of Tagus-Segura transfer.
Transfer Jucar to Vinalopó
Regarding the execution of pending infrastructures and authorization of resources from Júcar-Vinalopó, CEV, Júcar-Vinalopó on the left bank after the transferReplace groundwater with surface water for use by irrigation and change the rules of use of the Júcar system to enjoy its benefits. excess.
The purpose of the Júcar-Vinalopó pipeline is to improve environmental quality and reduce environmental pollution. overuse of the Vinalopó aquifers, by stopping the extraction from them for irrigation of groundwater and replacing it with surface water.
This Júcar-Vinalopó pipeline is designed to transfer 80 hm3 per year and costs approx. 400 million €. The Júcar Hydrographic Confederation (CHJ) has an agreement with the Vinalopó, l’Alacantí Central User Board and the Marina Baixa Water Consortium to recover groundwater, with an allocated volume of 34.1 hm3/year for 2027 and beyond. the masses.
The remaining streams (45.9 hm3), CHJ can assign to other users with current limitations. Júcar Hydrological Plan and future rules for operating the system.
Entrepreneurs believe that CHJ should ensure that these flows meet the reductions in Segura contribution, especially to the irrigated area of the Júcar border, taking advantage of infrastructures like these Riegos de Levante. To this end, within the framework of government mandates, authorizations should be processed in the current planning cycle to meet the demands of users who see their resources running low.
Then, transfer Surpluses of Júcar al Segura from the Marquesa damtaking advantage of existing infrastructures.
San Diego Reservoir

This is a study not included in the 21-27 hydrological planning cycle and it will be necessary to regulate and allow the volumes of the Júcar Vinalopó transfer assigned to the Vinalopó-Alacantí system, as indicated by the CEV. meet the demands of new users. And for all this to be effective, amending the operating regulations of Júcar-Vinalopó and issuing relevant permits, as well as photovoltaic installations for pumping water.
Mutxamel desalination plant
Regarding the replacement of groundwater extraction from Vinalopó-Alacantí and the execution of complementary works of the Mutxamel desalination plant, it is stated that its purpose is to connect the Mutxamel desalination plant to the municipalities of Campello and Mutxamel. This volume from the Mutxamel desalination plant will mean a reduction in the extraction of wells from the over-used aquifers that supply water to Mutxamel and El Campello. It is estimated that an additional 5.7 Hm3/year of water will be obtained with this process.
Infrastructures involved in the actions include the regulatory and distribution work necessary to supply potable water from the new Mutxamel desalination plant to the municipalities of Campello and Mutxamel (Alicante) and to connect the system to the Rabasa-Amadorio pipeline currently in use. .
Construction of approximately 26 km of pipes with different ductile diameters, starting from the Mutxamel desalination plant, carrying the treated water from the plant to different tanks, both existing and newly built:
Supply to the municipality of Mutxamel: Propulsion starts from the desalination plant and after an interim re-pumping supplies water to the existing Llanos reservoir and its extension. On the other hand, two connections are made with the Phenollar-Amadorio pipeline: on the one hand with the Llanos extension reservoir and on the other hand with the Salt reservoir (existing) from which a pipeline is run to the reservoir. .del Collado, again newly built (2,500 m3 volume).
Supply to the municipality of Campello: The new pipeline starts from the newly built reservoir in Ramellat and with the existing 7,350 ml pipelines without bypass branches and two pumping stations connected in series, potable water is raised to a new reservoir during construction in Xixí2 (2,500 m3 capacity) (instead of existing capacity) An intermediate bed is also being built (Xixí 1, 6,000 m3).
Output regulation tank of IDAM Mutxamel for a volume of 40,000 m3 to regulate production and urban demands.
Vega Baja water deficit
Finally, regarding the irrigation water shortage in Vega Baja, CEV warns that irrigation will be interrupted in the Vega Baja area. Severely affected by the decrease in the flow of the Tagus-Segura transfer.
In this area, almost 100% of the streams treated for irrigation are already reused, so no additional contribution from water treatment can be expected at this time.
On the other hand, General Directorate of Water The Ministry of Agriculture has announced a €15m project to reuse rainwater from Torrevieja and Orihuela Costa to provide new water sources to surrounding farming communities. Torremiguel, San Miguel de Salinas and La Pedrera.
However, businessmen think that this project is insufficient and additional activities are needed to provide stable and economically sustainable water resources to the irrigationists. Therefore, they advocate the allocation of water concessions.
