The LIFE08 POWER project implies a qualitative and quantitative leap with regard to the objectives of the former project on which it is based; the LIFE03 OPTIMIZAGUA project was centred on the efficient water management exclusively. LIFE08 POWER introduces a second component to interact on the “water-energy binomial” on the basis of the “energy bill when moving water”.
In this sense, the project seeks:
a) On the one hand, to improve the hydric savings of the former experience already demonstrated by the former OPTIMIZAGUA project through the application of additional monitoring devices, such as the early leak detection with probes in soil in various deeps or of the water pressure degrees, as well as the use of new methods to calculate the hydric needs according to the phenologic cycle and real climate conditions contrasted to the “controlled flooding” estimations the current irrigation modalities are based on, usually over dimensioned.
b) On the other hand, and as a greater differential element in comparison to the former project, the demonstration and quantifying of the potential energy savings derived from both, the efficient water management and the generation of models to scale through renewable energy-based devices applied to water pumping systems and the subsequent quantifying of the reduction of emissions to the atmosphere are sought.
Considering the aforementioned, the quantifying of the environmental benefits, taking as a basis the use and application of the available technologies and the technologies used in the area, the estimation is 12% water saving additional to the results obtained by the OPTIMIZAGUA project as consequence of the technological arguments afore explained and a saving percentage higher than 60% of the petroleum-derived fuels consumption by the double way of: an efficient management of hydric resources complemented with the implementation of renewable energy to the pumping devices (and not only to the monitoring devices as in the case of the former OPTIMIZAGUA project).
One of the secondary results identified by the above mentioned project was the possibility of obtaining high energy savings associated to an efficient use of water and the strategic opportunity of assessing, through a new project, the potential of reducing greenhouse gasses emissions by incorporating lessons learnt in good water governance and their reinforcement through the incorporation of renewable energies-based applications to irrigation management systems.
