In the frame of the MENAWARA project, the Spanish intervention site is located at the AMAYA (Agencia de Medio Ambiente y Agua)´s Experimental Centre, in the small village of “Carrión de los Céspedes”, Southwest Spain in the province of Seville and at the near plot of olives trees, owned by local farmers. 

Although it has traditionnaly being a rainfed crop, in recent decades, an increase of irrigated olive groves in the area, due to the intensification of the crop and the improvement of productive yealds thanks to water use, contributed to enhancing the economic value of the sector. In fact, the olive grove represents the most established crop in Andalusia (511,593 hectares occupied by irrigated olive groves), becoming the backbone of the socio-economic development in rural areas, with a strong positive impact on agricultural, industrial and distribution companies.  At the environment level, the higher water demand (864 hm3 of water per year consumed by olive groves in Andalusia, 22% of the total demands in the region) has raised different problems such as the overexploitation of the aquifers. The use of treated wastewater constitutes a real and practical source of supply for the irrigation of the olive grove in Andalusia providing a local source of water.
